Abstract

A test result of a conventional perimeter does not faithfully reflect the shape of a subject's dark spot blind spot. A conventional perimeter may not detect glaucomatous dark spots. In addition, since the visual field inspection is monotonous and requires a long inspection time, an erroneous reaction of the subject may occur.
The computer can be immediately used as a perimeter and a retinal visual function test meter. The inspection result becomes a beautiful scan diagram with sequential two-dimensional gray scale display and displayed on the display during the inspection, reducing the monotonicity of the visual field inspection. Since the inspection method uses two visual targets alternately, the inspection speed is dynamically increased in the off-center visual acuity, while the inspection details are statically increased in the macula. Generate scan diagrams by using the horizontal and vertical inspections in an accumulative manner. Since an objective and detailed examination is possible compared with a conventional perimeter, a glaucomatous dark spot that cannot be detected by a conventional perimeter can be detected. The visual function level of the visual function-decreasing area is also displayed in a scannable manner in an intuitively understandable manner.

Description

  The present invention uses a visual field function state of a subject continuously while alternately converting two points of a dynamic visual target and a static visual target, and accumulates visual field inspection information in the horizontal direction and the vertical direction. A computer comprising a visual field functional function inspection method that achieves high-speed full-field inspection while simultaneously having inspection accuracy with a spatial resolution of 10 minutes or less. Regarding the program.

  Conventional perimeters include the following (for example, see Reference 1).

  Goldmann perimeter, 510 type (1945), 940 type (1967), Tubinger perimeter (1957), Octopus perimeter (1976).

A conventional perimeter will be described. Goldmann perimeter is the first brightness perimeter and manual simultaneous recording type. Target brightness is 4 to 60 types, target viewing angle is 6 types, viewing angle field and background brightness can be adjusted. The disadvantage is that it is impossible to measure the center within 5 °. Tubinger perimeter (1957) is the first practical static perimeter. Dynamic visual field, color field, flicker field, etc. can be measured. Manual simultaneous recording type. Target luminance 80 types, fixation target luminance 100 types, color 5 types, background luminance 6 types. Central and external visual acuity measurements. The disadvantage is that it is difficult to move the target, and it is difficult to adjust the target, fixation target, and background light. Octopus perimeter (1976) is the world's first fully automatic static perimeter.

The problems of the current perimeter, the basic perimeter currently in use, have not been improved since its development around 40 years ago.
Since the perimeter used in the current visual field inspection is a manual simultaneous recording type and a manual dynamic visual field inspection, the accuracy of the inspection is not constant over the entire visual field. In addition, the test result is influenced by the method of moving the target of the recorder, and the test result record does not faithfully reflect the dark spot, blind spot shape, and mutual positional relationship of the subject. If the recorder hears from the subject about visual field impairment, the test results are affected. The entire field of view cannot be inspected uniformly. The degree of visual impairment at the dark spot for the macular region, which is important for central vision, is not intuitively reflected in the test results. Areas with slightly damaged pyramidal cells are not displayed in the test results. Inspection time is long. Since the test is monotonous with a constant period, an erroneous response to the visual target due to the periodic habituation of the subject may occur. The shapes of dark spots and blind spots detected for manual recording are very rough, and the figure of the test result is considerably different from the actual shape of the dark spots and blind spots for the subject.

  In the fully automatic static visual field inspection used in the current visual field inspection, the space separation ability visual acuity of several degrees or less cannot be inspected in order to shorten the entire visual field inspection time. The perimeter used in the current visual field inspection shortens the inspection time for measuring the entire visual field, so whether it is manual static visual field inspection, fully automatic static visual field inspection, manual dynamic visual field inspection, It does not have the ability to detect areas with reduced visual function of several degrees or less.

  However, there are cases in which the area of the connection from the dark spot to the blind spot, which is said to be characteristic for glaucoma dark spots or macular neovascularization dark spots, is several degrees or less (see glaucomatous or neovascularization dark spots 4 in FIG. 1). This is not detected by the perimeter.

In the case of the current fully automatic dynamic perimeter, since the moving direction of the dynamic target is random, the visual field space resolution inspection information is not accumulated in the examination results. The test results do not reflect the shape of any of the subject's dark spot blind spots. However, the inspection time is very long. Since the examination is very monotonous and repeats a certain period, the subject is likely to make an error response due to the periodic learning effect of the appearance of the stimulus, familiarity, and the like.

The recorder, the inspection method, and the scan type output method of the inspection results were computerized by a program.
In the case of full-field measurement, the horizontal visual field inspection was speeded up precisely by using two points of the dynamic visual target and the static visual target alternately. With the vertical position of the dynamic and static targets fixed to the center of the display, the test results are sequentially scanned from the bottom row by sequentially moving the fixation target vertically downward (see FIG. 1). .) Is generated.

  The spatial separation ability of the central visual acuity is high (FIG. 1, central visual acuity 14), and the spatial separation ability of the central external visual acuity is low (see central external vision 6 of FIG. 1). As the visual field is farther from the center, the number of pyramidal cells decreases, so the spatial separation ability decreases. In areas with low spatial resolution (see FIG. 1, external visual acuity 6), the dynamic visual target speeds up the examination. However, since the dynamic visual target moves at a constant speed in the horizontal direction, the inspection accuracy is uniform. Central vision and non-central vision functions can be inspected uniformly. It is possible to perform a test that is not affected by the judgment of the writer and the preconception about the visual field of the subject. Information on the degree of spatial resolution detected by the dynamic visual target is statically obtained by alternately linking the dynamic visual target and the static visual target without spatially separating them (see FIGS. 5 and 7). It can be stored in the inspection record as a visual target. The test result is a retinal function two-dimensional scan.

  Humans can respond quickly to moving objects. Dynamic visual targets are less susceptible to visual familiar afterimages than static visual targets, and the examination time can be shortened by reducing the subject's confirmation judgment time for the appearance of the visual target.

  The two-point target system for the full-field inspection is shown below (see FIGS. 3, 4, 5, and 6). Block the eyes that will not be inspected. First, the subject gazes at the fast flashing fixation target on the display with the eye performing the visual field inspection. The dynamic visual target A appears from the display while moving in the horizontal right direction (see 3 in FIG. 3). When the subject can recognize the movement of the dynamic visual target A in the visual field, he or she presses the button or the space key. The dynamic visual target A becomes a static visual target A dash at that position (see 22 in FIG. 5). With the static target A dash continuously displayed, the dynamic target B having the same shape and size starts to move in the right horizontal direction at the same speed from the position of the static target A dash (FIG. 4). 12). Press the button or space key when the subject recognizes the two points of the static target A dash and the dynamic target B, or the movement of the dynamic target B in the field of view, based on the spatial separation ability. . The static target A dash disappears from the display, and the dynamic target B becomes the static target B dash at the position where the button is pressed. With the static target B dash displayed, the dynamic target C appears from the position of the static target B dash and starts moving in the horizontal direction at the same speed to the right. The button or the space key is pressed at the stage where the appearance of the dynamic visual target C with respect to the static visual target B dash is recognized by the subject's spatial resolution or the movement of the dynamic visual target C is recognized in the visual field.

  The visual function of the retina can be scanned by repeating similar processing. When the dynamic visual target moves to the right end, the visual field inspection for that row ends, and when the button or the space key is pressed, the visual target appears from the left end of the next lower row, and the visual field scan is continued. The entire field of view of one eye can be scanned by repetition.

  Since the central part of the visual field and the macular part have high spatial resolution, the distance between the static visual target and the dynamic visual target when the button or the space key is pressed becomes short. In the fovea portion, the distance between the static visual target and the dynamic visual target is the shortest (see 5 in FIG. 1). On the display, the degree of the distance between the static visual target and the dynamic visual target is converted into a color shading and displayed as a shading two-dimensional scan diagram. Scaled display such as bright color when the distance between the two points of static and dynamic targets is long, dark color when the distance between the two points of static and dynamic targets is short I do. In the present invention, it is possible to measure with an accuracy of about 10 minutes or less, such as the total visual field effective photoreceptor density of one eye, but the inspection time is shorter than the inspection accuracy.

  Since humans gain sight through the optic nerve and brain, the ophthalmoscope does not know the state of higher visual function than the retina. If you are not a subject, you will not know the state of the dark spot. Even the test subject cannot recognize the shape and size of the dark spot around the visual field other than the fixed viewpoint and the central part of the visual field (see the part 4 where the dark spot and the blind spot are connected in FIG. 1). The present invention makes it possible to faithfully reproduce the dark spot and blind spot shapes that can be transmitted from the retinal photoreceptor cells to the visual cortex on the display. The retina in the eye, the area where the optic nerve does not function effectively (see dark spot 1 in FIG. 1), the area where visual function is reduced (see area 15 where the pyramidal cells or optic nerve axons in FIG. 1 are slightly impaired). ) Can be reproduced on a display like a map.

  Since the dynamic target is moved at a constant speed in the horizontal direction, it is possible to perform a test that is not affected by the judgment of the dark spot area of the subject and prejudice, and the objectivity of the test result recorder is maintained. It is. In a conventional dynamic perimeter, the dynamic target moves in a random direction, and spatial resolution does not appear in the inspection result. However, in the present invention, the dynamic target is moved horizontally and the inspection result is horizontal. Accumulated information on directional spatial resolution, enabling two-dimensional scan display.

  Intuitively understand the severity of the dark spot area relative to the fixation point and the macular area. As a result of the measurement, the difference in resolution of the visual field was expressed in detail as a two-dimensional scan, and the shape of the visual field defect portion (see 1 in FIG. 1) and the shape of the blind spot were displayed on the computer screen. The blind spot diameter enlarged state (see 2 in FIG. 1) due to the optic nerve depression or the like can be displayed. In addition to visual field defects and dark spots, areas that have slightly damaged pyramidal cells, reduced cone density, or reduced cone function can be displayed on the display as a two-dimensional scan on a gray scale. (See 15 in FIG. 1).

  The state of vision loss is difficult to explain to others, but it can be intuitively explained by the present invention.

  Since the present invention can detect a spatial resolution of about 10 minutes or less, it cannot be found in a conventional perimeter having a defect that a field defect within a few degrees cannot be detected such that a connection portion from a dark spot to a blind spot becomes gradually thinner. A glaucoma characteristic of a dark spot can be detected (see 4 in FIG. 1). Can detect and display the relationship between Bjerrum area dark spots and blind spots such as glaucomatous visual field defects and horseshoe-shaped dark spots.

  It is possible to detect and display the shape of the visual field defect field such as laser retinal property in the field far from the fovea.

  Inspection can be speeded up by using dynamic targets for static targets. Humans can respond quickly to moving objects. Dynamic visual targets are less susceptible to visual familiar afterimages than static visual targets, and the examination time can be shortened by reducing the subject's confirmation judgment time for the appearance of the visual target. Due to the high sensitivity of the dynamic target to the human static target, the subject will not respond to the reappearance of the dynamic target even after a certain amount of areas, such as dark spots, where the spatial separation ability is low. High speed response is possible (see 16 in FIG. 1). The horizontal movement of the dynamic target having a certain distance, its speed, etc. considerably reduce the monotony of the conventional perimeter.

  By using two points of a static visual target and a dynamic visual target alternately and continuously, recognition of the dynamic visual target by the subject becomes a central work for the off-center visual field, and the examination time is shortened. On the other hand, for the macular region, which is an important part in vision, static target recognition becomes a central task, and the degree of visual function can be inspected in detail slowly. Parts with low spatial resolution can be inspected at high speed by high-speed processing, and parts with high spatial resolution can be inspected at low speed.

  When recognizing two points of the dynamic target relative to the static target, or when recognizing the movement of the dynamic target in the field of view, pressing the button or space key pressed the button or space key to the fixation target part A mark indicating that is displayed. Since the subject can confirm that the button has been pressed at a high speed, the inspection processing efficiency increases. The confirmation mark is partially overlapped and displayed on the fixation target, and the fixation target is partially lost to increase the accuracy of the subject's fixation on the fixation target (see 17 in FIG. 5). Increase scanning accuracy.

  The fixation point fixation target increases the fixation point gaze degree of the subject by performing high-speed two-color alternating blinking (see 25 in FIG. 3). With a non-flashing fixation target such as a conventional perimeter, it is difficult to stare due to a visual afterimage.

  Since the subject performs fast flashing fixation point fixation target fixation, there is a case where the dynamic target cannot be recognized even if it reaches the right end of the display (see 27 in FIG. 6). In such a case, the dynamic optotype reaches the right edge of the display, the inspection of that line is in the end state, and a mark indicating that it is waiting for the inspection of the next lower line (see 26 in FIG. 6). .) Are displayed on the fixation target in the fast blinking fixation point. After the subject recognizes the mark on the fixation point fixation target portion, the test can be started on the next lower row by pressing the button or the space key. Alternatively, the examination can be restarted after a short break.

  After the field-of-view inspection is completed, the above mark is displayed, and each time the button or space key is pressed to start the next-line inspection, the result of the visual field function two-dimensional scan up to that point However, only the inspected area from the bottom line is displayed instantaneously. The subject can hardly recognize what the scan results are due to fixation target gaze, but can recognize a very bright display near the dark spot and blind spot area, so It has an effect of greatly reducing, and can prevent a decrease in visibility due to a familiar afterimage (see FIG. 2). By bringing about a change, the subject's concentration can be maintained. The subject can roughly recognize the progress of the examination by peripheral vision. It is also possible to adjust so that the scan results are not sequentially displayed on the display during the inspection by the program. The program can be adjusted in various ways such as the size of the target. The target movement speed and direction can be adjusted in various ways by the program. The program allows various adjustments such as display display, full field-of-view space resolution scan tone, and color tone (see FIGS. 8 and 9).

  Since the inspection method of the present invention is simple, it is possible to easily experience visual field inspection and observation of blind spots at home. By visualizing the visual field state of the subject at home, explanation of the visual field state of the subject can be facilitated. Moreover, since the inspection output result is beautiful, it is possible to relax by performing a visual field inspection for a certain period of time and looking at the output.

Program A which shows in detail the shape of the visual field defect area, blind spot, etc. on the display by actively selecting and limiting the range to be inspected (see FIG. 9 for the visual field inspection result by program A). In addition, the dynamic visual target that moves according to the computer settings is moved actively when the subject recognizes the change in visibility, and the visual function status is increased at a high speed by accurately determining the position of the visibility change. The program B is capable of extracting the contour and displaying the inspection result on the display (see FIG. 10 for the visual field inspection result by the program B).

  The present invention relates to a perimeter that attempts to illustrate a visual field function state in detail on a display to a degree that cannot be realized by conventional perimeter inspection, and a method for extracting only the outline of the visual field function state. The present invention relates to a perimeter that attempts to show the outline of a dark spot blind spot on a display at a high speed that cannot be realized with this perimeter.

  Conventional perimeters include the following (for example, see Reference 1).

  Goldmann perimeter, 510 type (1945), 940 type (1967), Tubinger perimeter (1957), Octopus perimeter (1976).

A conventional perimeter will be described. Goldmann perimeter is the first brightness perimeter and manual simultaneous recording type. Target brightness is 4 to 60 types, target viewing angle is 6 types, viewing angle field and background brightness can be adjusted. The disadvantage is that it is impossible to measure the center within 5 °. Tubinger perimeter (1957) is the first practical static perimeter. Dynamic visual field, color field, flicker field, etc. can be measured. Manual simultaneous recording type. Target luminance 80 types, fixation target luminance 100 types, color 5 types, background luminance 6 types. Central and external visual acuity measurements. The disadvantage is that it is difficult to move the target, and it is difficult to adjust the target, fixation target, and background light. Octopus perimeter (1976) is the world's first fully automatic static perimeter.

  The basic perimeter currently in practical use has not been improved since 40 years ago. Since the perimeter used in the current visual field inspection is a manual simultaneous recording type and manual dynamic visual field inspection, the accuracy of the inspection is not constant over the entire visual field. In addition, the test result is influenced by the recording method of the target of the recorder, and the test result record does not faithfully reflect the dark spot, blind spot shape, and mutual positional relationship of the subject. If the recorder hears from the subject about visual field impairment, the test results are affected. The entire field of view cannot be inspected uniformly. The degree of visual impairment at the dark spot for the macular region, which is important for central vision, is not intuitively reflected in the test results. Areas with slightly damaged pyramidal cells are not displayed in the test results. Inspection time is long. Since the test is monotonous with a constant period, an erroneous response to the visual target due to the periodic habituation of the subject may occur. The shapes of dark spots and blind spots detected for manual recording are very rough, and the figure of the test result is considerably different from the actual shape of the dark spots and blind spots for the subject.

  In the fully automatic static visual field inspection used in the current visual field inspection, the space separation ability visual acuity of several degrees or less cannot be inspected in order to shorten the entire visual field inspection time. The perimeter used in the current visual field inspection shortens the inspection time for measuring the entire visual field, so whether it is manual static visual field inspection, fully automatic static visual field inspection, manual dynamic visual field inspection, It does not have the ability to detect areas with reduced visual function within a few minutes.

However, the connection area from the dark spot to the blind spot, which is said to be characteristic for glaucoma dark spots and macular neovascularization dark spots, may be about 2 minutes (see 4 in Fig. 9), and the spatial separation is about several degrees or less. It is not detected by a conventional perimeter that has no function.

  In the case of the current fully automatic dynamic perimeter, the test results do not reflect the shape of any of the subject's dark spot blind spots. However, the inspection time is very long. Since the examination is very monotonous and repeats a certain period, the subject is likely to make an error response due to the periodic learning effect of the appearance of the stimulus, familiarity, and the like.

  Performing visual function visual field inspection for all fields of view is extremely unrealistic with conventional perimeters because the test subject is a human being, causing fatigue due to the length of the test time and inability to stare due to afterimages. Is. Therefore, the visual field inspection method capable of high-speed inspection while being a very detailed visual field inspection, and the output method of inspection results were computerized by a program.

  Program A that allows the visual field function state to be illustrated in a very detailed manner on the display by a method of selecting and limiting the visual field area to be examined in detail. In Program A, it is possible to actively pre-select areas where the visual field inspection is desired. If it is a partial area of the field of view, it can be inspected in great detail, and since it is a partial area, the inspection time can be reduced. When selecting a range for performing visual field inspection in detail, a figure of visual field inspection result by contour extraction type high-speed visual field inspection program B (see FIG. 10), or a full-field retinal function scanning program submitted on June 18, 2007 The inspection result diagram (see FIG. 11) can be referred to.

  The program A represents the static target by computer control in the visual field inspection range that is actively selected in advance, and moves the horizontal right target sequentially as soon as the subject's response to the target is obtained. A very detailed visual function state of the visual field retina of about 5 minutes or less can be displayed in a beautiful figure on the display (see FIG. 9).

  On the other hand, in the case of the program B that realizes the contour extraction type high-speed visual field inspection, the subject passively uses a dynamic target moving at a speed set in advance by a computer for high-speed processing. The subject aims at speeding up the visual field inspection by adopting a method in which the subject is required to respond only to the dynamic visual target moving in the horizontal right direction when the change in the visibility is recognized. It is easy for the subject to recognize the appearance of discontinuous positions of the visibility on the dynamic target moving in the horizontal right direction.

  In Program B, the subject first performs blinking fixation point fixation target gaze with one eye. When the subject continues to press the target right direction moving button →, the dynamic target appears from the left end of the display at a speed set in advance in the computer, and moves to the right at a certain high speed. The subject responds actively only when he / she recognizes a discontinuity in visibility. Sensitivity to human discontinuity is sensitive. In order to extract a shape contour such as a dark spot blind spot more accurately, the subject is required to actively search for a position where the target cannot be recognized.

  Unless the change is recognized in the visibility, the subject keeps pressing the right direction movement button → and does not respond one by one, so the examination time can be shortened. However, since the dynamic target moves at a relatively high speed, it takes a little time for the subject to recognize the discontinuity in the sensitivity to the target and to make a response to release the right button. However, the dynamic visual target is converted to a static visual target after moving slightly to the right from the visibility change position. The subject can easily recognize that he has gone too far to the right of the visibility change position. After such recognition, the subject can accurately determine the discontinuity of the visibility while actively moving the visual target around the discontinuity of the visibility with the left movement button ← or the right movement button → Press to record the position.

  This is a method in which the subject's target recognition confirmation trap time is converted into the subject's active position adjustment time, and the subject's judgment trap time that occurs in order to correct the target recognition is zero, resulting in visual field inspection. The process is speeded up and at the same time the accuracy of contour extraction is achieved. Since it is possible to inspect the subject while adjusting the position by recognizing that the target has been moved too far in the right direction, etc., the response delay during the contour extraction by the subject, etc. The error of the recording position due to can be reduced to zero.

  After the visibility change position is determined and recorded, the subject does not record the visual field state by pressing a button inside the dark spot blind spot area or the like, so the examination time is greatly shortened. In such a visibility-invariant field, the subject simply presses the right movement button → to the next position where the change in visibility can be recognized. When the inspection of one line is completed, for example, the dynamic visual target exceeds the right end of the display, the dynamic visual target appears from the left end of the display of the next lower line by computer control, and the visual field inspection of that line is continued. By repeating the same process, the program B makes it possible to extract the contour of the visual field visibility changing area at a very high speed.

 The method of the present invention for the program B is applicable not only to the field of view but also to general searches for extracting features of interest from a wide range at high speed.

  The visual field inspection result is easy to understand and interesting because it is a feature contour extraction type (see FIG. 10). By appropriately setting the size of the target, the moving speed, etc., it is possible to realize a one-eye full-field inspection time of 5 minutes or less.

  It can be corrected in the reverse direction and can respond accurately. Because it is a high-speed inspection, passive high-speed target movement, and active adjustment target movement mixed type, there is no fatigue. No monotonous reaction error occurs. The inspection result can detect the glaucomatous feature of the dark spot (see 4 in FIG. 10).

  If it is only the outline, the visual field inspection result diagram of the high-speed visual field inspection program B (see FIG. 10) is a very detailed visual field inspection result diagram by the program A (see FIG. 9), submitted on June 18, 2007 It is equivalent in accuracy to the visual field inspection result diagram (see FIG. 11) by the full visual field retinal function scanning program.

  In addition, in the program B, it is possible to observe a state where the shape of the geometric target passing through the blind spot is distorted. Observe blind spot diameter, blind spot depression, etc. The degree of the effect of dark spots on reading can be shown on the display by using letters as targets. High-speed extraction of the outline of the function of the fovea is possible on the display. By adjusting the target, it is possible to extract the contours of areas with reduced function density of cone cells.

  In the program B method, it is possible to extract a contour of a field that recognizes some feature of the retinal function.

  Since humans get sight with the optic nerve and brain, they cannot know the state of dark spots unless they are subjects. Even in the test subject, the shape and size of the dark spot around the visual field other than the fixed viewpoint and the central part of the visual field cannot be recognized at all (4 in FIG. 9 and 4 in FIG. 10). According to the present invention, by virtue of the method of actively selecting the area to be inspected, the visual acuity functional state is shown in detail on the display, and the visual acuity functional state is adjusted at high speed by passively moving and adjusting the visual target. The program B shown in the extraction and display makes it possible to faithfully reproduce the dark spot and blind spot shapes that can be transmitted from the retinal photoreceptor cells to the visual cortex. Each of the programs of the present invention displays the retina in the eye and the area where the optic nerve does not function effectively (see dark spot 1 and blind spot 2 in FIG. 9, dark spot 1 and blind spot 2 in FIG. 10) like a map. You can reproduce it clearly.

  By the method of actively selecting the area to be inspected, the program A whose visual visual function state is shown in detail on the display can detect the visual function lowered area (see 15 in FIG. 9). The visual field functional state is extracted at high speed by passively moving and adjusting the visual target, and the visual function lowered area can be detected by selecting the color tone and flicker degree of the visual target in the program B shown in the display.

  All of the programs of the present invention enable a test that is not affected by the judgment and preconception of the recording person on the dark spot area of the subject, and the objectivity to the recording person of the inspection result diagram is maintained.

  The result of the visual field inspection is shown in detail on the display by the program, and the shape of the visual field defect part (see 1 in FIG. 9 and 1 in FIG. 10) and the shape of the blind spot (see 2 in FIG. 9 and 2 in FIG. 10). Displayed on the computer screen. The degree of seriousness in the position of the dark spot area with respect to the fixation point and the macular portion can be intuitively understood (see 14 in FIG. 9 and 14 in FIG. 10). It is possible to display in detail such as the blind spot diameter enlarged state due to optic nerve depression.

  The state of vision loss is difficult to explain to others, but can be intuitively explained by the present invention (see FIGS. 9 and 10).

  In the present invention, the program A which shows the visual field function state in detail on the display by the method of actively selecting the area to be inspected can detect a very fine spatial resolution, so that the connecting portion from the dark spot to the blind spot is gradually increased. A glaucoma characteristic (refer to 4 in FIG. 9) of about several minutes, which cannot be detected with the accuracy of a conventional perimeter, can be detected. It is possible to detect and display the relationship between Bjerrum area dark spots and blind spots such as glaucomatous visual field defects and horseshoe-shaped dark spots in great detail.

  The visual field inspection result diagram of the present invention and program A displays the bending state of the dark spot area (see 1 in FIG. 9) in detail, which is very helpful when estimating the origin of the dark spot. The result of the inspection of the conventional basic perimeter does not show the degree of bending of the dark spot area.

  According to the present invention, the visual field functional state is extracted at high speed by passively moving and adjusting the visual target, and the program B shown in the display is darkened by appropriately setting the size and moving speed of the visual target. The contour of the glaucoma characteristic of about several minutes, which cannot be detected with the accuracy of the conventional perimeter, such that the connecting portion from the point to the blind spot becomes gradually thinner can be detected (see 4 in FIG. 10). It enables high-speed inspections such as the relationship between dark spots and blind spots in the Bjerrum area, such as glaucomatous visual field defects and horseshoe-shaped dark spots, and detailed contour display at a very high speed.

  In the present invention, the program B method makes it possible to extract the contours of the dark spots in detail at high speed and display them on the display (see 1 in FIG. 10). It is very helpful when estimating the origin of dark spots. The result of the inspection of the conventional basic perimeter does not show the degree of bending of the dark spot area.

  According to the present invention, the method of actively selecting the field to be inspected, the program A showing the visual visual function state in detail on the display is very detailed in the field defect field such as laser retinal property in the field far from the fovea. The shape can be detected and displayed on the display.

  According to the present invention, a visual field functional state is extracted at high speed by passively moving and adjusting a visual target, and a program B illustrated on a display is used to form a visual field defect region shape such as a laser retina in a region away from the fovea. It is possible to display the contour of the detection at a very high speed.

  Program A can shorten the inspection time by actively selecting the inspection range. On the other hand, in the contour high-speed extraction type program B, a region where the retinal visual function is impaired or the feature to be observed is not discontinuous can be subjected to passive high-speed visual field inspection by using a high-speed dynamic visual target, impaired retinal visual function, Alternatively, in areas where the features to be observed are discontinuous, a dynamic visual target can be converted into a static visual target, and active visual field inspection can be performed at a low speed. Since the subject responds only to the contour portion, the examination time is greatly shortened.

  In the case of visual field inspection by Program A. Execute program A. A button for selecting the inspection range appears. When you press the button, a fixation target for fixation point gaze appears on the display. While looking at the fixation target position, you can choose the range of visual function inspection. Move the cursor to the position of the upper left corner where you want to perform visual field inspection, press the left mouse button, move the cursor in that state, and when you reach the position of the lower right corner of the area to be examined, click the left mouse button The range of the visual field inspection is determined by releasing. The determined visual field inspection range is displayed for a moment.

  After that, the fixation target (14 in Fig. 9) starts two-color alternating fast flashing to facilitate gaze during the examination time. The subject blocks the other eye and stares at the fast blinking fixation target with two colors.

  The static target that the subject should recognize appears from the upper left of the visual field inspection range. If the static target is recognized in the field of view, the subject presses the right arrow → button. If the static target cannot be recognized in the field of view, the subject presses the left arrow ← button. Regardless of which button is pressed, Program A moves the static target slightly in the horizontal right direction under computer control. If the static target is recognized in the field of view, the subject presses the right arrow → button. If the static target cannot be recognized in the field of view, the subject presses the left arrow ← button. Subject continues the same process.

  When the static target reaches the right end of the inspection range, the static target appears at the left end of the next row under computer control, and the visual field inspection for that row continues. Each time the subject presses the left arrow ← during the visual field examination, a record of the position of the static target that the subject could not recognize is accumulated.

  When the examination of the entire selected area is completed, all the positions on the display of static targets that the subject could not recognize in the field of view are displayed. In the background, the fixation target and the range of visual field inspection are displayed, so you can easily understand the severity of the dark spot with respect to the fovea.

Illustrations such as dark spots and blind spots in the test results are so detailed that they are beautiful, and are useful because they can estimate the visual field cells and optic nerve function status. You can clearly see the enlargement and distortion of blind spots (see Fig. 9).

  Program B, on the other hand, is a multi-functional program that can observe various visual field functions. When program B is executed, the fixation target blinks in two colors alternately at high speed to enable long-term observation, and other static targets appear.

  When you press the right mouse button, you can set various settings such as the speed of moving the static target, the size of the static target, the color of the static target, the degree of static target blinking, and the background color. The static target moves as a dynamic target at the speed set in those directions by holding down the up / down / left / right arrow buttons.

  While staring at the fixation target, the subject can recognize the visual field loss state, blind spot position, etc. with the dynamic target. A variety of target symbols can be entered using the right mouse button.

  If you use a geometric symbol as a dynamic target, you can observe how the geometric shape is distorted around the blind spot. You can observe the appearance of a geometrical figure as if it was sucked into a blind spot with central visual acuity. If you move the dynamic target horizontally above the fixation target, you can see how the dynamic target moves in a spiral, and know that two photoreceptor clusters are converged in one ganglion. can do. If the character is a dynamic target, you can know the degree of character recognition in the macula.

  The feature of Program 2 as a visual field inspection is the button at the bottom of the setting item by the right mouse button (see 50 in FIG. 10). When the button below the complementary color button is pressed, two-color alternating fast flashing fixation target and static target appear. Move the cursor to the upper left of the display and press the left mouse button. The static target moves to that position and appears.

  Attempts to check the functional status of one-eye full-field vision at high speed. The subject gazes at the fixation target.

  If you keep pressing the right arrow button, the static target will start moving dynamically at the set moving speed. When the subject recognizes the change in the visibility with respect to the target, release the right arrow button and use the left and right arrow buttons to determine the position of the visibility change while the subject is actively adjusting, Press once. Visibility change position can be determined accurately. Next, do not press the space bar until the visibility changes.

  Until the position where the visibility changes, press the right arrow button again to increase the inspection speed by using a dynamic target. When one line of inspection is finished, computer control begins to inspect the line below it.

  By repeating, it is possible to extract the contour of the visibility change area at high speed.

  When the inspection of all fields of view is completed, the inspection result blinks on the display.

  If the size and movement speed of the target are set appropriately, the entire field of view for one eye, the shape of the blind spot, and the contour extraction can be realized in less than 5 minutes.

  When the visual field sensitivity does not change, the subject passively performs high-speed processing by using a computer-set dynamic visual target. The sensitivity change position is reconfirmed accurately, and the position is recorded by pressing the space key. After recognizing the change in visibility, pressing the right arrow button to respond to similar reactions, such as pressing the space key, dynamically uses the target to speed up the examination. When the subject recognizes a change in visibility with respect to the target, the subject will go back a little, etc. to actively reconfirm the visibility change position and record the location by pressing the space key. The contour extraction result is very accurate.

  Since the program was created and checked with Windows95, the moving speed of the dynamic target may need to be adjusted if the processing speed is about Windows95.

  The fixation point fixation target increases the fixation point fixation degree of the subject by performing two-color alternating high-speed blinking (see 14 in FIG. 9 and 14 in FIG. 10). With a non-flashing fixation target such as a conventional perimeter, it is difficult to stare due to a visual afterimage.

  Since the inspection method of the present invention is simple, it is possible to easily experience visual field inspection and observation of blind spots at home. By visualizing the visual field state of the subject at home, explanation of the visual field state of the subject can be facilitated. In program B, various features of retinal vision function and blind spot can be observed. Further, in both cases of program A and program B, since the inspection output result is beautiful, it is possible to relax by performing a visual field inspection for a certain time and looking at the output.

A program is created in Hsp language.

1 dark spot 2 blind spot 4 dark spot connected to blind spot, glaucomatous or neovascularization dark spot 14 foveal or fixation target that blinks rapidly in two colors 15 pyramidal cells or optic nerve axons are slightly impaired Territory 50 Contour extraction type high-speed visual field inspection program

In the conventional visual field inspection, the shape of the blind spot in the inspection result diagram is very rough, so that detection of glaucoma features and the like may fail, and the inspection time is very long.

Program A allows the inspection range to be selected and limited in advance, so that a very detailed visual function test can be performed in a relatively short time. As a result, the shape of the scotoma is clearly displayed on the display. Enable. The program A can clearly detect glaucoma characteristics for the blind spot of the dark spot that could not be detected by the conventional perimeter, and can intuitively show it on the display. On the other hand, the program B requires the subject to respond actively only when recognizing a change in the visibility of the dynamic target moving in the horizontal right direction. As a result, the extraction of the shape of the blind spot and the detection of the glaucoma characteristic for the blind spot of the dark spot were successfully detected at a high speed of about 10 minutes.

A perimeter that displays a spatial resolution capability distribution graph, a perimeter that intuitively expresses the degree of visual field loss, and a perimeter that rapidly extracts the contours of the retinal visual function change area in two dimensions.

The present invention is a perimeter (see program 1; see FIG. 18) that is intended to display a frequency distribution graph relating to spatial resolution, and a perimeter (see program 2) that is intended to intuitively express the degree of visual field loss in% display. (See Fig. 20) In addition, we will increase the accuracy and intelligibility of the shape of the extracted contour by extracting the contour of the visual field retinal function changing region at high speed and combining the two-dimensional scan. (See program 3; see FIG. 21).

  Conventional perimeters have very rough inspection results such as dark spots and blind spots, are not intuitive, and may fail to detect glaucomatous features. However, the time required for the inspection is very long. In addition, the degree of visual field loss cannot be intuitively expressed.

  Conventional perimeters have very rough inspection results such as dark spots and blind spots, are not intuitive, and may fail to detect glaucomatous features. However, the time required for the inspection is very long. In addition, the degree of visual field loss cannot be intuitively expressed.

  Since the program 2 of the present invention is a method for displaying the ratio of the visual field defect area to the visual field inspection area as a percentage, it is possible to quantitatively evaluate the degree of obstacle due to visual field defect during sentence recognition.

  Since the retinal area important for text reading is the fovea, it is a method that limits the examination range very much. Therefore, short-time measurement evaluation with an inspection time of about 2 minutes is achieved. (See FIG. 20).

The program 3 of the present invention dynamically moves the visual target from the upper left corner of the display in the horizontal right direction while fixing the center of the display, and determines the visibility change position with respect to the visual target in units of rows. After scanning the vertical contour of the visibility change area by scanning, the target is dynamically moved vertically upward from the lower left corner of the display, the visibility change position is determined in units of columns, and the same processing is performed to the right. This is a method of scanning and extracting the horizontal contour of the visibility change area by repeating in the direction (see FIG. 21).

In the case of the present invention program 3 .
The output to the display is a method of synthesizing the vertical and horizontal contours, and as a result, the contour of the visibility change area scans only the vertical contour by dynamically moving the target in the horizontal right direction. It becomes clearer (see FIG. 21) than when extracted (see FIG. 15 and FIG. 17).

In the case of the present invention program 3 .
Because the horizontal direction of the target is scanned and the vertical contour of the visibility change field is scanned and then the horizontal profile of the target is changed by the vertical movement of the target and the results of both are combined. The contours of dark spots, blind spots, etc. are very clear and can be extracted at a high speed of 10 minutes. (See FIG. 21.)

  The spatial separation ability frequency distribution graph in the program 1 of the present invention is a visual function degree distribution (see FIG. 19) spatially arranged and expressed in the two-dimensional direction in the full-field retinal function scan result diagram. The order is to be rearranged from the viewpoint of resolution (see 1 and 2 in FIG. 18). By observing the same distribution from two different viewpoints, it can be estimated whether the distribution generation process of one (for example, the full-field retinal function scan result diagram) is plausible and appropriate. Further, the display of the spatial separation ability frequency distribution graph of the contralateral visual field may provide a control distribution for examining the visual field function state with respect to the examination-side visual field spatial separation ability frequency distribution graph (see FIG. 14).

  The program 2 of the present invention can perform a very detailed visual visual function test in a relatively short time by actively selecting and limiting the inspection range in advance (see 200 in FIG. 20). Can be clearly displayed on the display (see 205 in FIG. 20). The program of the present invention can clearly detect glaucoma characteristics (see 26 in FIG. 16) with respect to the blind spot of the dark spot which could not be detected by the conventional perimeter, and can intuitively show it on the display.

  Since the program 2 of the present invention is a method for displaying the ratio of the visual field defect area to the visual field inspection area as a percentage, it was possible to quantitatively evaluate the degree of failure due to visual field defect during sentence recognition. (See 200 and 202 in FIG. 20).

In the case of the present invention program 2.
With familiar% display, the state of visual field loss can be intuitively understood as an area.
(See FIG. 20).

In the case of the present invention program 2.
Since the retinal area important for text reading is the fovea, it is a method that limits the examination range very much. Therefore, short-time measurement evaluation with an inspection time of about 2 minutes was achieved.
(See 200 and 202 in FIG. 20).

In the case of the present invention program 2.
The seriousness of the position of the dark spot area relative to the fixation point and the fovea is metrically displayed as a percentage and can be explained intuitively. (See 200 and 202 in FIG. 20.)

In the case of the present invention program 2.
In addition to text reading / recognition recognition, a visual field inspection range such as a dark spot to a blind spot can be selected in advance, and the degree of visual field defect area relative to the inspection area can be evaluated quantitatively and objectively.
(See 205 in FIG. 20.)

  It is impossible with a conventional perimeter to quantitatively evaluate the visual field defect area with respect to the visual field inspection range. (See Program 2 of the present invention. See FIG. 20).

The program 3 of the present invention requires the subject to respond actively only when recognizing a change in the visibility of the dynamic visual target moving in the horizontal right direction and later in the vertical upward direction. The outline of a shape such as a blind spot can be extracted at high speed, and as a result, the shape of the dark spot blind spot is extracted (60 and 66 in FIG. 21), and the glaucoma characteristics of the dark spot with respect to the blind spot (see 62 in FIG. 21). We succeeded in high-speed detection with an inspection time of about 10 minutes.

In the case of the program 3 of the present invention, the method of responding only to the position where the subject has recognized the change in the visibility in the visual field inspection is not limited to the visual field, and a search for extracting features of interest from a wide range at high speed. This is a generally applicable method. Part of a method that attempts to actively change the information processing speed adaptively to the characteristics of the target by processing the essential part at a low speed and processing the non-essential part at a high speed. It is. (See FIGS. 20, 21, 15, and 17.) The importance of this method stems from the phenomenon that it is not so easy for humans to flexibly convert their information processing speed according to the target.

In the case of the present invention program 3 .
In the case of the feature outline extraction type, the visual field inspection result diagram is easy to understand and interesting for human recognition characteristics (see FIGS. 17 and 15). By appropriately setting the size of the target, the moving speed, etc., it is possible to realize a one-eye full visual field inspection time of 5 minutes or less (see FIG. 17 and the like).

In the case of the present invention program 3 .
Because the horizontal direction of the target is scanned and the vertical contour of the visibility change field is scanned and then the horizontal contour of the target is changed by the vertical movement of the target and the results of both are combined. The contours such as dark spots and blind spots can be extracted very clearly at a high speed of 10 minutes. (See FIG. 21).

In the case of the program 1 of the present invention.
It became possible to make the computer a perimeter and a retinal visual function tester immediately. The inspection result becomes a beautiful scan diagram with sequential two-dimensional gray scale display and displayed on the display during the inspection, reducing the monotonicity of the visual field inspection. Since the inspection method uses two visual targets alternately, the inspection speed is dynamically increased in the off-center visual acuity, while the inspection details are statically increased in the macula. Generate scan diagrams by using the horizontal and vertical inspections in an accumulative manner. Since an objective and detailed examination is possible compared with the conventional perimeter, a glaucomatous dark spot that cannot be detected by the conventional perimeter can be detected (see 26 in FIG. 16). The visual function level of the visual function lowered area is also displayed in a scannable manner in an intuitively understandable manner (see 25 in FIG. 16).

In the case of the program 1 of the present invention.
After executing the visual field retinal function scanning program, the frequency distribution with the spatial resolution as the class can be displayed on the display as a columnar graph. The frequency distribution graph is displayed in the order of the spatial resolution. From the graph, it can be seen that the central visual acuity is restricted by the visual information processing capacity (see 1 in FIG. 18), and the external visual acuity is restricted by the retinal area (see 2 in FIG. 18). Due to the limitation of visual information processing capacity and the optimized balance of maximal spatial resolution with respect to the retinal area, both sides of the frequency distribution graph have an increasing exponential function on the left side and a decreasing exponential characteristic on the right side. It can be seen that the resolution distribution graph shows a single peak shape. In particular, in the central visual acuity, the frequency of a class having a large spatial separation power is remarkably reduced, and the frequency is expressed in a columnar graph in a state where the visual information processing capacity is strongly restricted.

In the case of the program 1 of the present invention.
If the examination-side visual field frequency distribution graph is displayed on the opposite side frequency distribution graph as a background, it is possible to infer a spatial resolution class in which the visual function in the examination-side visual field is degraded or the visual field is missing. . (See FIG. 14). A spatial resolution class that constitutes a visual field defect area such as a dark spot appears as a frequency in a class having a low spatial resolution (see 5 in FIG. 18).
In the case of the program 1 of the present invention.
The spatial resolution frequency distribution graph tries to reorder the visual function distribution that is spatially ordered and expressed in the two-dimensional direction in the full-field retinal function scan result diagram from the viewpoint of spatial resolution in the one-dimensional direction. Is. By observing the same distribution from two different viewpoints, it was possible to infer whether the distribution generation process of one (for example, full-field retinal function scan result diagram) was plausible and appropriate. Moreover, the display of the spatial separation ability frequency distribution graph of the contralateral visual field sometimes provided a reference distribution for examining the visual field functional state with respect to the inspection side visual field spatial separation ability frequency distribution graph.

Since Program 1, Program 2 and Program 3 are all described and confirmed in Windows 95, it is necessary to adjust the target moving speed or fixation target blinking speed appropriately in other environments where the processing speed is different. It is thought that there is.
For program 2.
Regarding the method of selecting the corresponding visual field inspection range in measuring the degree of visual field defect impairment for reading / recognition of sentences in% units, for example, a character permutation similar in character shape in terms of spatial separation, such as yellow English, For example, the subject can actively move it left and right and up and down, and the range in which the subject can distinguish yellow and English is determined as the examination range. How to select the inspection range from the foveal point of view.
Alternatively, it is possible to select a horizontal inspection range and a vertical inspection range by moving the target target in the horizontal direction to the left and right for horizontal writing and the vertical movement for vertical writing. In that case, the vertical inspection range and horizontal inspection range are determined by the font size of the target. In this method, it is considered that the degree of visual field deficit with respect to reading comprehension is expressed with considerably different numbers in the case of reading comprehension for horizontal writing and for reading comprehension of vertical writing. This is because the traveling of the optic nerve axon has horizontal directivity. (See 200 and 202 in FIG. 20).
The importance of reading range recognition for horizontal writing and vertical writing in the horizontal and vertical directions, respectively, is symmetrical from the left and the right from the viewpoint of the retention of memory in human reading. I don't think so. (See 202 in FIG. 20).
The program 3 uses a certain size of the target, so that the subject can determine the position of the target when the target is missing due to darkness, blind spot, etc. If it is determined in advance whether to determine the visibility change position, it is considered that the determination time for determining the visibility change position in the target recognition can be considerably reduced.
For example, FIG. 21, FIG. 15, FIG. 17, and the like show the test results when the subject has determined in advance that the visual loss is about 50% due to the visual field defect field to be the visibility change position. FIG.
In the programs 1 and 2 with small targets, the determination time for the degree of target loss was almost zero when determining the visibility change position, and thus it was not necessary to perform such consideration.
However, in visual field inspection, learning effects regarding the shape of dark spots and blind spots, which are accumulated according to the frequency of inspection and are effective for the accuracy of the inspection, can occur, and various features of visual function can be extracted. The subject can select such as the degree of target defect.
Further, when the degree of target defect to be set as the visibility change position is clearly determined in advance, the visibility change position with respect to the dynamic target is not equal in the horizontal and vertical scans as detected in FIG. Since there is a portion (see 62 and 66 in FIG. 21), it is possible to accurately observe a phenomenon in which the peripheral visual field such as the blind spot position is sequentially moved by increasing the visual field inspection time.

Accurate position adjustment is a method in which the subject actively moves the target at a static low speed.

202 indicates that the visual field defect area was 25% of the inspection range 202 The degree of obstacle to reading comprehension of the dark spot running in parallel with the optic nerve axon, etc.
In contrast to the 15.9% quantitative evaluation of the visual field loss for horizontal writing,
The quantitative evaluation of the visual field loss degree for vertical writing is calculated to be 25.5%. The dark spot of such a shape can be interpreted as having an obstacle to the recognition of vertical writing than horizontal writing. You can select a certain area as the inspection range,
Intuitively calculate the degree of visual field loss relative to the inspection area,
The result can be shown on the display

  In the conventional perimeter, the inspection result diagram is very rough, so detection of glaucoma features and the like may fail, and the inspection time is very long. In addition, the degree of visual field loss cannot be expressed intuitively.

  Since the ratio of the visual field defect area to the visual field inspection area can be displayed in%, the degree of obstruction caused by visual field defect during sentence recognition can be evaluated quantitatively. The retinal area that is important for text reading is the foveal region, and the examination range can be very localized, so that a short-time measurement evaluation with an examination time of about 2 minutes is achieved. Because the horizontal direction of the target is scanned and the vertical contour of the visibility change field is scanned and then the horizontal contour of the target is changed by the vertical movement of the target and the results of both are combined. The contours of dark spots, blind spots, etc. are very clear and can be extracted at a high speed of 10 minutes. The display of the spatial resolution power distribution graph of the contralateral visual field provides a control distribution for examining the visual field functional state for the examination visual field.

A program that can accurately measure and display the impact level of visual field loss on character recognition in%

  The present invention relates to a perimeter program that is designed to intuitively display a visual field visual impairment level in character recognition on a computer display as a percentage.

  Conventional perimeters cannot intuitively evaluate the subject's visual field defect level using numbers.

  Further, the conventional perimeter does not attempt to measure and measure the seriousness of the visual field defect for the subject and the influence of the visual field defect on the character recognition of the subject.

It is difficult to display the subject's visual field defect level in terms of how to set the inspection visual field range.
When calculating the ratio of the visual field defect area to the examination area, the dark spot area is included in the visual field defect area, but there are cases where it is not desired to include the blind spot area with individual differences.
Since it is affected by the position of the dark spot and the area of the blind spot, it is difficult to obtain a number representing a visual field defect level that is stable enough to be compared among a plurality of subjects.
This is because the ratio of the visual field defect area such as a dark spot to the inspection area changes depending on the selection of the inspection area.

The present invention is a system in which a field of view having a spatial separation ability equal to or higher than the spatial separation ability of a visual target is used as an inspection range.
It is possible to obtain a number representing a visual field defect level that is stable enough to be compared among a plurality of subjects.
The ratio of the area of the visual field defect portion such as a dark spot to the area of the inspection range having a spatial separation ability equal to or higher than the spatial separation ability of the target is displayed on the display.
Actually, since the visual field spatial resolution decreases concentrically from the fixed viewpoint in the radial direction, the character target is circulated around the fixed viewpoint in a circular orbit to detect a certain spatial resolution range in the visual field. Is appropriate.

In the program of the present invention, characters are used to detect the spatial resolution in the field of view, but symbols having an appropriate spatial resolution can also be used.
This is a method for detecting a character recognition range in a visual field easily and at a high speed, and a method for detecting a visual field exceeding the spatial resolution at a simple and high speed.

In order to facilitate gaze, the visual field inspection range is determined by a method in which a target composed of letters, symbols, etc. is dynamically orbited slowly and circularly around a fixation target straddling two colors alternately.
First, the character target is around the fixed viewpoint.
The subject increases or decreases the orbital radius of the visual target. This is a method of setting a radius at which the visual target cannot be clearly recognized as a character on the resolution as the radius of the visual field inspection range.
The selected circular visual field inspection range is a very important visual field for character recognition of the subject.
Perform a detailed visual field inspection for the area.
The visual field inspection is a method for confirming and recording the visibility of the dot-like target and covering the inspection range by slightly moving the target sequentially. If the target moving speed is reduced to some extent, it is possible to reduce an error reaction when the subject confirms the target.
Since the inspection range is limited from the viewpoint of character recognition, the inspection can be performed in a very short time but in detail.
In addition, when the target for setting the inspection range only moves linearly, the position of the dark spot hinders recognition of the target, and settings such as the upper and lower limits of the inspection range from the viewpoint of character recognition are equivalent for the subject. It can be difficult.
However, the inspection range can be easily determined in a very short time by using a method of changing the orbital radius of the dynamic character target.

  It is possible to accurately display the level of influence of visual field loss on character recognition for the subject.

  The program according to the present invention can detect a visual field range having a spatial separation enough to recognize a character at high speed, and the ratio of a visual field defect portion area such as a dark spot with respect to the visual field impairment level as a percentage in terms of character recognition. Intuitive numbers can be displayed on the display.

The ratio of the visual field defect area to the inspection area selected by the program method is
Very consistent value.
The ratio of the visual field defect area to the visual field inspection range set by the dynamic character target that performs the circular orbit can be displayed numerically by intuitive%.

The degree of obstacles due to visual field defects such as dark spots for character recognition can be displayed numerically on the display.
The accuracy of the inspection can be confirmed by the consistency of the inspection of several degrees.

  It is easy to understand because the visual field defect state can be displayed graphically on the display.

  It is a program that selects the inspection range from the viewpoint of character recognition, performs visual field inspection at high speed, and displays the visual field defect degree and visual field defect state clearly and in detail on the display.

If the resolution is reduced to some extent, an inspection time of 5 minutes can be achieved, but the resolution is sufficiently practical.
A very detailed examination is possible by reducing the size of the target.
By changing the visual target from the viewpoint of spatial resolution, the inspection visual field range can be expanded to cover the dark spot potential visual field range.

  Even if the radius of the circular orbit followed by the target for detecting the visual field important for reading comprehension changes, the CPU performs arithmetic processing to control the target display so that the angular velocity of the target is constant. Also good.

A visual field area with a spatial resolution sufficient for character recognition can be detected at high speed, and the percentage of the visual field defect area such as a dark spot is intuitively displayed on the computer display as a visual function impairment level in character recognition. Programs that can be displayed.
In order to facilitate gaze, the visual field inspection range is determined by a method in which a target composed of letters, symbols, etc. is dynamically orbited slowly and circularly around a fixation target straddling two colors alternately.
First, the character target is around the fixed viewpoint.
The subject increases or decreases the orbital radius of the visual target. A method of setting the radius of the visual field inspection range as the radius that prevents the subject from clearly recognizing the target as a character on the resolution.
The selected circular visual field inspection range is a very important visual field for character recognition of the subject.
Perform a detailed visual field inspection for the area.
Since the inspection range is limited from the viewpoint of character recognition, the inspection can be performed in a very short time but in detail.
In addition, when the target only moves linearly, the position of the dark spot becomes an obstacle, and setting the upper limit or lower limit of the inspection range from the viewpoint of character recognition may be quite difficult for the subject.
However, the inspection range can be easily determined in a very short time by using a method of changing the orbital radius of the dynamic character target.
The result is a very constant value.
If the resolution is reduced to some extent, an inspection time of 5 minutes can be achieved, but that resolution is practical enough.
The ratio of the visual field defect area to the visual field inspection range set by the dynamic character target that performs the circular orbit can be displayed numerically by intuitive%.
The amount of obstacles due to visual field defects such as dark spots for character recognition can be displayed on the display.
The accuracy can be confirmed by the consistency of several-degree inspection.
3. A visual field inspection range setting method from the viewpoint of character recognition of a program capable of displaying a visual field defect level in character recognition according to claim 2.

A very detailed examination is possible by reducing the size of the target.
It is easy to understand because the visual field defect state can be displayed on the display.
A program that allows you to select the inspection range from the viewpoint of character recognition, perform visual field inspection at high speed, and display the visual field defect level and visual field defect state clearly and in detail on the display.
A program that can display the severity of visual field loss for subjects from the viewpoint of character recognition.

About the target used when selecting the inspection range from the viewpoint of character recognition,
The target symbol may be changed to another symbol from the viewpoint of spatial resolution.

The inspection range may be selected from the viewpoint of color recognition.
The visual target may be based on the visibility to the color.
A range in which the color of the visual target can be determined may be a target visual field for visual field inspection.

By increasing the radius of the target in the orbit,
The inspection range may be expanded to cover the dark spots.

The conventional perimeter does not have a method for setting the character recognition range easily and at high speed.
The conventional perimeter does not display a ratio regarding the degree of visual field loss.
The degree of visual field loss is not quantitatively intuitive.

The invention program is written in Hsp language.
The program is written in Windows95.
The angular velocity of the target that orbits was adjusted at a processing speed of about Windows95.

Conventional perimeters do not attempt to detect the severity of subjects with visual field defects, the effects of visual field defects on character recognition, and the like. In addition, the visual field defect level of subjects cannot be evaluated numerically by% or the like.

The visual field inspection range is determined by changing the radius of the dynamic character target in the orbit around the fixation target. The ratio of the visual field defect area to the range can be numerically displayed by intuitive%. This is the degree of seriousness for character recognition of visual field loss for the subject. Since the inspection range is limited from the viewpoint of character recognition, an inspection time of 5 minutes can be achieved. A program that allows you to select the inspection range from the viewpoint of character recognition, perform visual field inspection at high speed, and display the degree of visual field loss and visual field defect state neatly in detail on the display.

A program A, a program B, a program C, and a program D of the present invention that can detect the position of the blind spot in the visual field of both eyes and the size of the blind spot at high speed and display them on the display.
The left-right difference in blind spot diameter can be calculated and displayed on the display in an intuitive manner, for example, the blind spot size of the right eye is 1.06 times the left eye (see 2 in FIG. 27). Program A and program B.
The position of the detected blind spot and the change of the blind spot diameter scale with respect to the examination time can be sequentially displayed on the display (see FIG. 26).

  The present invention detects the position of the blind spot in the visual field of both eyes and the size of the blind spot at a high speed, displays it on the display, the left-right difference of the blind spot diameter, for example, the blind spot size of the right eye is 1.06 times the left eye, etc. As can be said, it is possible to calculate and display on the display in an intuitive manner (see 2 in FIG. 27), and to change the position of the detected blind spot and the change in the diameter size of the blind spot with respect to the examination time. The present invention relates to an optic disc characteristic high-speed detection program for sequentially displaying on a display (see FIG. 26).

The conventional perimeter does not specialize in blind spot characteristic high-speed detection, and does not have a function that can measure and display the blind spot diameter difference.
Further, the conventional perimeter does not have a function capable of recording the variation of the blind spot position blind spot diameter within the visual field inspection time.

The conventional perimeter does not specialize in blind spot characteristic high-speed detection, and does not have a function that can measure and display the blind spot diameter difference.
Further, the conventional perimeter does not have a function capable of recording the variation of the blind spot position blind spot diameter within the visual field inspection time.
In the case of the optic disc characteristic high speed detection program of the present invention.
In the present invention program A, program B, program C, and program D, the blind spot position of both visual fields and the size of the blind spot of the subject detected at high speed by the circular orbit are displayed on the display side by side (see FIG. 27). .).
In the programs A and B of the present invention, the left-right difference in blind spot diameter is calculated and displayed on the display in an intuitive manner, for example, the blind spot size of the right eye is 1.06 times the left eye. (Refer to 2 in FIG. 27.)
The programs A and B of the present invention intuitively compare the states of the left and right visual fields with respect to the blind spot on the display using approximate contour diagrams (see 30 and 40 in FIG. 27) and numbers (see 2 in FIG. 27).
The degree of left / right asymmetry and left / right divergence (see FIG. 27) is information related to retinal stress, glaucoma, etc. in both the blind spot position and blind spot diameter.
The purpose of the program D of the present invention is to sequentially display the change of the position of the detected blind spot and the diameter scale of the blind spot with respect to the examination time on the display (see FIG. 26).

Blind spot inspection method of the present invention program A, program B, program C, program D.
For detecting the position of the blind spot, an * mark target (see 25 in FIG. 29) and a dynamic target (see 14, 22 in FIG. 29) that performs two inner and outer circular trajectories around the * mark are used. .
The blind spot diameter detection is a method in which two inner and outer circular orbit targets (see 14 and 22 in FIG. 29) centering on the mark * are adjusted while changing the trajectory radius.

For example, when testing is detected from the blind spot of the right eye field.
The left eye field is blocked and the central fixation target is fixed with the right eye.
The subject moves the green * mark near the fixation target to the right using the arrow keys.
The subject presses the enter key at a position where the green * mark cannot be seen.
Determine the position of the right eye blind spot. The green * mark disappears.
The fixation target will continue to be displayed.
The subject continues to stare at the fixation target (see 6 in FIG. 29).
Next, two circular orbits appear on the inner and outer sides around the purple mark (see 25 in FIG. 29) (see 14, 22 in FIG. 29).
The purple * mark appears at the center position of the blind spot detected by the previous green * mark.
The inner circular orbit (see 22 in FIG. 29) is a green target that dynamically performs a circular orbit.
The outer circular orbit (see 14 in FIG. 29) consists of a red visual target that dynamically performs a circular orbit.

When trying to conduct a more accurate inspection.
In order to detect the blind spot position more accurately, the purple * mark (see 25 in FIG. 29) is set to appear at a position slightly away from the previous green * mark.
If the subject can recognize the purple * mark in the peripheral visual field, use the arrow keys to move the purple * mark to within the blind spot.

  When moving the purple * mark, in the present invention program A, program B, program C, and program D, the two inner and outer circular orbits centered on the purple * mark (see 25 in FIG. 29) are also the same distance and in the same direction. This is a method of moving (see 14, 22 in FIG. 29).

Two circular orbits (see FIGS. 14 and 22 in FIG. 29) have a function of easily speeding up the approximate diameter detection of blind spots (see 30 and 40 in FIG. 27).
The detection error of the blind spot diameter can be limited as compared with the case of using one circular orbit.
The blind spot contour radius detection error can be limited within a radial distance difference between the two inner and outer circular orbits.
For example, when using only the inner green circle orbit.
When adjusting the green circle orbit within the blind spot area, even if the green circle orbit radial distance is made too short by pressing the B key too much, the subject cannot recognize the degree.
This is because the green circle orbit is already within the blind spot area.
However, as in the present invention program A, program B, program C, and program D, a red circular orbit (centered on the same purple mark *) is located outside a certain distance from the green circular orbit (see 22 in FIG. 29). In the case where there is 14) in FIG. 29, if the radius is made too short, the outer red circular orbit (see 14 in FIG. 29) enters the blind spot area. At that time, since the subject can recognize the defect of the red circular orbit in the field of view, the subject can recognize that the radius has been reduced too much.
The subject can adjust with the H key to increase the radius.

The blind spot inspection method of the program A, program B, program C, and program D of the present invention is as follows. Reduce orbital radius.
However, the position of the outer red circular orbit (see 14 in FIG. 29) is adjusted by adjusting the position and moving radius by pressing the B key or H key so that the subject can see around the blind spot area.
The B key or H key has a function of reducing and increasing the radius of the inner and outer double circular orbits (see 14 and 22 in FIG. 29) by the same distance.

The subject adjusts the inner green orbit (see 22 in FIG. 29) within the blind spot area and the outer red orbit (see 14 in FIG. 29) outside the blind spot area.
The blind spot radius detection error can be limited to the radial distance difference between the outer circular track and the inner circular track.

  For more detailed inspection, more accurate blind spot position, and blind spot diameter approximation, set the trajectory radius to B key or H so that the inner green circle orbit (see 22 in FIG. 29) remains slightly around the blind spot. Adjust with key. Adjust the green dynamic target around the blind spot so that the subject can recognize it.

If the green distribution recognized around the blind spot has a deviation depending on the direction, it is adjusted using an arrow key or the like so that the green distribution is as small as possible.

The green distribution (see 22 in FIG. 29) by the circular orbit dynamic target visible around the blind spot is uniformly distributed, and the corona green distribution with respect to the circumference of the blind spot is averagely balanced. It can be detected.
Thereafter, the trajectory radius is further reduced and adjusted until the green color (see 22 in FIG. 29) is not visible.
The outer red circular orbit (see 14 in FIG. 29) is visible around the blind spot.
Adjust the position with the arrow keys so that the corona-shaped red circular orbit is as homogeneously distributed as possible around the blind spot.
Adjust the trajectory radius by B key or H key.
This is a method capable of accurately detecting the blind spot diameter.

As a result of the inspection, the left and right blind spot states can be displayed in parallel on the left and right sides of the fixation target center on the display.
The left-right difference in the position of the blind spot and the left-right difference in the blind spot diameter scale are intuitively displayed on the display (see FIG. 27).

  When changing the size of the target for carrying out the circular orbit (see 30, 40 in FIG. 27), the influence of the size of the target on the detection blind spot area increase / decrease can be seen.

The programs A and B of the present invention can calculate the diameter ratio of the left and right blind spot approximate contours (see FIG. 27).
The difference in the size of the left and right blind spots can be evaluated numerically (see 2 in FIG. 27).
For example, if the right eye blind spot is larger, the program of the present invention calculates the right blind spot diameter / left blind spot diameter.
If the result is 1.06, the diameter of the right blind spot is 1.06 times the diameter of the left blind spot.
The right blind spot is 6% larger than the left blind spot.
The left-right difference in the blind spot diameter can be expressed intuitively by numbers (see 2 in FIG. 27).
In the left and right blind spot comparison, relative glaucomatous abnormalities are grasped.
The left-right blind spot comparison represents the effects of intraocular pressure, axial length, stress on the retina, and adverse effects on visual function (see 2 in FIG. 27).

In the present invention program A, program B, program C, and program D, the blind spot area contour is approximated by a circular orbit.
This is because the blind spot diameter can be detected at a high speed.
When a blind spot is approximated from the inside by a green circular orbit, the blind spot minimum area is extracted when a blind spot that is not completely circular is approximated from the inside by a circular orbit.
When a blind spot is approximated from the outside by a red circular orbit, the maximum blind spot area is extracted when a blind spot that is not completely circular is approximated from the outside by a circular orbit.
In the program B of the present invention, the detected inner green circle orbit and outer red circle orbit can be collectively displayed on the display as a result of such a blind spot inspection (see FIG. 28).

  The deviation of the bi-circular orbit represents the degree of deviation of the blind spot area from the circular orbit.

To inspect the degree of deviation of the blind spot area from the circular orbit, first move the inner green circle orbit completely within the blind spot area. To be precise, the corona green distribution seen around the blind spot is adjusted with the arrow key, B key or H key so as to make the circumference uniform.
Thereafter, the subject adjusts the trajectory radius using the B key or the H key so that the red circular trajectory is completely outside the blind spot area.

However, there is distortion in visual recognition around the blind spot.
The phenomenon may represent distortion such as unevenness of the retina.
May represent glaucomatous characteristics.
Program B showing the area with distortion around the blind spot on the display, which represents the area with distortion around the blind spot.
To do so, first move the inner green circle orbit so that it is completely within the blind spot area.
To be precise, the position is adjusted while making the corona green distribution visible around the blind spot uniform.
Thereafter, the subject adjusts the trajectory radius so that the red circular trajectory is completely outside the blind spot area.
However, the trajectory radius is increased by the H key to such an extent that the subject can recognize the red circular trajectory as a complete circular trajectory (see 36 in FIG. 28).
The subject can recognize a complete circular orbit because the visual recognition is distorted around the blind spot, so the red circle orbit is not recognized as a circular orbit immediately around the blind spot, and the trajectory is distorted or a trajectory defect occurs. This is because there is a region (see 62 in FIG. 28).

When the visual field inspection is continued with the fixation target gaze, the position of the blind spot always moves little by little (see 5 in FIG. 26).
The size of the blind spot always changes little by little (see 15 in FIG. 26).
The program D of the present invention which can display the movement and change state on the display.
In order to reflect the temporal movement of the blind spot position and the temporal change of the blind spot diameter scale on the display, the inspection speed is increased. Do some blind spot tests to some extent.
However, it is accurate because it uses two inner and outer circular orbits.
Easily detect blind spot position diameter.

For example, when detecting the degree of blind spot change with respect to the visual field inspection time of the right eye.
The subject blocks the left eye field and stares at the central fixation target with the right eye.
Move the green * mark target in the center fixation target to the subject's blind spot area by moving it to the right side with the arrow keys.
Press enter when the green * mark is not visible in the field of view. The green * mark disappears.
The fixation target continues to be displayed (see 6 in FIG. 29).
The subject continues to stare at the fixation target.
A purple * mark target (see 25 in FIG. 29), and two inner and outer circular orbit targets (see 14, 22 in FIG. 29) appear.

When the blind spot position change is to be detected accurately, the program C
A purple mark * (see 25 in FIG. 29) is set so as to appear in the vicinity of the fixation target (see 6 in FIG. 29).
The subject must move the purple mark (see 25 in FIG. 29) from the vicinity of the fixation target (see 6 in FIG. 29) to the blind spot at every examination.
In this method, the center position of the blind spot detected by the subject is not affected by the test result regarding the blind spot position so far.

However, when paying attention to the time change of the blind spot, the present invention program D is used.
From the viewpoint of reducing the examination time, the purple * mark (see 25 in FIG. 29) appears approximately at the position of the blind spot detected by the examination results so far, and is a method of reducing the position adjustment time by the subject.
However, the inner and outer circular orbits (see 14 and 22 in FIG. 29) are displayed by increasing the moving radius to some extent at each inspection.
Since the radius is increased to the extent that the test subject can recognize the inner green circular orbit and the outer red circular orbit, the inner green circular orbit (see 22 in FIG. 29) is completely located within the blind spot area each time the examination is performed. Adjust the trajectory radius.
When the trajectory radius is reduced by the B key, the radius is reduced and the position is adjusted while adjusting the position so that the corona green distribution is uniform around the blind spot, and attention is paid to the corona balance of the green distribution around the blind spot.

For example, if the blind spot tends to move to the ear side with the examination time, the green target on the circumference of the blind spot part circle immediately before the green circle orbit enters the blind spot when the trajectory radius decreases with the B key. For example, the corona distribution is recognized as being biased toward the nose.
In that case, the circular orbit is moved to the ear side by an arrow key or the like.
Average the green corona balance around the blind spot.
In this method, the green corona distribution recognized by the subject around the blind spot is adjusted so that it is as homogeneous as possible around the circumference.
A system that adjusts to create a corona with a green orbit that is homogeneous around the circumference of the blind spot.
This is a method of adjusting the trajectory radius so that the inner green circle orbit becomes invisible due to the blind spot, but the outer red circle orbit appears homogeneous around the blind spot.
Using the B key or H key, the subject determines the blind spot position and blind spot radius.
Press enter.
By repeating the same examination, the program D of the present invention can show the time transition of the blind spot position and blind spot diameter on the display (see 5 and 15 in FIG. 26).
Since the results of repeated inspections of the blind spot position and blind spot diameter in the visual field are overwritten on the display, the temporal transition state of the blind spot position is well understood (see 5 in FIG. 26).
The display color of the blind spot outline is changed with time (refer to 5 and 15 in FIG. 26).
The blind spot position moves, for example, in the horizontal ear direction in proportion to the length of the examination time (refer to 5 and 15 in FIG. 26).
However, fluctuations may occur in the moving direction (see 5, 15 in FIG. 26).
The detected blind spot diameter may also fluctuate depending on the length of the examination time (refer to 5 and 15 in FIG. 26).
However, in the overwriting, the previous blind spot position motion described in duplicate on the display cannot be grasped. In order to improve the state where the fluctuation is not reflected on the display when the movement of the blind spot position fluctuates not only in one direction but also in the opposite direction, the change of the blind spot position and the blind spot radius with time is displayed in an intuitive graph.
It is the graph display which makes time a coordinate axis.
The blind spot position and blind spot radius are graphs that collectively display in the direction perpendicular to the time coordinate axis (see 15 in FIG. 26).
It has been observed that the detected blind spot position is horizontally moved sequentially in proportion to the time (see FIGS. 5 and 15).
However, there are cases where the blind spot position does not move in proportion to time and is not flexible.
The blind spot diameter may increase with time (see 5, 15 in FIG. 26).
Phenomenon displayed on the display by the program D of the present invention, such as the degree of blind spot position flexibility with respect to time and the degree of change in blind spot scale (see 5, 15 in FIG. 26) are stress on the fundus or visual function. May represent the characteristics of

  In the present invention program A, program B, program C, and program D, the blind spot position of both visual fields and the size of the blind spot of the subject detected at high speed by the circular orbit could be displayed on the display side by side (see FIG. 27). .)

  In the programs A and B of the present invention, the left-right difference of the blind spot diameter can be calculated and displayed in an intuitive manner, for example, the blind spot size of the right eye is 1.06 times the left eye. (See 2 in FIG. 27.)

The programs A and B of the present invention can intuitively compare the state of the left and right visual fields related to the blind spot with an approximate contour diagram (see 30 and 40 in FIG. 27) and numbers (see 2 in FIG. 27) on the display.
The degree of left / right asymmetry and left / right divergence (see FIG. 27) is information related to retinal stress, glaucoma, etc. in both the blind spot position and blind spot diameter.

  In the program D of the present invention, the position of the detected blind spot and the change of the blind spot diameter with respect to the examination time can be sequentially displayed on the display (see FIG. 26).

Two circular orbits (see FIGS. 14 and 22 in FIG. 29) have a function of easily speeding up the approximate diameter detection of blind spots (see 30 and 40 in FIG. 27).
The detection error of the blind spot diameter can be limited as compared with the case of using one circular orbit.
The blind spot contour radius detection error can be limited within a radial distance difference between the two inner and outer circular orbits.

As in the present invention program A, program B, program C, and program D, a red circle orbit (FIG. 29) centered on the same purple * mark outside the green circle orbit (see 22 in FIG. 29) to some extent outside. 14), if the radius is too short, the outer red circular orbit (see 14 in FIG. 29) enters the blind spot area. At that time, since the subject can recognize the defect of the red circular orbit in the field of view, the subject can recognize that the radius has been reduced too much.
The subject can adjust with the H key to increase the radius.

  The subject adjusts the inner green orbit (see 22 in FIG. 29) within the blind spot area and the outer red orbit (see 14 in FIG. 29) outside the blind spot area.

  The blind spot radius detection error can be limited to the radial distance difference between the outer circular track and the inner circular track.

For more detailed inspection, more accurate blind spot position, and blind spot diameter approximation, set the orbital radius to the B key or H so that the inner green circle orbit (see 22 in FIG. 29) remains slightly around the blind spot. Adjust with key. Adjust the green dynamic target around the blind spot so that the subject can recognize it.
If the green distribution recognized around the blind spot has a deviation depending on the direction, it is adjusted by an arrow key so that the green distribution is as small as possible.

The green distribution (see 22 in FIG. 29) by the circular orbit dynamic target visible around the blind spot is uniformly distributed, and the corona green distribution with respect to the circumference of the blind spot is averagely balanced. It can be detected.
Thereafter, the trajectory radius is further reduced and adjusted until the green color (see 22 in FIG. 29) is not visible.
The outer red circular orbit (see 14 in FIG. 29) is visible around the blind spot.
Adjust the position with the arrow keys so that the corona-shaped red circular orbit is as homogeneously distributed as possible around the blind spot.
Adjust the trajectory radius by B key or H key.
This is a method capable of accurately detecting the blind spot diameter.

  When changing the size of the target for carrying out the circular orbit (see 30, 40 in FIG. 27), the influence of the size of the target on the detection blind spot area increase / decrease can be seen.

The programs A and B of the present invention can calculate the diameter ratio of the left and right blind spot approximate contours (see FIG. 27).
The difference in the size of the left and right blind spots can be evaluated numerically (see 2 in FIG. 27).
For example, if the right eye blind spot is larger, the program of the present invention calculates the right blind spot diameter / left blind spot diameter.
If the result is 1.06, the diameter of the right blind spot is 1.06 times the diameter of the left blind spot.
The right blind spot is 6% larger than the left blind spot.
The left-right difference in the blind spot diameter can be expressed intuitively by numbers (see 2 in FIG. 27).
In the left and right blind spot comparison, relative glaucomatous abnormalities are grasped.
When a blind spot is approximated from the inside by a green circular orbit, the blind spot minimum area is extracted when a blind spot that is not completely circular is approximated from the inside by a circular orbit.
When a blind spot is approximated from the outside by a red circular orbit, the maximum blind spot area is extracted when a blind spot that is not completely circular is approximated from the outside by a circular orbit.
In the program B of the present invention, the detected inner green circle orbit and outer red circle orbit can be collectively displayed on the display as a result of such a blind spot inspection (see FIG. 28).
When the visual field inspection is continued with the fixation target gaze, the position of the blind spot always moves little by little (see 5 in FIG. 26).
The size of the blind spot always changes little by little (see 15 in FIG. 26).
The program D of the present invention which can display the movement and change state on the display.
In this method, the green corona distribution recognized by the subject around the blind spot is adjusted so that it is as homogeneous as possible around the circumference.
A system that adjusts to create a corona with a green orbit that is homogeneous around the circumference of the blind spot.
This is a method of adjusting the trajectory radius so that the inner green circle orbit becomes invisible due to the blind spot, but the outer red circle orbit appears homogeneous around the blind spot.
The program D of the present invention was able to show the time course of the blind spot position and blind spot diameter on the display (see 5 and 15 in FIG. 26).
It has been observed that the detected blind spot position is horizontally moved sequentially in proportion to the time (see FIGS. 5 and 15).
Phenomenon displayed on the display by the program D of the present invention, such as the degree of flexibility of blind spot position movement with respect to time and the degree of change in blind spot scale (see 5, 15 in FIG. 26) May represent a feature.

The present invention program A, program B, program C, and program D can select the detection blind spot diameter error degree by changing the radial distance difference of the inner and outer circular orbits.
The target can be selected to an appropriate size for the program.
Invention program A, program B, program C, program D.
It is best from the left and right blind spot comparison to conduct the blind spot inspection with the distance from the right eye to the display and the distance from the left eye to the display as equal as possible.
Invention program A, program B, program C, and program D are created at an information processing speed of about Windows95.

2 Calculate and display the left / right blind spot diameter ratio 5 Shift of blind spot position and fluctuation of blind spot diameter in visual recognition that occurs with increasing test time 6 Fixation target staring at the subject 14 Red circular orbit extracting the maximum area blind spot contour 15 Vertical coordinate axis is time , Horizontal coordinate axis represents blind spot position blind spot diameter Vertical top direction is temporally ahead 22 Green circle trajectory extracting the minimum area blind spot contour 25 Detecting blind spot position * mark 30 Blind spot contour extracted when the target is small 36 Circular orbit without distortion in visual field 40 Blind spot contour extracted when the target is large 62 Peripheral area around the blind spot that causes distortion in visual recognition

The conventional perimeter does not specialize in high-speed detection of the blind spot characteristic, and does not have a function capable of measuring and displaying the blind spot diameter difference. Further, the conventional perimeter does not have a function capable of recording the variation of the blind spot position diameter within the visual field inspection time.

The program ABCD of the present invention enables high-speed detection within a few minutes of the blind spot characteristic by using a method using two circular orbit targets having a gap. The result is accurate by a method in which the subject adjusts the circular orbit position and radius so that a corona-like distribution consisting of a circular orbit green target that can be recognized by the subject around the blind spot is distributed as uniformly as possible around the circumference. In the program AB of the present invention, the left-right difference in the blind spot diameter can be displayed on the display in an intuitive manner, for example, the blind spot size of the right eye is 1.50 times the left eye. Useful. In addition, the program D of the present invention succeeded in displaying on the display the state where the position of the blind spot and the diameter scale are constantly changing as the inspection time increases.

The present invention program allows a subject to select a field inspection range in a limited manner while viewing his or her visual field defect state on the display, and to increase the resolution of the field scan while shortening the inspection time.

  The present invention allows a subject to select a visual field inspection range in a limited manner while viewing his / her own visual field defect and visual function deterioration state on the display, and to increase the resolution of visual visual function scanning while reducing the inspection time. The present invention relates to a program designed to synthesize and use high-resolution visual field visual function scan results obtained in a short time by a range-limited station.

The conventional perimeter is not a method in which the subject selects the visual field inspection range.
The visual field inspection time with a conventional perimeter is very long and very monotonous.
The result diagram of the conventional perimeter test is quite rough and does not faithfully reflect the shape of the dark spot blind spot visually recognized by the subject, and may fail to detect the glaucomatous characteristics of the subject.

The conventional perimeter is not a method in which the subject selects the visual field inspection range.
Since the conventional perimeter does not limit the inspection range, sufficient resolution cannot be obtained in the inspection result diagram.

Since the subject can hardly visually recognize the position of his / her own dark spot and blind spot in addition to the center portion of the visual field, it is difficult for the subject to select the examination range with a purpose from the viewpoint of the visual field portion of interest.
It was not easy to select the inspection range quickly and accurately.

  The present invention allows a subject to select a visual field inspection range in a limited manner while viewing his / her visual field deficit state and visual function deterioration state on the display, to increase the resolution of visual visual function scanning while reducing the inspection time, and This program aims to synthesize and use high-resolution visual field visual function scan results obtained by short-term inspections based on limited inspection ranges and accumulated by multiple inspections.

The program of the present invention is a method in which the display is alternated in two colors at appropriate time intervals in order to allow the subject to recognize his or her own visual field loss and visual function deterioration state.
When two-color display of display colors is performed alternately at appropriate time intervals, areas with reduced visual function such as dark spots and blind spots with enlarged diameters cannot follow the changes in display color over time and remain as afterimages. Therefore, we decided to use the phenomenon that the subject recognizes the dark spot, the enlarged diameter part of the blind spot, etc. as a color defect on the display.
Using red-orange-black color, which is difficult to follow visually, the subject can see the shape of the visual function-decreasing region such as the blind spot blind spot on the display, including the peripheral visual field, in considerable detail.

The program of the present invention can move the fixation target, and the subject can move the visual field of interest near the center of the display. This is useful when the field of interest is recognized at the edge of the display.

  In order to record the visual field state of the subject visually recognized as a color defect on the display to the computer in a reproducible manner with high resolution, the subject performs visual visual function scanning using a static dynamic diopter. Use.

In the program of the present invention, the subject can move the fixation target while looking at his / her visual field defect state on the display, and can move the examination target visual field to the center of the display, This is useful when the inspection object does not fit in the display.
The inspection range for visual visual function scans is that the subject sees a display color defect that represents the subject's visual field defect on a display that alternates between two colors, and is interested in the display color defect, such as dark spots and dark spots. The connection part from a point to a blind spot is selected by surrounding it with an intuitively easy-to-understand "" mark.
The inspection range is a rectangle, and the subject determines the upper-left corner point with the “mark”.
Next, the lower right end point of the inspection range is determined by “”.

In the program visual field visual function scan of the present invention, the subject stares at the fixation target with the eye on the examination side.
The fixation target is a fixed type, and the static dynamic diopter scans the visual field visual function in the horizontal direction.
When one line scan is completed, the next line scan is started.
By sequentially repeating the row scan, the program of the present invention can show the visual function level and the spatial resolution level of the examination range selected by the subject on the display.
The computer can convert the distance between the targets that allow the subject to spatially separate and recognize the two targets on the display, and the computer can display the result on the display.
For example, when the spatial separation ability is high, the display is bright, and when the spatial separation ability is low, the display is dark.
When the movement of the target is recognized in the visual field, the subject presses the space key.
Alternatively, the visual function of the visual field is sequentially scanned by a method in which the subject presses the space key at the time of separating and recognizing the two visual targets.
While performing visual visual function scanning without interruption in the horizontal direction, the static visual target is detected as long as the subject's ability to react to the visual target recognition is established in order to detect the spatial separation ability equivalent to character recognition and reflect it in the inspection result. Is set to a waiting time of about 0.5 s until the static target becomes the two targets of the dynamic target.

The program of the present invention that enables a subject to select a visual field inspection range while viewing his / her visual field deficit and visual function deterioration state on a display.
When two colors of display colors are displayed alternately at an appropriate time interval, areas with reduced visual function, such as dark spots and blind spots with enlarged diameters, cannot follow the change in display color over time, and the previous color remains as an afterimage. As a result, a dark spot, a blind spot diameter enlarged portion, and the like are recognized by the subject as a color defect on the display.
The method of the present invention program is particularly effective when the subject has glaucoma characteristics, when the retina has a pyramidal cell density reduced portion, or when the blind spot diameter is increased due to high myopia.
In order for a subject in such a state to recognize a visual field defect state, red-orange and black alternate display is particularly effective.

By the method of the present invention program, the subject can recognize the presence / absence of the visual visual function deterioration part and the visual field defect part from the display color defect, such as the shape and the positional relationship with the fixed viewpoint.
Using red-orange-black color, which is difficult to follow visually, the subject can see on the display the shape of the visual field deficit such as a blind spot and a visual function deterioration region on the display including the peripheral visual field in considerable detail.
The field of interest will be clear and the visual field functional scan inspection range can be selected very easily.

Since the subject can limit the examination range while viewing his / her visual field defect state on the display, the resolution of visual field visual function scanning can be increased while shortening the examination time.
Therefore, the shape of the dark spot blind spot, the shape of the connection part of the dark spot blind spot, and the like are reproduced and recorded very finely on the display.
The visual field functional scan uses a dynamic visual target to speed up visual field inspection.

In the program of the present invention, the high-resolution visual field visual function scan result diagram obtained in a short time by limiting the examination range can be used accumulatively.
It is possible to synthesize and display on the display a diagram of the results of short-time inspections performed in multiple times.
Short-term visual field inspection has less burden on the subject.
The subject can adjust the distance from the display to the subject by matching the composite view of the results up to the previous examination displayed on the display with the size and positional relationship of the blind spot visually recognized by the subject. Yes, and may reduce the composite deviation from subsequent inspection of the visual field visual function scan diagram.

The subject should block the visual field on the opposite side from the examination side.
First, when the program of the present invention is executed, the display starts red / orange / black / two-color alternate display.
The subject gazes at the fixation target with the eye on the examination side.
The subject can recognize his / her visual field defect and visual function deterioration part as display color defect and display color fading.
Depending on the degree of visual visual function degradation that the subject intends to extract on the display, the display colors of the two colors and the time interval of the alternate display can be set and adjusted.
The program of the present invention can move the fixation target.
The subject can easily check and check whether there is any other visual function degradation part such as a visual field defect in the visual field by moving the fixation target to various positions.
After moving the fixation target so that the visual field to be examined is approximately the center of the display, the subject presses the enter key, and determines the position of the fixation target for performing visual field visual function scanning.
Next, a “mark” appears near the display fixation target.
The subject continues to stare at the fixation target.
Next, the subject determines the visual field visual function scan inspection range.
The inspection range is a rectangle.
The subject moves the “mark” to the upper left corner of the field of view to be examined.
This is the determination of the start of the visual field visual function scan.
When you press the enter key, a “mark” appears on the display.
The test subject moves the “mark” to the lower right corner of the field of view to be examined.
When the enter key is pressed, the visual field function scan end is determined.
For example, when the subject wants to examine the dark spot part and the connection part from the dark spot to the blind spot, the test subject can recognize the dark spot part that can be recognized as a color defect on the two-color alternating display and the connection part from the dark spot to the blind spot. The inspection range is determined by selecting so as to enclose “”.
Next, a display appears that lets you choose between high-speed scanning and low-speed scanning.
A high-speed scan is used for a wide-range visual field inspection.
The dynamic target moving speed is set to twice that of the low-speed scan.
However, if you want to know the detailed spatial resolution structure of the local visual field inspection, visual field defect part or visual function loss part, choose low speed scan.
Visual visual function scanning uses both static visual targets and dynamic visual targets.
The dynamic target moves in the horizontal right direction at a constant speed.
When the subject can recognize the movement of the target in the field of view, or when the subject can recognize the two targets in the field of view, press the space key to This is a method for extracting spatial resolution.
When the subject presses the space key, the dynamic visual target becomes a static visual target, and the spatial resolution at that position of the visual field is recorded.
After a time interval of about 0.5 s, which allows the subject to react to changes in the target, the static target continues to be displayed and the dynamic target moves from the position to the right horizontal direction at a constant speed. Start.
The visual field functional scan has a rectangular inspection range.
After displaying the static target at the left end of the inspection range rectangle for a time that allows the subject to recognize the target, continue to display the static target, and scan the dynamic target from the position to the right. It is also possible to program as follows.
When the subject presses the space key when the movement of the dynamic target, or the static target and the two targets of the dynamic target can be recognized in the field of view, the static target until then disappears from the display. , Static target The distance between the dynamic targets is recorded on the display as the spatial resolution at that position of the visual field, and the dynamic target becomes a static target at the position where the space key is pressed. In this method, the dynamic target restarts moving to the right from the position after a fixed time of about 0.5 s when the subject can recognize the change of the target.
After completing the visual field visual function scan for the examination range selected by the subject and displaying the visual field visual function shading diagram of the examination result on the display, the program displays on the display whether or not to perform the visual field examination again. The subject can continue the visual field inspection. The subject can also select a range of different fields of view as the test object.
The visual visual function scan result diagram can be synthesized on the previous scan result diagram.
A full-field visual function scan gray scale can be synthesized from a local visual visual function scan gray scale obtained by a short-time examination with less burden on the subject.
It is also possible to program to store the visual field inspection results up to the previous time and to synthesize the current inspection results.

1 Dark spot 2 Blind spot 3 Visual function deterioration part 4 Dark spot blind spot connection part 5 which cannot be detected by conventional perimeter 5 Central fovea

Performing a full-field inspection at a high resolution is not feasible due to the long time required for the inspection, resulting in an afterimage familiar to the eye. However, since the subject cannot clearly recognize the visual field defect portion and the blind spot contour located in the peripheral visual field, it is difficult to select the visual field to be examined accurately and quickly.

The program of the present invention is a method in which the display colors are alternated between two colors of red, orange, and black at an appropriate time interval. In particular, a subject who has a blind spot enlargement clearly recognizes his / her visual function deterioration region as a display color defect. Therefore, it is possible to easily determine the inspection range. A visual function scan that is already a high-speed process by using a dynamic target can perform a higher-resolution scan from the viewpoint of inspection time by limiting the inspection range. In addition, a full-field visual function scan diagram can be synthesized from the accumulation of local visual function scan diagrams obtained in a short time.

A visual visual function level as a vertical axis direction with respect to the two-dimensional visual field is shown in a three-dimensional manner on a display with a height difference, and a program that allows the three-dimensional structure to be observed from all directions by rotating and translating it.

  The present invention provides a visual field visual function level as a vertical axis direction with respect to a two-dimensional visual field in a three-dimensional manner on a display with a height difference, and a perimeter capable of observing the three-dimensional structure from any direction by rotating and translating it. Regarding the program.

  Visual visual function level measured from the viewpoint of spatial resolution by a dynamic visual target etc. is shown in a three-dimensional manner on the display as a vertical axis direction with respect to the two-dimensional visual field. There is no perimeter program that makes it possible to observe the three-dimensional structure from the direction.

1 When the fixation target is located at the center of the display, the visual field range to be examined may not be able to fit in the display.

2. A fixation target that is always lit may reduce the concentration for the visual field test of the subject.
A fixation target that is always displayed at the same position may increase the monotonicity of the visual field inspection and the difficulty of fixation fixation due to visual familiarity.
It is considered that visual afterimages caused by always staring at the same position may negatively affect the visual sensitivity of the subject to the presented target.
Reduced subject concentration, as well as monotonicity of visual field testing, can increase false responses to target recognition.
Alternatively, when the subject's concentration with respect to the fixation target or the like decreases, the strictness of the response criterion used by the subject during target recognition may increase or decrease depending on the judgment of the subject.

3 If the response criterion of the subject with respect to the target is not clearly set in advance, the response criterion used by the subject may change over time during the examination.
The droop time required for response determination increases, which affects the inspection time, inspection result accuracy, and the like.

4 In the case of static visual target recognition or the like, it is considered that the time until visual familiarity is different between the central visual field and the peripheral visual field.
In particular, in the peripheral visual field from the outside of the central visual field, the target presentation time may affect the visual sensitivity of the subject.
Alternatively, the visual sensitivity of the subject may be affected by the length of time that the subject uses for target recognition.
It is considered that the same phenomenon occurs in the target presentation for the position on the retina where the visual visual function level is lowered.

5 Initial glaucomatous visual field features, retinal neovascularization visual field features, etc. are difficult to detect with a conventional perimeter with low resolution.
Normal-tension glaucomatous visual field features due to high myopia and the like are difficult to detect with a conventional perimeter with low resolution.
Since the conventional perimeter has a low resolution, it does not seem that the relationship between the visual field test result, the optic nerve axon running, and vascularity is strictly categorized.
As a result, there is a possibility that very precise information is not obtained from the visual field inspection result diagram.
In the conventional perimeter, precise information on the relationship between the optic nerve axon running and vascularity and the dark spot shape has not been obtained.
It is difficult to estimate in detail the optic nerve axon travel of the subject from the test result diagram of the conventional perimeter.
The conventional perimeter is not in a state where the cause can be estimated in detail from the shape of the dark spot in the initial stage.
With a conventional perimeter, detailed information about the dark spot and the optic disc connection cannot be obtained.

6 Three-dimensionalization of the visual field two-dimensional information by providing the spatial resolution information is performed by displaying the light and shade on the two-dimensional visual field, but there is a limit to the ability of a human to grasp such light and shade as a three-dimensional structure.
However, when the subject's spatial resolution state is to be observed as a three-dimensional structure perpendicular to the two-dimensional field of view, if the program is set to view from one direction, the field of view of the concave area farther away is projected by the three-dimensional convex area nearby. And the visual visual function state of the subject in that portion cannot be observed.

7 However, when the three-dimensional structure is to be observed from various directions by rotation about the coordinate axis, the three-dimensional structure often deviates from the center of the display and goes out of the display.
A method for positioning the observation object at the center of the display is required.

1 In the program A of the present invention, before starting the visual field inspection, the fixation target can be adjusted and moved in the horizontal direction so that the visual field range to be inspected can enter the display as much as possible.
Move the fixation target horizontally with the left and right arrow keys to the extent that the visual field to be inspected is at the center of the display, and then press the enter key to determine the horizontal position of the fixation target . The horizontal position is maintained until the visual field inspection is completed.

2 The fixation target of the program A of the present invention performs two-color alternate blinking at a high speed to a degree that can be recognized.
The fixation target of the program A of the present invention sequentially moves vertically downward in order to continue the visual field inspection at the horizontal position set before the inspection.
The program A of the present invention uses a dynamic visual target that is less monotonous than a static visual target as a presentation visual target.
The program A of the present invention measures the spatial separation in the horizontal direction of the display in the right direction without any spatial interruption, and measures the next line when the measurement for one line is completed. The subject responds following changes in the display display almost without any interruption in time, and the possibility of visual field inspection with less subjectivity of the subject increases.

3 The response criterion required by the program A of the present invention for the subject is a very simple criterion that the subject presses the space key when the movement of the target is recognized in the field of view.
The program A of the present invention measures the horizontal spatial resolution using only the dynamic visual target, but in order to measure the central visual field spatial resolution in more detail, the static visual target and the dynamic visual target It is also possible to set a program so as to measure the horizontal spatial resolution using two visual targets alternately.
In this case, the response criterion required for the subject is to press the space key when the movement of the visual target in the visual field or the two visual targets in the visual field can be recognized.
This is because it is considered that the movement is easily recognized in the peripheral visual field that is habituated in time, and the position is easily recognized in the central visual field that is difficult to be habituated in time.

4 When using a static visual target with a small size outside the central visual field and in the peripheral visual field, the user becomes accustomed to the visual perception of the visual target over time.
It is considered that the same phenomenon occurs in the visual field where the visual function level is lowered.
The program A of the present invention uses a dynamic visual target when measuring spatial resolution.
If the movement of a dynamic target with a certain speed is recognized, even if the target size is very small, the subject is not affected by visual habituation. At that time, it is possible to respond without hesitation.

5 The program A of the present invention uses a dynamic visual target in order to obtain a detailed visual field inspection result that cannot be obtained with a conventional perimeter in a relatively short time. In order to detect not only the visual field defect part and the blind spot but also the visual function lowered part due to a decrease in the density of pyramidal cells, etc., the spatial resolution is measured.
With the program A of the present invention, it is possible to obtain a visual field inspection result diagram that strongly suggests a retinal structure such as optic nerve axon running, vascularity, and the like.
This is because the measurement of the spatial resolution is performed without interruption in the horizontal direction by a dynamic target moving at a constant speed, so that the possibility of detecting discontinuity in visual sensitivity due to crossing of the retinal structure or the like increases.
By adjusting and setting the target characteristic and the vertical downward movement interval of the fixation target, it is possible to adjust the resolution of the visual field inspection result diagram, the level of visual function deterioration to be detected by the visual field inspection, and the like.

6. The program B of the present invention shows the visual function level obtained by the program A of the present invention as a vertical axis direction with respect to the two dimensions of the visual field in a three-dimensional manner on the display according to the height difference, and rotates the three-dimensional view from any direction. Make the structure observable.

7 In the program B of the present invention, when the three-dimensional structure is rotated with the arrow keys, if the structure is likely to go out of the display, the three-dimensional structure is brought to the center of the display by pressing a key such as adwx. It can be translated very easily.
When the three-dimensional structure is moved by the adwx key, releasing the arrow key allows the three-dimensional structure to be expanded in various directions, such as diagonally, so that an interesting three-dimensional display is possible.

1 In the program A of the present invention, before starting the visual field inspection, the fixation target can be adjusted and moved in the horizontal direction so that the visual field range to be inspected can enter the display as much as possible.
As a result, the range of the visual field in which visual field inspection can be performed by the program A of the present invention has been increased.

2 Spatial resolution information for the two-dimensional field of view is to move the target dynamically in the horizontal direction, move the fixation target vertically downward after sequentially measuring the spatial resolution of one line, but the dynamic target A method of starting the measurement of the next row while moving the dynamic target horizontally without changing the vertical position, or a method of moving horizontally while fixing the fixed target position. After measuring the spatial resolution for one line with the target, the dynamic target moves vertically downward, and the measurement for the next line starts from the left end in the horizontal direction. As soon as the measurement is completed, in the program A of the present invention, which is a method of sequentially moving the fixation target vertically downward, monotonicity and visual afterimages may be reduced by moving the fixation point, facilitating gaze and concentration. There is a possibility.
Since the program A of the present invention is a method of using a dynamic visual target along a fixed route that is not random, the program A is less monotonous than when a static visual target is presented at a random position.
The program A of the present invention measures the spatial separation in the horizontal direction of the display in the right direction without any spatial interruption, and measures the next line when the measurement for one line is completed. The subject responds by visual recognition following the change of the display display almost without any interruption in time, and the possibility of visual field inspection in which the subject's subjectivity does not enter much increases.

3 The response criterion required by the program A of the present invention for the subject is a very simple criterion that the subject presses the space key when the movement of the target is recognized in the field of view.
The program A of the present invention measures the horizontal spatial resolution using only the dynamic visual target. In order to measure the central visual field spatial resolution in more detail, the static visual target and the dynamic visual target 2 are used. It is also possible to set the program to measure the horizontal spatial resolution using the visual targets alternately.
In this case, the response criterion required for the subject is to press the space key when the movement of the visual target in the visual field or the two visual targets in the visual field can be recognized.
In this method, the two visual markers are different in the central visual field spatial resolution measurement, and the movement of the visual target is recognized in the peripheral visual field spatial resolution measurement.
The method of using two targets for measuring the spatial resolution of the visual field is that when the movement of the target is recognized in the visual field, the dynamic target moving in the horizontal direction by the space key pressed by the subject is When the static target is converted into a static target and the static target is displayed, a similar dynamic target starts moving from that position in the horizontal direction, and the subject recognizes the movement of the target in the field of view or By pressing the space key when the static dynamic two targets can be identified, the distance from the static target position to the dynamic target position at that time can be converted to the computer as a spatial resolution. The static target that was recorded and displayed disappears from the display, and at the position where the space key is pressed, the dynamic target becomes the static target, and the static target is displayed. A similar dynamic target starts moving in the horizontal direction. By repeating the processing described is a method of accumulating the spatial resolution information for viewing 2D.
The distance between the static visual target and the dynamic visual target thus measured is considered to reflect the spatial separation ability, cone cell density, visual cortex function, etc. of the position on the retina.
In the above method, the program A of the present invention is set so as not to display the static visual target.
From the viewpoint that the effective pyramidal cell density is fundamental, the possibility of recognizing the target movement and the possibility of distinguishing the two visual signs are considered to be approximately equivalent phenomena.
However, in the peripheral visual field, the influence of temporal habituation on vision may occur with respect to the possibility of distinguishing two visual markers.

4 When using a small static visual target outside the central visual field and peripheral visual field, habituation to the visual target occurs over time.
It is considered that the same phenomenon occurs in the visual field where the visual function level is lowered.
The program A of the present invention uses a dynamic visual target when measuring spatial resolution.
If the movement of a dynamic target with a certain speed is recognized, even if the target size is very small, the subject is not affected by visual habituation. It is possible to respond without hesitation.
The program A of the present invention measures the spatial separation in the horizontal direction of the display in the right direction without any spatial interruption, and measures the next line when the measurement for one line is completed. The subject responds to the change in the display display with almost no interruption in time, and the possibility of objective visual field inspection with little time for judgment on the target recognition by the subject increases.

5 Since the program A of the present invention uses a dynamic visual target, a detailed visual field inspection result diagram that cannot be obtained with a conventional perimeter can be obtained in a short time. By measuring the spatial resolution, not only a visual field defect part and a blind spot, but also a visual function lowered part due to a decrease in cone cell density or the like can be detected.
With the program A of the present invention, it is possible to obtain a visual field inspection result diagram that strongly suggests a retinal structure such as optic nerve axon running, vascularity, and the like.
This is because the measurement of spatial resolution is performed without interruption in the horizontal direction, increasing the possibility of detecting discontinuity in visual sensitivity due to crossing of the retinal structure or the like.
By adjusting and setting the target characteristic and the vertical downward movement interval of the fixation target, it is possible to adjust the resolution of the visual field inspection result diagram, the level of visual function deterioration to be detected by the visual field inspection, and the like.
By adjusting the size of the visual target, shortening the vertical movement distance of the fixed visual target, etc., it is possible to display the reduced cone function area along the optic nerve axon running on the display. It is effective for observation.
Since the present invention program A and the present invention program B have high-resolution examination result diagrams, the glaucomatous visual field characteristics, retinal neovascularization visual field characteristics, etc. in the initial stage are displayed in a clean and intuitive form on the display. Is possible.
The present invention program A and the present invention program B provide fairly precise information regarding the relationship between optic nerve axon travel and vascularity and dark spot shape.
According to the present invention program A and the present invention program B, information on the dark spot and the optic disc connection portion can also be obtained.
As the visual field phenomenon that can be detected and displayed intuitively on the display by the program A of the present invention, the following can be considered.
With the program B, these inspection results can be observed three-dimensionally.
Distribution of visual function level from the viewpoint of retinal function and spatial resolution in two dimensions, effective cone density, degree of decrease in effective cone density, blind spot size position, shape, dark spot size position, and Shape, functional level of optic nerve axon, degree of demyelination, early-stage glaucomatous visual field features that are difficult to detect with conventional perimeters with low resolution, normal-tension glaucoma visual field features with advanced myopia that are difficult to detect with conventional perimeters , Retinal neovascularization visual field features, visual cortex function level etc.

6. The program A of the present invention can clearly display the visual function level of the visual field and the size and shape of the blind spot on the display by the method of sequentially measuring the spatial separation ability of the visual field without spatial interruption.
The program B of the present invention shows the visual function level obtained by the program A of the present invention as a vertical axis direction with respect to the two-dimensional visual field in a three-dimensional manner on the display according to the height difference, and rotates the three-dimensional structure from any direction To be observable.
In the program B of the present invention, by pressing the arrow key, the spatial resolution structure of the three-dimensional field of view can be rotated, so that the spatial resolution structure can be viewed from various directions.
The three-dimensional structure can be confirmed from all directions, such as viewing the spatial separation structure from diagonally above, looking upside down, looking upside down, and looking from the back side.
In the case of the program B of the present invention, a portion having a large visual field space separation ability can be displayed in a convex or concave manner by the program.
It is also possible to display the two-dimensional region of the retina where the spatial separation capability of the visual field is large as a ground high-rise structure group, and the region where the spatial separation capability is low as an underground structure group.

7 However, when the three-dimensional structure is to be observed from various directions by rotation about the coordinate axis, the three-dimensional structure often deviates from the center of the display and goes out of the display.
A method for positioning the observation object at the center of the display is required.
In the program B of the present invention, when the three-dimensional structure is rotated using the arrow keys, if the structure is likely to go out of the display, the three-dimensional structure is displayed on the display by pressing a key such as adwx. It can be translated very easily to the center.
When the three-dimensional structure is moved by the adwx key, when the arrow key is released, the three-dimensional structure can be expanded in various directions such as oblique directions, so that an interesting three-dimensional display is possible on the display.

In the program A of the present invention, the visual field vision function as the detection target is set by changing the moving speed of the target, changing the size color and brightness of the target, shortening the vertical downward movement interval of the target, and the like. The level can be changed.
For example, when the size of the visual target is increased, the ability to detect peripheral visual field characteristics increases.
When the size of the target is reduced, the ability to detect the center visual field characteristic in detail is increased.
When the measurement program of the spatial resolution is completed, the program A of the present invention intuitively prompts the subject to prepare for recognition of the target that appears next from the left end by displaying the ← mark near the fixation target.
This is because a human cannot respond to the movement by pressing the space key or the like for several hundred milliseconds from the start of the movement of the dynamic visual target.
If the purpose is to detect dark spots, blind spots, etc., the inspection time is greatly shortened if the response preparation time is not set.
The program A of the present invention stores information for stereoscopically displaying the visual field and visual function level on the display in the form of rods.txt.
In the file, position information on the retina and spatial resolution information detected at the position are described.
In the program B of the present invention, there is a possibility that it becomes more intuitive if the transparency of the front surface is weakened with respect to the back side in stereoscopic display.

Invention program A and invention program B are written in the Hsp language.

Until now, there has not been a perimeter program that objectively detects not only the positions of dark spots and blind spots but also the level of visual function by moving the target in the horizontal direction. There is a limit to the ability of humans to identify the gray scale of the visual field inspection result as a three-dimensional structure.

The program A of the present invention can move the target horizontally at a constant speed, measure the spatial separation ability of the visual field in detail in a short time from the response frequency of the subject to the movement, and display the result neatly on the display. The program B of the present invention displays the spatial resolution obtained by the program A of the present invention in the vertical axis direction with respect to the two-dimensional visual field, thereby generating a three-dimensional structure representing the visual visual function level on the display, and rotating and translating it By making it possible, the structure can be observed from all directions.

When confining the examination range to perform a detailed visual field inspection, the subject's visual field is made visible to the subject as a display color defect, and the subject moves the inspection visual field to the center of the display while watching it. The display color deficient part that shows the shape of interest is set as the inspection range, and the subject's response is set so that the visual field is detailed enough to reflect the retinal structure by using a static target set to move at regular intervals. The inspection can be performed in a short time. At that time, a guide consisting of four line segments can be used around the static target in order to reduce the target recognition response error and shorten the inspection time. program

  The present invention relates to a visual field inspection program for limiting the inspection range from the viewpoint of inspection time in order to realize a visual field inspection that is detailed enough to reflect retinal structures such as optic nerve axon travel and vascularity.

  The present invention relates to a field-of-view inspection program that makes it possible to make the examination range limited purposeful and easy by using a method in which a subject's visual field state is recognized by a subject as a display color defect.

  The present invention relates to a optic nerve axon running, vascularity, using a static target set so that the subject moves at regular intervals according to the response of the subject after the subject has limited the examination range with reference to such display color defect display The present invention relates to a visual field inspection program that displays a visual field state of a subject in detail to the extent that suggests an isoretinal structure on a display.

In the response that the subject performs when he / she can visually recognize the static target, there is a change in the subject's visual recognition, and even when the response should be changed accordingly, the memory of the repeated response until then is In many cases, a rapid error is prevented and a response error related to the target recognition is generated.
This is a phenomenon in which the memory exceeds the recognition speed in the target recognition response.
The present invention uses a method of displaying a guide consisting of four line segments that are successively translated in the same manner around a sequentially moving static target. The present invention relates to a visual field inspection program which aims to greatly increase the accuracy of inspection while greatly shortening.

  It is also possible to set the static target movement interval to be large, and in such a case, the present invention relates to a visual field inspection program that enables a visual function state of the entire visual field to be displayed on a display in a very short time.

  The subject can recognize the visual field state most, but there is no program that can display the detailed visual field state on the display as the visual field inspection result accurately and at a high speed as the subject visually recognizes the visual field.

  There is no program that tries to limit the visual field inspection range for the purpose of realizing a visual field inspection that is so detailed that the optic nerve axon running, vascularity, etc. are suggested from the visual field inspection result diagram.

  There is no program that makes it possible to select a field-of-view examination range for the purpose.

In the visual field test result diagram, the dark spots and blind spot connection parts are considered to be important in detecting normal-tension glaucoma characteristics or initial stage glaucoma characteristics derived from advanced myopia. Since it is away from the fixation target, it is difficult for the subject to set the inspection range including those portions accurately and at high speed.
There is no program that makes it easy to set the dark spot and blind spot connection portion as the object of detailed visual field inspection in the inspection range.

In order to be able to select the visual field inspection range accurately and at a high speed, it is necessary for the subject to be able to refer to his / her visual field visual function deterioration state on the display when setting the range.
There is no program that allows the subject to recognize a visual field defect area including an imaginary dark spot or an area with reduced visual function as a display color defect in considerable detail, not limited to the fixation target.

There is no program that allows the subject to recognize in advance the display color defect before the visual field inspection of the running and shape of the visual field defect region that is considered to be derived from the retinal structure or the like.
There is no program that can set the inspection range so that the portion showing the shape of particular interest can be inspected in detail while looking at its visual field visual function deterioration state on the display.

  There is no program that attempts to increase the inspectable visual field range as much as possible when the visual field to be inspected is located at the edge or outside of the display.

  Confirmation of the target's target recognition by a method using a static target that is set so that the target recognizes the target's response sequentially, at regular intervals, horizontally, etc. There is no program that can display the state in detail and cleanly.

By performing the visual field inspection in great detail, the retinal structure such as optic nerve axon running, vascularity, etc. is recalled from the position shape of the visual field defect area such as the dark spot obtained as a result, and visual field defect is caused in the visual recognition of the subject There is no program that prompts you to guess what is the cause.
There is no program that does not only make the subject's visual field defect state communicable, but also conducts a visual field inspection in detail so that the cause of the visual field defect can be estimated.

In particular, when performing a visual field inspection in great detail, the subject often has to repeatedly perform the same response in a certain inspection range.
In such a case, when there is a change in the visual recognition of the subject with respect to the optotype and the optotype recognition response must be changed accordingly, the memory of the repetitive response so far prevents the subject from changing the response quickly.
The phenomenon that the memory response speed exceeds the cognitive response speed and increases the error becomes more apparent as the visual field inspection is performed at a higher speed. There is no program that attempts to avoid such a response error.
When a subject tries to generate a clear visual field inspection result diagram with no errors, and the subject tries to perform a visual field inspection with no error in the target recognition response, the response sequence is always considered in the reverse direction. The inspection speed is greatly reduced.

  There is no program that greatly increases the accuracy of the inspection result while greatly reducing the visual field inspection time by the method of displaying the guide consisting of four line segments around the static visual target.

  There is no program that attempts to increase the movement interval of a static visual target that moves in a certain direction such as the horizontal direction in order to perform a visual function test of the entire visual field in a very short time.

The visual field of the subject cannot be recognized unless it is a subject.
However, the visual field recognition of such a subject cannot be transmitted.

The visual field of the subject cannot be recognized unless it is a subject.
However, in the case of an imaginary dark spot, the position and shape of the dark spot cannot be accurately recognized even by the subject unless the position is very close to the fixed viewpoint.
In addition to being in a state where the subject's visual field state is not in a communicable state, the subject himself / herself may not be able to accurately recognize the subject's visual field state.

  When staring at a fixation target, the visual field of interest as a visual field inspection target may not fit in the display.

In a rough inspection such as a conventional perimeter, the position shape of the visual field defect area such as a dark spot obtained as a result of the inspection is not detailed enough to suggest the retinal structure, etc., and details about the cause of the visual field defect etc. It is impossible to guess.
It is impossible to estimate in detail the relationship between the visual field defect region of the subject, the optic nerve axon running, and vascularity of the subject from the examination result by the conventional perimeter.

However, a detailed visual field examination that reflects the retinal structure takes a very long time to perform.
Therefore, if a very detailed visual field inspection is to be performed, it is practical from the viewpoint of inspection time to limit the inspection range.
However, if the subject cannot recognize the position and shape of his / her visual field defect region, it is impossible to select the visual field inspection range for the purpose.

  For example, even when trying to select a dark spot or blind spot connection part that is considered important for detection of normal-tension glaucoma characteristics derived from advanced myopia or initial stage glaucoma characteristics, such parts Is somewhat distant from the fixation target, it is not easy for the subject to set the range accurately.

  For example, optic nerve axon travel, visual field defect area along vascularity, which is considered to be important for detection of normal pressure glaucoma characteristics derived from advanced myopia, or early stage glaucoma characteristics Even if you try to set the field of view as a field of view, such a part is far from the fixation target, or the visual function of such a part may be at a low level. Setting it is not easy.

When a very detailed visual field inspection is performed using a static target that sequentially moves in response, a subject often has to repeatedly perform a similar response within a certain inspection range.
This is because when a very detailed visual field inspection is performed, the visual recognition of the subject with respect to the static visual target is constant within a certain range.
In such a case, the subject has a change in the visual recognition of the static target, and when the target recognition response is to be changed accordingly, the same repeated response is stored in memory. A phenomenon occurs in which memory affects response rather than recognition.
As the subject increases the response speed and shortens the visual field inspection time, the memory response exceeds the cognitive response, resulting in an increase in response error.
When the response speed is increased by the subject, the visual recognition is memorized by the response error several times and becomes available for the response, so the memorized response becomes equivalent to the recognizable response and the number of errors is limited.
However, the recognition that the response to the target recognition is error and the recognition by the subject that the recognition and the memory response have deviated in the visual field defect partial contour affect the driving force of the subject with respect to the visual field inspection.
The inspection result diagram also has a slight error in the outline of the visual field defect region.

  However, if the test result diagram is to be made clear, the test subject's test speed is greatly reduced because the range in which the test subject must predict the visual field defect region in response to the target recognition increases.

  When the movement interval of the static visual target is set short, the inspection of the entire visual field takes a very long time.

In order to guess what is causing the visual field defect area, etc., it is necessary to consider the position and shape of the visual field defect area from the relationship with the retinal structure, etc. There is a need to do.
If a very detailed visual field inspection is performed, it is practical from the viewpoint of inspection time to limit the inspection range.
However, if the subject cannot recognize the position and shape of his visual field defect region when setting the examination range, it is impossible to limit the visual field examination range appropriately.

In order to accurately select the visual field range to be subjected to visual field inspection, it is necessary that the subject can refer to his / her visual field visual function state on the display in some detail before setting the range.
The program of the present invention is a method that allows a subject to set a visual field inspection range while viewing his or her visual field defect state on a display.

  The program of the present invention selects the part of the display color defect area that is of particular interest as the visual field inspection range by the method of alternately displaying the display background color in red-orange and black at a preset short-time interval. Enable.

The program of the present invention enables the subject to grasp the visual function deterioration region of the subject as a display color defect including the visual field loss region far from the fixation target.
By the program of the present invention, the subject can see the visual function-decreasing region of his visual field as a color defect on the display. As a normal-tension glaucoma characteristic derived from advanced myopia, or as an early stage glaucoma characteristic, the area where the visual function along the optic nerve axon running, vascularity etc. is considered to be important, The program of the present invention makes it possible to observe as a display color defect.

In order to increase the inspectable visual field range, the program of the present invention can move the fixation target before setting the visual field inspection range.
The program of the present invention allows the subject to move the fixation target so that the portion of particular interest is as centered as possible while looking at the position and shape of the visual function lowering area in his visual field on the display.
The visual field to be inspected can be moved to the center of the display as much as possible.

  The program of the present invention uses a static visual target that is set so as to move sequentially at regular intervals according to the visual target recognition response of the subject in order to record and display the visual field loss and the visual function deterioration state of the subject on the display.

First, the subject blocks the visual field on one side and stares at the fixation target with the other visual field.
The program according to the present invention is set in advance in the horizontal direction or the like each time the static target displayed on the display is replied that the subject can recognize or cannot recognize the static target. This is a method in which the inspection of the next line is started in the same manner when the inspection of one line is finished after moving by a certain interval.

  For the purpose of increasing the speed of visual field inspection and reducing the target recognition response error by the subject, the program of the present invention displays a guide that moves in parallel in the same way around the static target that responds by the subject. You can also

The guide consists of four line segments in the vertical and horizontal directions around the static visual target.
The four relatively short guide line segments are separated from the static visual target at the center by a certain distance in order to be separated from the static visual target in the visual recognition.
In order to separate the static target and the four guide segments for visual recognition, when the static target is displayed in green, for example, the four guide segments are displayed in reddish orange.
The red-orange display of the guide that sequentially moves in response to the test subject's target recognition may be sensitive to the visual function degradation area.

The guide line segment increases the speed and accuracy of visual field inspection.
The guide line segment allows the subject to recognize the visual field state around the sequentially moving static target.

For example, when the vicinity of a dark spot region in the central visual field is inspected by a sequentially moving static target having four guide segments, a sequentially moving static target having a green display is seen, but four guides are visible. The subject can recognize in advance a state in which any of the line segments is partially reddish orange.
Therefore, the subject can recognize that there is a visual field defect region in the vicinity while recognizing the sequentially moving static visual target displayed in green.

  The program of the present invention allows the subject to predict the visual field state around the static visual target, and allows the subject to change the visual target recognition response speed accordingly.

The subject can recognize in advance the outline portion of the visual field defect region by the four guide line segments. Only by the contour portion, the test subject slightly reduces the response speed to the target recognition, and the response error by the test subject is greatly reduced. This is because most of the response error by the test subject occurs only in the visual field defect outline.
Four guide segments greatly increase the accuracy and ease of visual field defect contour extraction.
Alternatively, since the position of the visual field defect region can be predicted in advance by four guide segments, the response error can be reduced without a decrease in response speed.

In the case of the method using the four guide line segments of the program of the present invention, the subject's response to the visual change of the target recognition is not easily influenced by the memory of the repeated response so far.
This is a phenomenon in which the recognition of the guide line segment defect exceeds the memory of the repeated response.
This is because the recognition of the guide line segment defect is memorized to some extent.

  When the program of the present invention and four guide segments are used, the subject can display his / her visual field state on the display in a very high speed and in a very detailed and accurate manner.

When the present invention program uses four guide segments, it can be examined whether or not the subject can clearly recognize the static visual target with respect to the four guide segments.
In the central visual field, the static visual target for the four guide segments can be clearly recognized.
However, when moving sequentially to the peripheral visual field, it is also possible to detect a range in which the recognition of the static visual target for the four guide segments becomes unclear.

In order to grasp the visual function of the entire visual field in a very short time, the sequential movement interval of the static visual target is increased.
Even if the interval of the static target is large, if the size of the static target is very small, a visual field inspection that can detect even a slight deterioration in visual function is performed in a very short time. It is possible.

The subject's precise and detailed visual visual function is incapable of being transmitted.
However, the subject's visual field state is most recognizable by the subject.
The subject can recognize an approximate position shape as long as it is a dark spot in the central visual field that is close to the fixation target.
However, in the case of an imaginary dark spot, the position shape of the dark spot cannot be accurately recognized even by the subject unless the position is very close to the fixed viewpoint.
The program according to the present invention performs two-color alternate display such as red-orange, black, etc. with an appropriate short time interval for the display background color.
By the program of the present invention, the test subject can see the area where the functional deterioration is visually occurring in his / her visual field as a color defect of the display.
In the visual function deterioration region, it is considered that this phenomenon is caused by delay in visual follow-up to the color change of the display.
By the program of the present invention, the subject can view the visual field defect region including the imaginary dark spot and the region where the visual function is deteriorated as the display color defect in detail.
By the program of the present invention, the subject can see the running and the shape of the visual field defect area considered to be derived from the retinal structure on the display in advance before the visual field inspection.
The program of the present invention suggests that the shape of the display color defect region that the subject can see on the display is very continuous, and the visual field defect region is due to the retinal structure or the like.
Compared to the conventional perimeter inspection results, it is possible to observe a very continuous display color defect shape.

The subject can recognize not only the central visual field but also the peripheral visual field by using the program of the present invention. The subject can see the visual function-decreasing region of his visual field as a color defect on the display.
As the normal-tension glaucoma characteristic derived from advanced myopia, or the glaucoma characteristic in the initial stage, the area where the visual function is slightly decreased along the optic nerve axon running, vascularity, etc. The program of the present invention makes it possible to observe as a display color defect.

When the visual field to be inspected is toward the edge of the display, the program of the present invention attempts to increase the visual field inspection possible range by moving the fixation target.
In the program of the present invention, the subject can move the fixation target so that it is as close to the central visual field as possible while looking at the position of the visual function degradation region on the display.

  When two-color display of the display color is not performed alternately, the dark spot and blind spot connection part is far from the fixation target, so the subject cannot recognize the state of the position in detail and set the examination range accurately. Is difficult.

  In the program of the present invention, it is very easy to select a dark spot / blind spot connection area as an inspection range by two-color display alternately.

  It is very easy to set a portion showing a shape of interest from the display color defect portion as the visual field inspection range.

  If the visual field inspection range is narrowed, even a very detailed visual inspection can be performed in a very short time.

A very detailed visual field inspection result diagram reflects the retinal structure and the like.
By displaying visual field test results that are as detailed as visual cell units or ganglion units, such as cones, on the display, the relationship between the subject's visual field deficit, the optic nerve axon travel, and vascularity of the subject can be estimated in detail. .
The program of the present invention not only makes the visual field defect state of the subject communicable but also makes it possible to infer the cause of the visual field defect.

  The test result diagram displayed on the display by the program of the present invention can be stored in a computer and can be compared in time series.

When using the program of the present invention and four guide line segments, the response error is greatly reduced, and the accuracy of visual field defect contour extraction is greatly increased.
This is a phenomenon in which the recognition of the guide line segment defect exceeds the memory of the repeated response.
This is because the recognition of the guide line segment defect is memorized to some extent.

When the present program uses four guide segments, the subject can recognize that the static visual target has approached the dark spot portion.
If the static target is far from the dark spot, it responds to the high speed using the response memory up to that point, and when the static target approaches the dark point, the subject can recognize four guide line segment defects in advance. , It is possible to bypass the memory of repeated responses until then, slightly lower speed, slightly longer target recognition judgment time, responding in detail, etc. The subject can select the response speed, almost completely error It is possible to determine the outline of a dark spot without a visual field or a visual field defect region.
A very accurate visual field defect region contour result can be obtained without adjusting the position of the visual field defect region contour position by the subject.
Alternatively, the four guide segments allow the subject to predict the dark spot position around the static visual target, which may reduce the error without reducing the response speed. However, the accuracy of the inspection result increases.

  When the present invention program and four guide line segments are used, the visual field state of the subject can be displayed on the display at a very high speed. With the four guide segments, the subject can confirm that his visual field characteristics can be detected very accurately at the time of visual field inspection.

  The four guide line segments are effective particularly when the position shape of the visual field defect region is to be detected in detail in the central visual field.

However, it is also possible to detect whether or not the static visual target can be clearly recognized in the central portion of the four guide line segments around it.
It is thought to be related to the spatial resolution.
In the vicinity of the central visual field and the fixation target, the static visual target can be clearly recognized in the central portion of the four guide line segments.
However, when the static target moves sequentially to the peripheral visual field, there is a range in which the static target for the four guide segments becomes unclear.
The range can be extracted.
Alternatively, it is possible to perform visual field inspection to extract visual functions at other levels by adjusting the four guide line segments to be thicker or the size of the central target to be increased.

When the sequential movement interval of the static visual target is increased, even the entire visual field inspection can be realized in a very short time.
The entire field of view can be grasped.

  Even if the interval between the movements of the static target is large, if the size of the static target is made very small, it is possible to detect areas where the visual function has deteriorated to a considerably low level while performing high-speed inspection. It is.

  By slightly increasing the sequential movement interval of the static visual target, the visual field inspection time is considerably shortened.

If the display background color two-color alternating display time interval is changed, the detectable visual function deterioration level can be changed.
This is considered to be because the speed of visual color tracking with respect to a change in the display background color changes depending on the degree of visual function deterioration due to a decrease in cone cell density or the like.
It is possible to set the display background color display time by how many milliseconds it is red-orange and how many milliseconds it is black.
The combination of two display background colors can be changed to another combination by a program.

  By changing the size of the visual target and the color luminance, it is possible to extract a visual function-decreasing region at another level from the subject visual field and display it on the display.

For example, when the target is made very small, a visual field defect region that is located in the central visual field can be detected in great detail.
The possibility of detecting an area where the visual function is slightly reduced is also increased.
In the case of enlarging the visual target, it is possible to detect positions and shapes such as dark spots and blind spots for the entire visual field, and to detect a significant change in visual function in the peripheral visual field beyond the blind spot.

When the present invention program uses four guide segments, the size of the static visual target and the thickness of the four guide segments around it can be adjusted by the program.
As the guide, in addition to the four guide segments, a circle display centering on a static target may be considered.

If the target movement interval is increased, even the inspection of the entire visual field can be realized in a very short time.
The entire field of view can be grasped.
Even if the optotype movement interval is large, if the size of the static optotype is made very small, it is possible to detect a considerably low level visual function degradation region while performing high-speed inspection.
If the target movement interval is slightly increased, the inspection time is considerably shortened.
The test result diagram displayed on the display by the program of the present invention can be stored in a computer and can be compared in time series.

Target size for ;; guide This program is written in Hsp language.

If it is attempted to perform a detailed visual field inspection reflecting the retinal structure, it takes a very long time, so it is appropriate to limit the inspection range. However, since the subject cannot accurately recognize the position and shape of his / her visual field defect region, he / she cannot select the examination range for the purpose.

In order to carry out a detailed visual field inspection, when the inspection range is limited, the visual field of the subject should be made recognizable to the subject as a display color defect, and the subject can move the inspection visual field to the center of the display while watching it. The display color deficient part showing the shape of interest is set as the examination range, and the response of the test subject is used to make a static target set to move at regular intervals, so that the details of the retinal structure are reflected. Visual field inspection can be performed in a short time. At that time, a guide consisting of four line segments can be used around the static visual target in order to reduce the target recognition response error and shorten the inspection time. This invention program which can be done.

Program-controlled static optotype that enables a general computer to detect a visual field area with slightly reduced visual function, which is considered to be characteristic of normal-tension glaucoma or the first stage of glaucoma derived from high myopia, And a perimeter program that makes it possible to display in detail the shape of the visually impaired area on the display.

  Normal eye pressure glaucoma from advanced myopia, or a program-controlled static visual target that is detected by a general computer to detect a visual field area that is slightly degraded in visual function, which is considered to be the first stage characteristic of glaucoma, and The present invention relates to a perimeter program that displays in detail the shape of the visual function-decreasing region on a display.

Since the conventional perimeter has low resolution, normal visual pressure glaucoma derived from high myopia or glaucoma is considered to be the first stage feature of visual acuity, and the visual function slightly decreases along the optic nerve axon running etc. Failure to detect the region in detail.
The conventional perimeter cannot detect in detail the position shape of the visual field area where the visual function is slightly degraded, so that the visual field characteristics peculiar to advanced myopic normal tension glaucoma can be compared with the retinal structure such as optic nerve axon running , It may not be detected.
Since the conventional perimeter cannot detect in detail the position shape of the visual field region in which the visual function is slightly deteriorated, there is a possibility that detection of glaucoma visual field characteristics in the initial stage has failed.

  Conventional perimeters have a low resolution examination, and the target used for the examination does not have the ability to sensitively detect areas with slightly reduced visual function. It is impossible to detect in detail the position and shape of the visual field area where the visual function is slightly deteriorated, which is considered to be a characteristic feature of pressure glaucoma or glaucoma.

  A conventional perimeter cannot detect glaucoma characteristics at a very early stage.

When a visual function degradation region is generated in the visual field, blinking at high speed and high frequency while looking at paper or the like makes it possible to recognize the position and shape, but such subject recognition can be transmitted. Not in state.
In the conventional perimeter, it is impossible to detect a region where the visual function is slightly deteriorated, which can be recognized when the subject blinks at high speed and high frequency.

The static visual target and perimeter program of the present invention attempts to make a general computer a perimeter that is highly sensitive to such an extent that it can detect even a region where the visual function is slightly deteriorated.
However, in a general computer, since the display drawing processing speed is slow, it is difficult to display a static visual target that can detect a visual function deterioration region with high sensitivity.

  The present invention provides a static visual target used in a visual field inspection program with a detection capability for a slight decrease in visual function. For example, when blinking is performed at high speed and high frequency while looking at paper or the like, the visual function In other words, the field of view that causes a decrease in the brightness is used as a dark, low luminosity region.

  In the visual field area where the visual function is slightly reduced due to a decrease in effective cone cell density, etc., the visual follow-up to changes in color and brightness may be delayed, the color and brightness displayed immediately before However, there is a possibility that the visual recognition may affect the short-time property.

  When a subject who has an area with a slightly reduced visual function in his visual field blinks at a high speed and high frequency, he can recognize such an area clearly and darkly with respect to other parts of the visual field. When applied, for example, if a static target with red-orange display can be blinked on a display with a black background color at high speed and high frequency blinks, the red-orange color is equivalent to the visual function degradation visual field area. There is a possibility that a phenomenon that can be perceived darkly and visually occurs.

  The red-orange static visual target flashes at high speed and with high frequency blinks within the visual field area where visual function is reduced by adjusting the luminosity or luminosity density of the red-orange static visual target. There is a possibility that a phenomenon in which visual recognition is not performed due to a decrease in visual luminosity or visual recognition becomes difficult may occur.

  However, if the static target is blinking on the display at time intervals of about blinks, the subject must wait for several blinks before confirming and responding to the possibility of target recognition. It will increase very much.

  From such a point of view, the present invention provides a very small red-orange target at the tip position of the radius, which is very short but not displayed, centering on the position where the target should be presented under the black display background color. One is placed, one red-orange target is placed at the position where the radius is twice that length, and the two red-orange targets are quantized around the position where the target should be presented. A static target for detecting a visual function deterioration region that can be used even by a general computer by a method of circular trajectory at high speed.

Quantum high speed means that the circular velocity that can be realized for a red-orange target is too slow at the display drawing processing speed of a general computer, so the angular velocity is set to 26.6 ° when determining the circular orbit coordinates of a red-orange target. This is a method of increasing the central angle considerably discontinuous.
In the case of the static target of the present invention, for example, set to degreez = .degreez + 26.6.

The diameter of the circular orbit corresponds to the size of the static visual target.
When the presentation density of the red-orange target at any position on the circular orbit approximates high-speed and high-frequency blinks, recognition of the static target of the present invention causes a slight decrease in visual function. In some areas, it is considered that a more difficult phenomenon occurs than in other fields of view.

By using the static visual target and perimeter program of the present invention, it is possible to detect a region in which the visual function is slightly deteriorated in the subject visual field, and to display the position shape in detail on the display. become.
Using the perimeter program of the present invention that sequentially moves the static target of the present invention in the horizontal direction at regular intervals every time the target recognizes the target recognition response, it detects not only the blind spot blind spot but also the ordinary target. An area where the visual function that cannot be performed is slightly deteriorated can be intuitively displayed in detail on the display.

  In fact, the phenomenon that the static visual target of the present invention is not recognized in the visual function reduced region of the subject visual field, or the movement visually recognized from the static visual target of the present invention, The phenomenon of not being recognized but being recognized statically occurred.

The static visual target of the present invention can detect glaucoma characteristics at a considerably initial stage.
The perimeter program of the present invention makes it possible to display the glaucomatous visual field characteristics at a very initial stage on the display in such a detail as to remind the running of the optic nerve axon.

  The static target of the present invention and the perimeter program of the present invention may be able to clearly show the detailed position and shape of the visual field area that will become a dark spot for the subject in the future on the display.

  The static visual target of the present invention easily recognizes the dynamic characteristics generated in the visual sense, and is always recognized as moving from the right after being presented. Even if there is, it is possible to respond by pressing a button as soon as the visual recognition is confirmed. As a result, the visual field inspection can be performed at a very high speed.

When presenting the static visual target according to the present invention, the response criterion required for the subject is, for example, when the subject can recognize a movement like a diphragm on the static visual target in the visual field, and presses the right arrow key.
When the subject recognizes that the static visual target of the visual field does not move like a double eye and is static, or when the static visual target cannot be recognized in the visual field, the left arrow key is pressed.

  It is easy for the subject to recognize whether or not the static visual target of the present invention presented on the display is moving like a double eye in visual recognition.

  In order to further simplify the response judgment required by the subject regarding static target recognition, the static target of the present invention cannot be recognized visually in an area where the visual function is slightly degraded. Adjust and set the luminosity density and color of the target.

Conventional perimeters with low resolution fail to detect normal-tension glaucoma and initial stage glaucoma characteristics consisting of a slight decrease in visual function and to guess the cause.

The program of the present invention that makes a general computer a high-sensitivity perimeter capable of detecting initial stage glaucoma characteristics.

Applying a phenomenon that can recognize areas such as comparative dark spots with darker continuous contours in the visual field at high speed and frequent blinks, a red-orange static visual target is displayed on a black background. If the color can blink, it is expected that the red-orange color will be recognized quite darkly in the field of view where the visual function is degraded.
The present invention is a static target for detecting a visual function deterioration region by rotating two red-orange targets under a black display background color and circular orbit rotation at a high quantum speed from the viewpoint of drawing processing possibility. is there. While the target is displayed with a time interval of about blinks, the static target can always be displayed stochastically during the test, and the test target is always able to recognize and respond to the target, reducing the test time. To do.

In step S21 of the target display control process shown in FIG. 58, the central processing unit sets the size of the measurement screen.
In the embodiment of the present invention, the measurement screen 262 is specified as, for example, an ID0 window having an x coordinate direction width of 600 dots and a y axis direction height of 460 dots.

  In step S22, the central processing unit sets the background color of the measurement screen. In the embodiment of the present invention, for example, the luminances of R, G, and B are designated as black that is 0, 0, and 0, respectively.

In step S23, the central processing unit sets the target color of the target to be statically displayed on the measurement screen, and then sets the display position of the static target on the measurement screen.
In the embodiment of the present invention, the target colors of the statically displayed targets are designated as colors whose luminances of R, G, and B are 100, 220, and 60, respectively. In the embodiment of the present invention, the central processing unit displays the static target as, for example, a dot. In the embodiment of the present invention, for example, the display position is designated as a value (one dot unit) where the x coordinate is firstz and the y coordinate is 200 + 30.

  In step S24, the central processing unit initializes the value of xcoordinatez (in units of one dot) to 0, and then initializes the input receiving unit.

In step S25, the central processing unit presents a measurement screen background color in a predetermined part of the measurement screen other than the target statically displayed in step S23, that is, a path along which the target moves. Fill with two rectangles.

In the embodiment of the present invention, the target color of the target that is dynamically displayed is specified as, for example, colors with R, G, and B luminances of 100, 220, and 60, respectively. The central processing unit displays the dynamic visual target by moving, for example, a dot dot. In the embodiment of the present invention, the display position of the dynamic visual target is designated as a value having an x coordinate of firstz + xcoordinatez and a y coordinate of 200 + 30, for example.

  In step S27, the central processing unit executes secondz ← firstz + xcoordinatez, that is, the central processing unit stores the value of firstz + xcoordinatez in secondz which is a variable.

In step S <b> 28, the central processing unit sets dynamic characteristics of the target that is dynamically displayed on the measurement screen by arithmetic processing.
In the embodiment of the present invention, for example, the dynamic characteristic is designated by causing the arithmetic unit 103 to calculate xcoordinatez ← xcoordinatez + 1.

In step S29, the central processing unit determines whether or not an input relating to the movement recognition of the target has been received by the input receiving unit.
If the central processing unit determines that the input regarding the target movement recognition has not been received by the input receiving unit, the central processing unit returns to step S25 and continues the processing. When the central processing unit determines that the input regarding the movement recognition of the target has been received by the input receiving unit, the central processing unit proceeds to step S30.

In step S30, the central processing unit executes firstz ← secondz, that is, the central processing unit stores the value of secondz in firstz.
Then, it returns to step S23 and continues processing.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
A system configuration for realizing the above functions will be described with reference to the drawings.
1 shows an appearance of an information processing apparatus equipped with a character processing apparatus, for example, a personal computer.
In the figure,
It is a display for displaying an input character string and a character string.
The output can also be printed by a printer which is an output device.
Enter the character string to be processed,
The keyboard has a cursor key (also called an arrow key) for moving a character cursor displayed on the display and designating a character position.
It is a pointing device for specifying the position of the display screen.
For example, a mouse.
The figure shows a typical internal configuration of the information processing apparatus. In the figure, C P U is H D
It functions as a processing device by executing a processing program stored in D (hard disk). Note that C P U controls the entire apparatus according to the operating system.
The system memory is used for storing data used in the CPU processing, data displayed on the display, and data related to character processing. Furthermore, data necessary for system control is also stored in the system memory.
In addition to the operating system and processing program described above, a program is stored in H D D.
Note that the above-described data stored in the HD can be implemented from the CD ROM through a CD ROM drive (not shown). A floppy disk drive is used when the data is mounted from a floppy disk.
An input / output interface (I / O) for connecting a circuit and a bus described later. I / O transfers a signal output from C P U, and I / O transfers input information from the keyboard to C P U. I / O transfers image data to be displayed on the display.
Prior to the description of the operation of the processing system having the above circuit, the flow of processing data of this embodiment will be described with reference to the drawings.
The character string input from the keyboard can be the target of the processing program.
The processing program accepts a user's character cursor operation, mouse operation, and other key operations such as insertion and deletion, and performs processing according to the processing method described above according to the operation.
Data stored in the storage device (input signal) when a function is instructed.
The processing content of C P U will be described with reference to the flowchart of the figure.
The processing procedure is stored in advance in the HD as a processing program in the form of a C PU executable program language. When CPU is executed, it is loaded from the HDD into the system memory.
The figure shows the main processing procedure of the processing program. The processing procedure in the figure is executed when there is an input event, that is, a key input from the keyboard or an information input from the mouse.
The input may be confirmed by sound from a speaker.
The figure shows a processing procedure for realizing the function. When the result is stored in the system memory and displayed on the display, the illustrated processing procedure is executed. C P U is stored in a dedicated processing area (hereinafter abbreviated as a work area) in the system memory, and counts the number of characters.
The number of characters counted (including character strings that are not stored in the work area as character strings) exceeds the predetermined number of characters.
Next, the total number of characters in the character string is calculated (step S), and again compared with a predetermined number of characters (step S). Thereafter, the loop process of steps S to S is repeated.
The above processing is executed by C P U.
Similar processing can be performed when a character string is continuously input from the keyboard.
The figure shows the processing contents when a character in the fixed character string is designated by the character cursor. In this processing procedure, when the C P U detects that the character cursor is moved by the cursor key of the keyboard or the mouse, the C P U determines that there is a processing related instruction, and the processing procedure of the figure is changed to step S → Proceed to S and execute the processing procedure shown in the figure. In the figure, when C P U detects that the position of the cursor key is located in the character string, the candidate corresponding to the character string including the designated character position is read from the system memory and displayed in the form as shown in the figure. (Steps S → S → S → S).
In this embodiment, in association with the display by specifying the position of the character cursor key,
The following functions are provided. When the user operates a specific key on the keyboard (for example, the E N T E R key) while the character string is specified by the character cursor, the operation is detected in step S and the character cursor moves to the character string. To do.
Next, keyboard input control will be described with reference to the drawings.
The processing procedure in the figure is executed by a constant cycle interrupt. C P U reads the key code signal held in the I / O for the keyboard and determines whether or not there is a key input.
If there is a key input, the key code signal is not held, so that the determination result of step S advances to step S.
In this step, C P U resets the count value to zero,
Slightly longer than one key press time. When there is a continuous key input, the procedure from step S → S is repeatedly executed.
In addition to the above embodiment, the following embodiment can be implemented.
Explanatory drawing which shows transition of operation, and a block diagram which shows the external appearance of the information processing apparatus which has.
The block diagram which shows an internal structure, The block diagram which shows the flow of the data of the Example of this invention.
The flowchart which shows the main processing procedure of this embodiment, the flowchart which shows the processing content for storage of an input character, and a display.

curvature separation.
Conventional campimeters are affected by the spherical shape of the retina.
The visual field test results are affected by the curvature of the eyes.
The present invention program, the two-point recognition minimum distance dz colord, not only moves the dynamic target even if it is a campimeter, but also positively moves the fixed target not only in the vertical direction but also in the horizontal direction. By moving it, the influence of the curvature of the eye on the visual field inspection result diagram is reduced. Try to extract more spatial resolution

The observation speed increase of the off-center visual field is curvature.
The observation speed does not increase much in the off-center visual field. Conventionally it is curvature + resolution. curvature effect >> space separation effect. For calculation.

A fixation target display for displaying a fixation target for gaze and a means for accepting motion recognition establishment of the dynamic target after the target that has been a static target for a moment becomes a dynamic target Control means;
Means for setting a plurality of horizontal scanning lines along which the fixation target moves along the observation screen at a predetermined line density;
When the motion target calculates the position of the fixation target at the right end of the display or more to the right when a response for motion recognition of the dynamic target is accepted, scanning for the horizontal scanning line near the fixation target is completed. A mark indicating that this is displayed for a predetermined moment, and after the mark is removed from the screen, the fixation target scans along the horizontal scanning line for the next fixation target (by changing the scanning line). Means for starting
The fixation target display control means moves the fixation target along the fixation target scanning line by the distance moved by the dynamic target detected at that time each time an input response related to dynamic target movement recognition is received. Means for moving the detected distance in a storage device together with the coordinate position of the observation screen at the time of detection;
The arithmetic unit converts the stored distance into color shading, and refers to the stored coordinate position information to create a scan diagram by painting the recording screen in a rectangular shape. means,

In response to the operation signal from the switch, the control unit displays the fixation target at different positions on the LCD display surface. Note that the display position of the fixation target corresponding to the above fixation position can be set in advance based on, for example, data, or can be set in advance for each eye to be examined (field-of-view image). .

The control unit controls each part of the apparatus to cause the observation apparatus to execute an operation corresponding to each mode.
The figure shows an aspect of a tomographic image (group) formed by the image forming unit. In the arithmetic processing, for each scanning line R i, a visual field image G i along the scanning line R i is formed based on the images in the depth direction at the n scanning points R i 1 to R in thereon. . At this time, the image forming unit refers to the position information (scanning point coordinate information) of each of the scanning points R i 1 to R in to determine the arrangement and interval of the scanning points R i 1 to R in, It comes to form.
Next, a process for forming a three-dimensional image of the visual field by the image processing unit will be described.

Further, the image processing unit can form an image of a field of view from any direction other than the main scanning direction or the z-axis direction based on the three-dimensional image. When the direction is designated, the image processing unit specifies the position of each scanning point (and / or interpolated) from the designated direction, and forms a stereoscopic image of the visual field visual function from the direction.

This control information includes
For example, scan control information related to target scan, projection position control information related to the projection position of the fixation target on the fundus, target brightness control information related to target brightness reduction, and so on. explain.
(Scan control information)
  First,
The scanning control information will be described.
This scanning control information is stored in the scanning unit when the field image Ga is formed.
(Display) Information indicating the scanning mode of the projection position of the target on the fundus by a galvano mirror (which may be a drive mechanism).
here,
“Scanning mode” includes at least
It includes aspects related to the arrangement, interval, trajectory, and the like of the projection positions of the target on the fundus.
An example will be described in which the target is scanned as shown in the figure. Scan shown in the figure
In the example, the visual target is first projected at the scanning start position R S (scanning point R 1 1).
Next, the projection position is moved to the scanning point R 1 2 separated by a predetermined distance (in the display) by a predetermined distance (= constant = Δ x) in the x direction, and the target is projected. Similarly,
The target is displayed at each scanning point R 1 j while sequentially moving the display position of the target on the display by Δ x in the x direction, and the scanning along the scanning line R 1 is completed.
When the target is projected onto the last scanning point R 1 n on the scanning line R 1, the projection position is moved to the first scanning point R 2 1 on the second scanning line R 2 to project the target. .
Here, adjacent scanning lines R i, R (i + 1) (in the y direction)
The spacing (on the display) is denoted as Δy.
Subsequently, each scanning point R 2 j on the scanning line R 2 is scanned in the same manner as the scanning on the first scanning line R 1.
Similarly,
The target is projected onto the fundus while sequentially moving the display position on the display for projection onto the fundus to the last scan point R m n on the last (m-th) scan line R m.
The scanning control information at this time includes
For example
The following five pieces of information are included.
Information (scanning start position information) representing the target display position coordinates (which may be the position of the galvanometer mirror) on the display when the target is irradiated to the scanning start position R S (scanning point R 1 1);
The displacement Δ θ x of the position (direction of the reflecting surface) of the galvanomirror corresponds to the interval Δ x between the scanning points R i j and R i (j + 1) adjacent to the scanning line R i direction (x direction). Information) (x-direction scanning interval information);
Corresponding to the interval Δ y between the adjacent scanning lines R i, R (i + 1) (may be a displacement Δ θ y of the position of the galvano mirror (direction of the reflecting surface))
(Y-direction scan interval information);
The number of scanning lines R 1 to R m (m) is shown.
Scan line number information;
Scan point number information indicating the number of scan points R i 1 to R in on each scan line Ri
And are included.
Here, the scanning control information can be configured to include only information (arrangement information) indicating the arrangement form of the scanning points, or the interval between adjacent scanning points (the interval in the x direction and / or the y direction). (Interval) can also be included.
Furthermore,
The scanning control information can include information (scanning trajectory information) indicating the trajectory of the display position on the display of the target projected onto the fundus.
This scanning trajectory information is information representing the projection order of the visual target when the visual target is sequentially projected onto a plurality of scanning points.
For example
In scanning of scanning points R 1 1 to R mn arranged in m rows and n columns shown in the figure, first, scanning points R 1 1 to R 1 n of the first row (scanning line R 1) are performed. sequentially scans the projection position in the x direction, then scans the projection position to the first scan point R 2 1 of the second row (scan line R 2) (line change scan r), and The projection positions are sequentially scanned in the x direction with respect to the scanning points R 2 1 to R 2 n of the second row. Such scanning is performed up to the last scanning point R mn of the last row (scanning line R m).
In this case, as the scanning trajectory information of the scanning points R 1 1 to R mn arranged in m rows and n columns, the projection order “R 1 1 → R 1 2 →... → R 1 n → R 2 1 → R 2 2 →... → Rmn ”is obtained.
Assuming that the array information (m rows and n columns) of the scanning points is included in the scanning control information, the scanning trajectory information is obtained by sequentially setting parallel scanning lines R 1 to R m in the x direction as shown in FIG. It is information that represents the scanning trajectory of the target moving.
  Obviously, two or more different scanning trajectories can be defined even if the arrangement of the scanning points is the same. For example, even in the m-by-n arrangement shown in the figure, a scanning trajectory that scans odd-numbered rows in the x-direction and scans even-numbered rows in the -x-direction can be applied.
A scanning trajectory in which scanning is performed along n scanning lines along the y direction can also be applied.
When scanning in the direction intersecting with each of the plurality of scanning lines (scanning also in the direction intersecting with the main scanning direction), information representing the trajectory of the scanning can be included in the scanning trajectory information.
Further, even when arrangement information and interval information of a plurality of scanning points are not included, scanning trajectory information can be formed. For example, it is possible to form scanning trajectory information representing scanning patterns (types) such as zigzag, oblique scanning, spiral, and concentric circles.
In general,
Pixels (pixels) are two-dimensionally arranged on a display screen of a display device such as an LCD, and a coordinate value of a two-dimensional coordinate system is assigned in advance to each pixel.
When displaying a visual target and a fixation target on L CD, the main control unit displays an image at a predetermined position on the display screen by designating pixels that form the image of the visual target and the fixation target.
At this time, the main control unit determines the display position of the visual target and the fixation target image according to the operation on the changeover switch and the position adjustment switch of the operation panel.
Next, an example of a process for generating projection position control information will be described.

  Claim 5 A computer,
  The spatial separation ability of the central visual acuity is high (FIG. 1, central visual acuity 14), and the spatial separation ability of the central external visual acuity is low (see central external vision 6 of FIG. 1). As the visual field is farther from the center, the number of pyramidal cells decreases, so the spatial separation ability decreases. In areas with low spatial resolution (see FIG. 1, external visual acuity 6), the dynamic visual target speeds up the examination. However, since the dynamic visual target moves at a constant speed in the horizontal direction, the inspection accuracy is uniform. Central vision and non-central vision functions can be inspected uniformly. It is possible to perform a test that is not affected by the judgment of the writer and the preconception about the visual field of the subject.

If you are not a subject, you will not know the state of the dark spot. Even the test subject cannot recognize the shape and size of the dark spot around the visual field other than the fixed viewpoint and the central part of the visual field (see the part 4 where the dark spot and the blind spot are connected in FIG. 1).

  16. A computer,
  Inspection can be speeded up by using dynamic targets for static targets. Humans can respond quickly to moving objects. Dynamic visual targets are less susceptible to visual familiar afterimages than static visual targets, and the examination time can be shortened by reducing the subject's confirmation judgment time for the appearance of the visual target. Due to the high sensitivity of the dynamic target to the human static target, the subject will not respond to the reappearance of the dynamic target even after a certain amount of areas, such as dark spots, where the spatial separation ability is low. High speed response is possible (see 16 in FIG. 1).

The subject can hardly recognize what the scan results are due to fixation target gaze, but can recognize a very bright display near the dark spot and blind spot area, so It has an effect of greatly reducing, and can prevent a decrease in visibility due to a familiar afterimage (see FIG. 2). By bringing about a change, the subject's concentration can be maintained. The subject can roughly recognize the progress of the examination by peripheral vision.

  27. A computer,
  In the conventional perimeter, the examination space separation ability is rough, the shape of the dark spot blind spot of the examination result is very rough and difficult to understand, and the examination time is very long. The present invention makes it possible to accurately display the shape of the dark spot blind spot of the subject on the display, and to adjust the movement of the target passively and passively, which has the feature that the examination time can be greatly shortened because of the contour extraction method. A visual field inspection method that enables high-speed contour extraction of the visual field functional state state to be shown on the display, and a program B for functioning therefor.
  28. A computer,
  A visual field inspection method used in the program B according to claim 27 (refer to FIG. 10 for a visual field inspection result). In visual field inspections in which the static target is moved sequentially in the horizontal right direction every time it is confirmed that the subject has recognized, the subject will have a similar button press response in the field where the visual field is not impaired or in the dark spot blind spot field. Will continue. However, since the subject learns and memorizes the same button press response and uses that memory in the subsequent response process, even if the subject recognizes that the target is not visible, the person who uses the memory rather than recognition However, it is easy to make a wrong button response as if the target was visible. Even if the subject carefully presses the button so as not to make an incorrect response regarding the target recognition, immediately after making the same button response several times, the tendency to make an incorrect response is very high, In the case of a rough visual field inspection, the error due to the mistake is large. In addition, subject's carefulness to avoid false button responses leads to an increase in examination time. Therefore, in the visual field inspection method using the program B of the present invention, in order to solve such a problem, unless the change in the visual sensitivity in the visual field is recognized, the subject keeps pressing the button to set the visual target in advance in the computer. , Move the button dynamically only when it recognizes the change in visibility, make the dynamic target a static target, and the subject actively moves the target in the opposite direction. A method is adopted in which the position is adjusted by moving it in the forward direction and the visibility change point is determined by pressing the space key. In areas where the visibility does not change, the subject does not respond by pressing the button every time it confirms that there is no change, but moves the dynamic target to the inside of the dark spot or blind spot area to some extent. This is a method for speeding up the visual field inspection by continuing to press the target right direction movement button. Since some position determination error is allowed at that time, the moving speed of the dynamic visual target can be set to be somewhat high. When the subject recognizes that the dynamic target has entered the dark spot or the blind spot but the dynamic target is still visible, the subject releases the target rightward movement button once. The dynamic target becomes a static target. Requesting the subject to respond to the dark spot or blind spot at the moment when the visibility changes changes the response time to human stimuli, especially immediately after the same stimulus is repeated repeatedly. The response is quite unreasonable because the learning and memory effect of a response that has been repeated several times so far appears strongly and tends to be an incorrect response. However, it is easy for a subject to recognize immediately after an error response that an error response has been made to a different stimulus after the same stimulus repeated several times. After that, since the subject actively determines the position where the visibility changes due to the dark spot or blind spot area while moving the target slightly to the left and right and correcting it, the shape of the extracted contour is very It is accurate and faithfully reflects the visual function status, such as the subject's dark spot and blind spot. The test result is shown on the display and is intuitively easy to understand (see FIG. 10). Since the subject only needs to respond to only the visibility change contour, by adjusting the size of the visual target and the moving speed of the visual target, a high-speed inspection with an inspection time of 5 minutes or less for a one-side visual field is possible. . Although it is a high-speed inspection that is impossible to achieve with a conventional perimeter, if the inspection result is only a contour, a diagram of a full-field retinal function scan visual field inspection result submitted on June 18, 2007 (FIG. 11, − 1), and an accuracy equivalent to that of the very detailed visual field inspection result (see FIG. 9) according to claim 23 for actively setting the inspection range. In the method of the present invention, in order to speed up the entire visual field inspection, the dynamic target is used at a moving speed set in the computer in advance, and when the one-line inspection in the horizontal right direction is completed, the next line inspection is started from the left end. The subject performs passively under control, but in order to accurately extract the contours of the visual function changes such as dark spots and blind spots, the dynamic visual target is changed to a static visual target around the visual sensitivity change part, and the visual sensitivity changes This is a method in which the subject actively adjusts the target position in order to accurately extract the contour. Because it is a program, it is possible to refine the inspection result diagram or increase the inspection speed by adjusting the size and moving speed of the computer-controlled dynamic target.
  29. A computer,
  By enlarging the target or inputting the target into the computer, the geometric shape of the target passing dynamically can be observed around the blind spot. In addition, since the target can be input by a computer, when a character or the like is used as a target, the degree of character recognition in the visual field can be observed. 28. It is possible to perform various observations related to the visual field visual function, and it is possible to extract an outline of an observation result and a visual sensitivity change position at a high speed, which can be intuitively illustrated on a display.

  31. A computer,
  The subject aims at speeding up the visual field inspection by adopting a method in which the subject is required to respond only to the dynamic visual target moving in the horizontal right direction when the change in the visibility is recognized. It is easy for the subject to recognize the appearance of discontinuous positions of the visibility on the dynamic target moving in the horizontal right direction. The visual field inspection method used when using the program B according to claim 27, which is a method using a characteristic that sensitivity to a human discontinuity start point is sensitive. Unless the change is recognized in the visibility, the subject keeps pressing the right direction movement button → and does not respond one by one, so the examination time can be shortened. The subject can easily recognize that he has gone too far to the right of the visibility change position. After such recognition, the subject can accurately determine the discontinuity of the visibility while actively moving the visual target around the discontinuity of the visibility with the left movement button ← or the right movement button → Press to record the position.
  32. A computer,

In the case of full-field measurement, the horizontal visual field inspection was speeded up precisely by using two points of the dynamic visual target and the static visual target alternately.Move horizontallyWith the position of the dynamic target and the static target in the vertical direction fixed to the center of the display, the test result is sequentially generated from the bottom row by sequentially moving the fixed target vertically downward. (See FIG. 16). Since the inspection method uses two targets alternately, it functions as a full-field retinal function scan that dynamically increases the inspection speed in the external vision and statically increases the inspection details in the macula. Program 1 for causing The spatial resolution of central vision is high, and the spatial resolution of external vision is low. As the visual field is farther from the center, the number of pyramidal cells decreases, so the spatial separation ability decreases. In areas with low spatial resolution, dynamic visual targets speed inspection. However, since the dynamic visual target moves at a constant speed in the horizontal direction, the inspection accuracy is uniform. Central vision and non-central vision functions can be inspected uniformly. It is possible to perform a test that is not affected by the judgment of the writer and the preconception about the visual field of the subject. Accumulating information on the degree of spatial separation detected by dynamic targets in the test record as static targets by continuously linking dynamic targets and static targets without any spatial separation be able to. The test result is a retinal function two-dimensional scan. (See FIG. 16 etc.).
  47. A computer,
  After executing the visual field retinal function scanning and program 1, the frequency distribution with the spatial resolution as a class can be displayed on the display as a columnar graph (see FIG. 18 and the like). The frequency distribution graph is displayed in the order of the spatial resolution.
  In the case of the program 1 of the present invention.
  The spatial resolution capability distribution graph is a visual function distribution (see FIG. 16, etc.) that is spatially arranged and expressed in the two-dimensional direction in the full-field retinal function scan result diagram, and the spatial resolution capability in the one-dimensional direction. (See FIG. 18 and the like). By observing the same distribution from two different viewpoints, it was possible to infer whether the distribution generation process of one (for example, full-field retinal function scan result diagram) was plausible and appropriate.
  From the spatial separation ability frequency distribution graph, it can be seen that the central visual acuity is restricted by the visual information processing capacity (see 1 in FIG. 18), and the external visual acuity is restricted by the retinal area (see 2 in FIG. 18). . Due to the limitation of visual information processing capacity and the optimized balance of maximal spatial resolution with respect to the retina area, both sides of the frequency distribution graph have an increasing exponential function on the left side and a decreasing exponential characteristic on the right side. The resolution frequency distribution graph shows a single peak shape. In particular, in the central visual acuity, the frequency of the class having a large spatial separation ability is remarkably reduced, and the frequency is expressed in a columnar graph in a state where the visual information processing capacity is strongly restricted. If the examination-side visual field frequency distribution graph is displayed over the opposite-side frequency distribution graph as a background, it is possible to infer a spatial resolution class in which the visual function in the examination-side visual field is degraded or the visual field is missing. . A spatial resolution class that constitutes a visual field defect area such as a dark spot appears as a frequency in a class having a low spatial resolution (see 5 in FIG. 18). In addition, the spatial separation power distribution graph of the contralateral visual field may provide a contrasting background distribution for examining the visual field condition for the examination visual field (see FIG. 14).

  48. Full-field retinal function scan according to claim 47, wherein the inspection result becomes a beautiful scan diagram of sequential two-dimensional gray scale display, which is displayed on the display from during the inspection, and can display a spatial separation power distribution graph that reduces the monotonicity of the visual field inspection. Program 1 to function as
  49. A computer,
  In the case of the program 1 of the present invention.
  Two-point target system for full-field inspection. Block the eyes that will not be inspected. First, the subject gazes at the fast flashing fixation target on the display with the eye performing the visual field inspection. displayCenter part with respect to the vertical direction at the left endThe dynamic visual target A appears while moving in the horizontal right direction. When the subject can recognize the movement of the dynamic visual target A in the visual field, the button is pressed. The dynamic target A becomes a static target A dash at that position. With the static target A dash being displayed, the dynamic target B having the same shape and size starts to move in the right horizontal direction at the same speed from the position of the static target A dash. Press the button or space key when the subject recognizes the two points of the static target A dash and the dynamic target B, or the movement of the dynamic target B in the field of view, based on the spatial separation ability. . The static target A dash disappears from the display, and the dynamic target B becomes the static target B dash at the position where the button is pressed. With the static target B dash displayed, the dynamic target C appears from the position of the static target B dash and starts moving in the horizontal direction at the same speed to the right. The button or the space key is pressed at the stage where the appearance of the dynamic visual target C with respect to the static visual target B dash is recognized by the subject's spatial resolution or the movement of the dynamic visual target C is recognized in the visual field.
  The visual function of the retina can be scanned by repeating similar processing. The dynamic visual target moves to the right end, the visual field inspection of that row is completed, and when the button or space key is pressed, the dynamic visual target appears from the left end of the same stage, but the fixation target is one level lower The field of view scan continues in a moving manner. The entire field of view of one eye can be scanned by repetition.
  Since the central part of the visual field and the macular part have high spatial resolution, the distance between the static visual target and the dynamic visual target when the button or the space key is pressed becomes short. In the central foveal portion, the distance between the static visual target and the dynamic visual target is the shortest. On the display, the degree of the distance between the static visual target and the dynamic visual target is converted into a color shading and displayed as a shading two-dimensional scan diagram. When the distance between the static target and the dynamic target is long, the display is divided into bright colors, and when the distance between the static target and the dynamic target is short, the display is divided into dark colors. . The present invention47. Program 1 according to claim 47Then, it is possible to measure with an accuracy of about 2 minutes or less, such as the effective visual cell density of the entire visual field of one eye, but the examination time is short regardless of the high precision of the examination.
  Since humans gain sight through the optic nerve and brain, the ophthalmoscope does not know the state of higher visual function than the retina. If you are not a subject, you will not know the state of the dark spot. The subject cannot recognize the fixed point, the shape and size of the dark spot around the visual field other than the central part of the visual field. The present invention47. Program 1 according to claim 47Makes it possible to faithfully reproduce the dark spot blind spot shape that can be transmitted from the retinal photoreceptor cells to the visual cortex on the display. 48. The retinal function scan according to claim 47, wherein the retina in the eye, the area where the optic nerve does not function effectively, and the area where the visual function is reduced (see 25 in FIG. 16) can be reproduced and clearly displayed on a display like a map. Program 1 for causing
  Intuitively understand the severity of the dark spot area relative to the fixation point and the macular area. As a result of the measurement, the difference in resolution of the visual field was expressed in detail as a two-dimensional scan, and the shape of the visual field defect part and the shape of the blind spot were displayed on the computer screen. The state of enlarged blind spot diameter due to optic nerve depression or the like can be displayed. In addition to visual field defects and dark spots, areas that have slightly damaged pyramidal cells, reduced cone density, or reduced cone function can be displayed on the display as a two-dimensional scan on a gray scale. (Refer to 25 in FIG. 16, etc.) Program 1 for causing a full-field retinal function scan according to claim 47 to function.
  Since the present invention can detect a spatial resolution of about 2 minutes or less, it cannot be found in a conventional perimeter having the disadvantage that a field defect within several degrees cannot be detected such that the connection from the dark spot to the blind spot becomes gradually thinner. A glaucoma characteristic of a dark spot (see 26 in FIG. 16) can be detected. It is possible to detect and display the relationship between Bjerrum area dark spots and blind spots such as glaucomatous visual field defects and horseshoe-shaped dark spots.
  48. The program 1 for functioning as a full-field retinal function scan according to claim 47, capable of detecting and displaying a shape of a visual field defect field such as a laser retinal property in a field far from the fovea.
  50. A computer,
  In the case of the program 1 of the present invention.
  By using two points of a static visual target and a dynamic visual target alternately and continuously, recognition of the dynamic visual target by the subject becomes a central work for the off-center visual field, and the examination time is shortened.
  In general, visual recognition of external visual acuity, especially 2 visual recognition, is easy to use with static visual targets because the ease of recognition varies considerably depending on the length of time used to recognize them. It is difficult to perform an objective inspection.
But,In the case of the program 1 of the present invention.
  By using a dynamic visual target with central visual acuity and a method that responds when the movement of the visual target is recognized in the field of view, fluctuations in the time required for visual recognition in the external visual acuity are detected. It is possible to considerably reduce the phenomenon that affects the degree of spatial separation.
  In the case of the program 1 of the present invention.
  In the macular region, which is an important part of vision, static target recognition is a central task, and the degree of visual function can be inspected in detail and slowly.
  This is because the degree of target recognition of the central visual acuity is hardly affected by the length of time until recognition.

  51. A computer,
  Inspection can be speeded up by using dynamic targets for static targets. Humans can respond quickly to moving objects. Dynamic visual targets are less susceptible to visual familiar afterimages than static visual targets, and the examination time can be shortened by reducing the subject's confirmation judgment time for the appearance of the visual target. Due to the high sensitivity of the dynamic target to the human static target, the subject will not respond to the reappearance of the dynamic target even after a certain amount of areas, such as dark spots, where the spatial separation ability is low. High speed response is possible. 48. The program 1 for functioning as a full-field retinal function scan according to claim 47, wherein a horizontal movement of the dynamic visual target having a certain distance, its speed, etc. considerably reduce the monotony of the conventional perimeter.

The program 1 for functioning as a full-field retinal function scan according to claim 47, wherein the fixation point fixation target increases the fixation point fixation degree of the subject by performing high-speed two-color alternate blinking. With a non-flashing fixation target such as a conventional perimeter, precise gaze is difficult due to a visual afterimage.
  53. A computer,
  Since the subject performs fast flashing fixation point fixation target gaze, there is a case where the dynamic target cannot be recognized even if it reaches the right end of the display. In such a case, the dynamic visual target reaches the right edge of the display, the inspection of that line is in the end state, and a mark indicating that it is waiting for the inspection of the next lower line is marked with a fast flashing fixation point part. Are displayed side by side on the fixation target. After the subject recognizes the mark on the fixation point fixation target portion, the examinee can start the examination of the next lower row by pressing the button or the space key. 48.

  After the field-of-view inspection is completed, the above mark is displayed, and each time the button or space key is pressed to start the next-line inspection, the result of the visual field function two-dimensional scan up to that point However, only the inspected area from the bottom line is displayed instantaneously. The subject can hardly recognize what the scan results are due to fixation target gaze, but it can recognize a bright display display in the vicinity of the dark spot and blind spot area, so that the subject is very tired It has the effect of decreasing, and can prevent a decrease in visibility due to a familiar afterimage. By bringing about a change, the subject's concentration can be maintained. The subject can roughly recognize the progress of the examination by peripheral vision.
  It is also possible to adjust so that the scan results are not sequentially displayed on the display during the inspection by the program. The program can be adjusted in various ways such as the size of the target. The target moving speed and moving direction can be adjusted in various ways by the program, so the inspection time can be adjusted. 48.

By visualizing the visual field state of the subject at home, explanation of the visual field state of the subject can be facilitated. 48. The program 1 for functioning as a full-field retinal function scan according to claim 47, wherein the inspection output result is beautiful, and the visual field inspection is performed for a certain period of time, and the result can be relaxed by looking at the output.
  57. A computer,
  By actively selecting the inspection range in advance, a very detailed visual visual function test can be performed, and the result can be clearly displayed on the display (see FIG. 20). The inspection range is the program 1 according to claim 47 or the high-speed inspection method (program according to claim 65).3,reference. ), A part where an obstacle is detected in the visual field function, or a range to be observed (blind spot etc.) can be selected. 61. A program for functioning as set forth in claim 60, wherein a test result having a very detailed spatial separation ability can be obtained in a short time by a method of performing visual field inspection with a limited range. (See 200 and 202 in FIG. 20).
  58. A computer,
  The shape of the connection area from the dark spot to the blind spot, which is said to be characteristic of glaucoma and macular neovascularization that cannot be detected by a conventional perimeter, can be shown in detail on the display (see 205 in FIG. 20).

  59. A computer,
  In the conventional perimeter, the examination space separation ability is rough, the shape of the dark spot blind spot of the examination result is very rough and difficult to understand, and the examination time is very long. The present invention makes it possible to accurately display the shape of the blind spot of the subject on the display, and to adjust the movement of the target passively and passively, which has the feature that the examination time can be greatly shortened because of the contour extraction method. 66. A visual field inspection method that enables high-speed contour extraction of the visual field functional state state to be shown on the display, and a program 3 for functioning as described in claim 65 for that purpose.
  60. A computer,
  For program 2.
  The ratio of the visual field defect area to the visual field inspection area can be displayed in%. (See FIG. 20).
A conventional perimeter has not been able to quantitatively evaluate the field defect area with respect to the field inspection range.
  By selecting a local visual field centering on a fixation target important for character recognition as an inspection range, the degree of visual field defect with respect to reading comprehension can be evaluated quantitatively in%. (See 200 and 202 in FIG. 20).
  The retinal area, which has a high density of pyramidal cells, which is important for reading and recognizing text, is the foveal area, and the field-of-view inspection range can be extremely localized. Achieved. (See 200 and 202 in FIG. 20).
  With familiar% display, the state of visual field loss is intuitively understood.
  In addition to text reading / recognition recognition, a visual field inspection range such as a dark spot to a blind spot can be actively selected in advance, and the extent of the visual field defect area relative to the inspection area can be quantitatively evaluated objectively. (See 205 in FIG. 20).
  The degree of seriousness of the dark spot area relative to the fixed viewpoint and the fovea is displayed as a percentage, and can be explained intuitively.
  For program 2.
  Regarding the method of selecting the corresponding visual field inspection range in measuring the degree of visual field defect impairment for reading / recognition of sentences in% units, for example, a character permutation similar in character shape in terms of spatial separation, such as yellow English, For example, the subject can actively move it left and right and up and down, and the range in which the subject can distinguish yellow and English is determined as the examination range. How to select the inspection range from the foveal point of view.
  Alternatively, it is possible to select a horizontal inspection range and a vertical inspection range by moving the target target in the horizontal direction to the left and right for horizontal writing and the vertical movement for vertical writing. In that case, the vertical inspection range and horizontal inspection range are determined by the font size of the target. In this method, it is considered that the degree of visual field deficit with respect to reading comprehension is expressed with considerably different numbers in the case of reading comprehension for horizontal writing and for reading comprehension of vertical writing. This is because the traveling of the optic nerve axon has horizontal directivity. (See 200 and 202 in FIG. 20).
  The importance of reading range recognition for horizontal writing and vertical writing in the horizontal and vertical directions, respectively, is symmetrical from the left and the right from the viewpoint of the retention of memory in human reading. I don't think so. (See 202 in FIG. 20).
  61. A computer,
  The program according to claim 65.3Visual field inspection method used in In visual field inspections in which the static target is moved sequentially in the horizontal right direction every time it is confirmed that the subject has recognized, the subject will have a similar button press response in the field where the visual field is not impaired or in the dark spot blind spot field. Will continue. However, since the subject learns and memorizes the same button press response and uses that memory in the subsequent response process, even if the subject recognizes that the target is not visible, the person who uses the memory rather than recognition However, it is easy to make a wrong button response as if the target was visible. Even if the subject carefully presses the button so as not to make an incorrect response regarding the target recognition, immediately after making the same button response several times, the tendency to make an incorrect response is very high, In the case of a rough visual field inspection, the error due to the mistake is large. In addition, subject's carefulness to avoid false button responses leads to an increase in examination time. Therefore, the program according to claim 65 of the present invention3In the visual field inspection method by use, in order to solve such a problem, unless the change in the visibility in the visual field is recognized, the subject keeps pressing the input button and dynamically moves the visual target at a speed set in the computer in advance. Move and release the button only when the change in visibility is recognized, the dynamic target becomes a static target, and the subject actively moves the target in the opposite direction or moves in the forward direction Adjust the position, etc.Visibility change point,Use a method to confirm by pressing the space key. In areas where the visibility does not change, the subject does not respond by pressing the button every time it confirms that there is no change, but moves the dynamic target to the inside of the dark spot or blind spot area to some extent. This is a method for speeding up the visual field inspection by continuously pressing the input button. Since some position determination error is allowed at that time, the moving speed of the dynamic target can be set at a high speed. When the subject releases the input button once the subject recognizes that the dynamic target has entered the dark spot or blind spot, but the dynamic target is still visible, the high speed The dynamic visual target moving to becomes a static visual target. Requesting the subject to respond to the dark spot or blind spot at the moment when the visibility changes changes the response time to human stimuli, especially immediately after the same stimulus is repeated repeatedly. The response is quite unreasonable because the learning and memory effect of a response that has been repeated several times so far appears strongly and tends to be an incorrect response. However, it is easy for a subject to recognize immediately after an error response that an error response has been made to a different stimulus after the same stimulus repeated several times. After that, because the subject actively determines the position where the visibility changes due to the dark spot or blind spot area by moving the target to the left and right at low speed and correcting it, the shape of the extracted contour is very And accurately reflects the visual functioning state of the subject, such as the subject's dark spot and blind spot. The inspection result is shown on the display and is easy to understand intuitively. Since the subject only needs to respond to only the visibility change contour, by adjusting the size of the visual target and the moving speed of the visual target, a high-speed inspection with an inspection time of 5 minutes or less for a one-side visual field is possible. . A high-speed inspection that cannot be realized by a conventional perimeter, but if the inspection result is only a contour, a full-field retinal function scan program 1 view inspection result diagram (see FIG. 16 and the like) and claims. Actively set the inspection range described in 60Diagram of results from very detailed visual field inspection program 2(See 205 in FIG. 20). In the method of the present invention, in order to speed up the entire visual field inspection, the target is moved to a high speed at a speed set in the computer in advance and is used dynamically. The subject is passively controlled by computer control from the left end.However, in order to accurately extract the contours of visual function changes such as dark spots and blind spots, dynamic targets are static targets in the vicinity of the change in visibility. In addition, by using a dynamic visual target that moves at a low speed, the subject actively adjusts the visual target position in order to accurately extract the visibility change contour. Because it is a program, it is possible to refine the inspection result diagram or increase the inspection speed by adjusting the size and moving speed of the computer-controlled dynamic target. (See FIG. 15, FIG. 17, etc.).
  62. A computer,
  The program according to claim 65.3The field-of-view inspection method enables the inspection of the test subject's judgment on the dark spot area of the subject and the inspection not affected by preconceptions, and the objectivity of the test result diagram to the recorder is maintained.
  63. A computer,
  Invention program3in the case of.
  The subject aims at speeding up the visual field inspection by adopting a method in which the subject is required to respond only to the dynamic visual target moving in the horizontal right direction when the change in the visibility is recognized. It is easy for the subject to recognize the appearance of discontinuous positions of the visibility on the dynamic target moving in the horizontal right direction. 66. A visual field inspection method used when using the program according to claim 65, which is a method using a characteristic that sensitivity to a human discontinuity start point is sensitive. Unless the change is recognized in the visibility, the subject keeps pressing the input button and keeps moving the dynamic target at a high speed, and does not respond one by one, so the examination time can be shortened. The subject can easily recognize that he has gone too far to the right of the visibility change position. After such recognition, the subject accurately determines the discontinuity of the visibility while actively moving the target around the discontinuity of the visibility and confirming it with the left movement button ← and the right movement button →. Press the space key to record the position.
  64. A computer,
  The program according to claim 65.3In the visual field inspection method using the subject, the subject's target recognition confirmation trap time is converted into the subject's active position adjustment time, and the subject's judgment trap time that occurs in order to correct the target recognition is zero. As a result, the visual field inspection process is speeded up and at the same time the accuracy of contour extraction is achieved. Since it is a method that can be inspected while adjusting the position by recognizing that the target has moved too far in the right direction, etc., the temporal response during contour extraction by the subject The recording position error due to delay or the like can be reduced to zero.
  65. A computer,
  Invention program3in the case of.
  The response method of the subject to the visual field inspection of the present invention is not limited to the visual field, and can be applied to general searches for extracting features of interest from a wide range at high speed. The visual field inspection result is easy to understand and interesting because it is a feature contour extraction type (see FIGS. 17 and 15). By appropriately setting the size of the target, the moving speed, etc., it is possible to realize a one-eye full visual field inspection time of 5 minutes or less (see FIG. 17 and the like).
  The program of the present invention determines the visibility change position with respect to the target in units of rows while dynamically moving the target in the horizontal right direction from the upper left corner of the display while keeping the center of the display as a fixed viewpoint. After scanning the vertical contour of the visibility change area by repeating the above, determine the visibility change position in units of columns while dynamically moving the visual target vertically from the lower left corner of the display. This is a method of scanning and extracting the horizontal contour of the visibility changing field by repeating in the right direction.
  The output to the display is a method of synthesizing the vertical and horizontal contours. As a result, the contour of the visibility changing area scans only the vertical contour by dynamically moving the visual target in the horizontal right direction. It becomes clearer (see FIG. 21) than when extracted (see FIG. 15 and FIG. 17).
  program3Because the target that is used has a certain size, if the subject lacks the visual target, such as a dark spot or a blind spot, the position of the target is visible If the change position is determined in advance, it is considered that the determination time for determining the visibility change position in the target recognition can be significantly reduced.
  For example, FIG. 21, FIG. 15, FIG. 17, and the like show the test results when the subject has determined in advance that the visual loss is about 50% due to the visual field defect field to be the visibility change position. FIG.
  In the programs 1 and 2 with small targets, the determination time for the degree of target loss was almost zero when determining the visibility change position, and thus it was not necessary to perform such consideration.
  However, in visual field inspection, learning effects regarding the shape of dark spots and blind spots, which are accumulated according to the frequency of inspection and are effective for the accuracy of the inspection, can occur, and various features of visual function can be extracted. The subject can select such as the degree of target defect.
  In addition, when the degree of target loss to be set as the visibility change position is clearly determined in advance, as is known from the visual field inspection result in FIG. Because there are unequal parts (see 62 and 66 in FIG. 21),By increasing the visual field inspection time, it is possible to accurately observe a phenomenon in which the peripheral visual field is sequentially moved, such as a blind spot position.
  Invention program3in the case of.
  The method of responding only to the position where the subject recognizes the change in the visibility in the visual field inspection is not limited to the visual field, and is a method that can be applied to a general search for extracting features of interest from a wide range at high speed. Part of a method that attempts to actively change the information processing speed adaptively to the characteristics of the target by processing the essential part at a low speed and processing the non-essential part at a high speed. It is. (See FIGS. 20, 21, 15, and 17.) The importance of this method stems from the phenomenon that it is not so easy for humans to flexibly convert their information processing speed according to the target.
  66. A computer,
  The results of the visual field inspection are the program 1, the program 2, and the program according to claims 47, 60 and 65, respectively.3The shape of the visual field defect part and the shape of the blind spot are displayed on the computer screen. Intuitively understand the severity of the dark spot area relative to the fixation point and the macular area. It is possible to display in detail such as the blind spot diameter enlarged state due to optic nerve depression.
  48. The program according to claim 47, the program according to claim 60 and the program according to claim 65, the program 2, and the program according to claim 47.3By using, it becomes possible to explain intuitively in a very short time.
  66. The program according to claim 65, wherein the visual field functional state is shown in a very detailed manner on the display by the method of actively selecting a field to be inspected according to the present invention.3Can detect a considerably fine spatial resolution, so that the connecting portion from the dark spot to the blind spot becomes gradually thinner, the glaucoma characteristic of about several minutes, etc., which cannot be detected by the conventional perimeter accuracy (FIG. 21). 62.) can be detected at a high speed of about several minutes. The relationship between Bjerrum area dark spots and blind spots, such as glaucomatous visual field defects and horseshoe-shaped dark spots, can be detected and displayed in great detail by the horizontal and vertical contour extraction scanning method.
  The visual field inspection result diagram by the program 2 according to the present invention and claim 60 shows in detail the bending state of the dark spot area (see 205 in FIG. 20), which is very helpful when estimating the origin of the dark spot. become. The result of the inspection of the conventional basic perimeter does not show the degree of bending of the dark spot area.
  The program according to the present invention, claim 653In addition, the visual field inspection method makes it possible to extract the contours of the dark spots in detail at high speed and display them on the display (60 in FIG. 21; see FIGS. 15 and 17). It is very helpful when estimating the origin of dark spots. The result of the inspection of the conventional basic perimeter does not show the degree of bending of the dark spot area.
  According to the present invention, by virtue of the method of actively selecting the field to be inspected, the visual field function state is shown in a very detailed manner on the display. It can detect and display a very detailed shape of the field defect area such as laser retinal.
  The present invention, high-speed contour extraction of visual field functional state by passively moving and adjusting the target,
66. The program of claim 65 illustrated on a display.3In addition, the visual field inspection method makes it possible to detect and display the contour of a field defect region shape such as a laser retinal region in a region away from the fovea at a very high speed.
  67. A computer,
  The program 2 according to claim 60 can shorten the inspection time by actively selecting the inspection range. 66. Program according to claim 65, on the other hand, contour high-speed extraction type3In addition, in the visual field inspection method, the retinal visual function is impaired or the features to be observed are not discontinuous. By using a high-speed dynamic visual target, passive high-speed visual field inspection is possible, and the retinal visual function is impaired or observed. Areas with discontinuous features can convert dynamic targets to static targets and perform active visual field inspection at low speed. Since the subject responds only to the contour portion, the examination time is greatly shortened.
  The program according to claim 65.3In this visual field inspection method, when a subject recognizes a discontinuity in visibility, a dynamic target moving at high speed is temporarily converted into a static target. To adjust the position, the static target is converted into a dynamic target that moves at low speed. Since the visibility change recognition position is adjusted back and forth using a low-speed dynamic target, the position is determined accurately. After the position is determined, the low speed dynamic target is converted into a high speed dynamic target. In addition to the position for recognizing changes in visibility, even if there is a target inside the field such as a dark spot or blind spot, the test does not require a response from the subject one by one. Shortened to Since the visibility invariant portion uses a high-speed dynamic target, the inspection time is shortened from the viewpoint of the target recognition time.

  A method for extracting features of interest from a wide-range search object at high speed, or a general method for reducing the driving force of the work when it is necessary to sequentially understand or recognize a wide-range object. A method in which the search speed, understanding, or recognition speed is changed actively depending on the search or understanding target, and the search error, understanding, or recognition error can be greatly reduced. If it is a search, an object that diverges from interest and an object that can be inferred from tradition perform considerably high-speed processing. If it is understanding, understanding of the object that can be inferred from the memory is performed at a considerably high speed. However, if it is a search, it will be a very slow process for an object of interest, a target that deviates from tradition, and if it is an understanding, an object that cannot be inferred from memory will take a considerable amount of time by taking a sufficient amount of time. , A way to try to achieve understanding or recognition. In understanding and recognizing, humans cannot understand the memory collation search time for understanding and recognizing flexibly and actively according to the object. Mistakes in understanding or recognition because it does not take the necessary reaction time. In understanding the object, the part inferred from the memory can be understood at high speed, but the part that cannot be inferred from the memory cannot be understood at all, but the superficial processing is continued, the uncertainty of definition accumulates in the processing, and the work is promoted. Derived from a phenomenon in which power is often reduced.
  Since all of the programs of the present invention have simple inspection methods, it is possible to easily experience visual field inspection, observation of blind spots, etc. even at home. By visualizing and quantifying a subject's visual field state at home, explanation of the visual field state of the subject can be facilitated. In any program, since the inspection output result is beautiful, it is possible to relax by performing a visual field inspection for a certain period of time and looking at the output.
  69. A computer,
  A visual field area that has a spatial resolution enough to recognize characters can be detected at high speed, and the percentage of the visual field defect area such as a dark spot relative to it is intuitively displayed on the computer display as a visual function impairment level in character recognition. A program to make it function as displayable.
  In order to facilitate gaze, the visual field inspection range is determined by a method in which a target composed of letters, symbols, etc. is dynamically orbited slowly and circularly around a fixation target straddling two colors alternately.
  First, the character target is around the fixed viewpoint.
The subject increases or decreases the circular orbit radius of the character target. A method that sets the radius of the visual field inspection range as the radius that prevents the subject from clearly recognizing the target as a character in terms of resolution.
The selected circular visual field inspection range is a very important visual field for character recognition of the subject.
  Perform a detailed visual field inspection for the area.
  Since the inspection range is limited from the viewpoint of character recognition, the inspection can be performed in a very short time but in detail.
  In addition, when the target only moves linearly, the position of the dark spot becomes an obstacle, and setting the upper limit or lower limit of the inspection range from the viewpoint of character recognition may be quite difficult for the subject.
  However, the inspection range can be easily determined in a very short time by using a method of changing the orbital radius of the dynamic character target.
  The result is a very constant value.
  If the resolution is reduced to some extent, an inspection time of 5 minutes can be achieved, but the resolution is sufficiently practical.
  The ratio of the visual field defect area to the visual field inspection range set by the dynamic character target that performs the circular orbit can be displayed numerically by intuitive%.
  The amount of obstacles due to visual field defects such as dark spots for character recognition can be displayed in quantity on the display.
  The accuracy can be confirmed by the consistency of several-degree inspection.
Field inspection range setting method from the viewpoint of character recognition of the program that can display the visual field defect level in character recognition.
  70. A computer,
  A very detailed examination is possible by reducing the size of the target.
It is easy to understand because the visual field defect state can be displayed on the display.
A program for selecting an inspection range from the viewpoint of character recognition, performing visual field inspection at high speed, and functioning so that the visual field defect level and visual field defect state can be clearly displayed in detail on the display.
  The program for functioning as described in Claim 69 which can display% of the seriousness of visual field defect | deletion for a test subject from a viewpoint of character recognition.
  71. A computer,
  A program A, a program B, a program C, and a program D of the present invention capable of detecting the blind spot position in the visual field of both eyes and the size of the blind spot at high speed and displaying them on the display.
  The blind spot position of both visual fields and the size of the blind spot extracted by the circular trajectory can be displayed on the display side by side (see FIG. 27). Program A, program B, program C, program D of the present invention.
  The left-right difference in blind spot diameter can be calculated and displayed on the display in an intuitive manner, for example, the blind spot size of the right eye is 1.06 times the left eye (see 2 in FIG. 27). Program B for causing program A to function.
  The program A of the present invention that makes it possible to intuitively compare the state of the left and right visual fields related to the blind spot with an approximate contour diagram (see 30 and 40 in FIG. 27) and numerals (see 2 in FIG. 27) on the display. Program B for functioning as
  The degree of left / right asymmetry and left / right divergence (see FIG. 27) is information related to retinal stress, glaucoma, etc. in both the blind spot position and blind spot diameter.
  Successful display of the position of the detected blind spot and the transition of the change in the diameter size of the blind spot with respect to the examination time was successfully displayed on the display (see FIG. 26).
  72. A computer,
  72. The program A, program B, program C, program D according to claim 71.
  Blind spot inspection method of the present invention program A, program B, program C, program D.
  For detecting the position of the blind spot, an * mark target (see 25 in FIG. 29) and a dynamic target (see 14, 22 in FIG. 29) that performs two inner and outer circular trajectories around the * mark are used. .
  The blind spot diameter detection is a method in which two inner and outer circular orbit targets (see 14 and 22 in FIG. 29) centering on the mark * are adjusted while changing the trajectory radius.
  For example, when testing is detected from the blind spot of the right eye field.
The left eye field is blocked and the central fixation target is fixed with the right eye.
The subject moves the green * mark near the fixation target to the right using the arrow keys.
Press the enter key at the position where the green * mark disappears.
Determine the position of the right eye blind spot. The green * mark disappears.
The fixation target will continue to be displayed.
The subject continues to stare at the fixation target (see 6 in FIG. 29).
Next, two circular orbits appear on the inner and outer sides around the purple mark (see 25 in FIG. 29) (see 14, 22 in FIG. 29).
The purple * mark appears at the center position of the blind spot detected by the previous green * mark.
  The inner circular orbit (see 22 in FIG. 29) is a green target that dynamically performs a circular orbit.
The outer circular orbit (see 14 in FIG. 29) consists of a red visual target that dynamically performs a circular orbit.
  When trying to conduct a more accurate inspection.
In order to detect the blind spot position more accurately, the purple * mark (see 25 in FIG. 29) is set to appear at a position slightly away from the previous green * mark.
When the purple * mark can be recognized in the peripheral visual field, the subject uses the arrow keys to move the purple * mark to within the blind spot.
  When moving the purple * mark, in the present invention program A, program B, program C, and program D, the two inner and outer circular orbits centered on the purple * mark (see 25 in FIG. 29) are also the same distance and in the same direction. This is a method of moving (see 14, 22 in FIG. 29).
  Two circular orbits (see FIGS. 14 and 22 in FIG. 29) have a function of easily speeding up the approximate diameter detection of blind spots (see 30 and 40 in FIG. 27).
  The detection error of the blind spot diameter can be limited as compared with the case of using one circular orbit.
The blind spot contour radius detection error can be limited within a radial distance difference between the two inner and outer circular orbits.
  For example, when using only the inner green circle orbit.
When adjusting the green circle orbit within the blind spot area, even if the green circle orbit radial distance is made too short by pressing the B key too much, the subject cannot recognize the degree.
This is because the green circle orbit is already within the blind spot area.
  However, as in the present invention program A, program B, program C, and program D, a red circular orbit (centered on the same purple mark *) is located outside a certain distance from the green circular orbit (see 22 in FIG. 29). In the case where there is 14) in FIG. 29, if the radius is made too short, the outer red circular orbit (see 14 in FIG. 29) enters the blind spot area. At that time, since the subject can recognize the defect of the red circular orbit in the field of view, the subject can recognize that the radius has been reduced too much.
The subject can adjust with the H key to increase the radius.
  The blind spot inspection method of the present invention program A, program B, program C, program D is
First, the trajectory radius is decreased by pressing the B key until the inner green circle orbit (see 22 in FIG. 29) falls within the blind spot area and becomes invisible.
However, the position of the outer red circular orbit (see 14 in FIG. 29) is adjusted by adjusting the position and moving radius by pressing the B key or H key so that the subject can see around the blind spot area.
The B key or the H key has a function of reducing and increasing the moving radius of the inner and outer double circular orbits (see 14 and 22 in FIG. 29) by the same distance.
  The subject adjusts the inner green orbit (see 22 in FIG. 29) within the blind spot area and the outer red orbit (see 14 in FIG. 29) outside the blind spot area.
  The blind spot radius detection error can be limited to the radial distance difference between the outer circular track and the inner circular track.
  For more detailed inspection, more accurate blind spot position, and blind spot diameter approximation, set the trajectory radius to B key or H so that the inner green circle orbit (see 22 in FIG. 29) remains slightly around the blind spot. Adjust with key. Adjust the green dynamic target around the blind spot so that the subject can recognize it.
  If the green distribution recognized around the blind spot has a deviation depending on the direction, the subject adjusts it with an arrow key or the like so that the green distribution is as free as possible.
  The green distribution (see 22 in FIG. 29) by the circular orbit dynamic target visible around the blind spot is uniformly distributed, and the corona green distribution with respect to the circumference of the blind spot is averaged to balance the blind spot center position more accurately. It can be detected.
  Thereafter, the orbital moving radius is further reduced and adjusted to such an extent that the green color (see 22 in FIG. 29) becomes invisible due to a blind spot.
The outer red circular orbit (see 14 in FIG. 29) is visible around the blind spot.
Adjust the position with the arrow keys so that the corona-shaped red circular orbit is as homogeneously distributed as possible around the blind spot.
Adjust the trajectory radius by B key or H key.
This is a method capable of accurately detecting the blind spot diameter.
  As a result of the inspection, the left and right blind spot states can be displayed on the display side by side with the fixation target centered side by side.
The left-right difference in the position of the blind spot and the left-right difference in the blind spot diameter scale are intuitively displayed on the display (see FIG. 27).
When changing the size of the target for carrying out the circular orbit (see 30, 40 in FIG. 27), the influence of the size of the target on the detection blind spot area increase / decrease can be seen.
  The programs A and B of the present invention can calculate the diameter ratio of the left and right blind spot approximate contours (see FIG. 27).
The difference in the size of the left and right blind spots can be evaluated numerically (see 2 in FIG. 27).
For example, if the right eye blind spot is larger, the program of the present invention calculates the right blind spot diameter / left blind spot diameter.
  If the result is 1.06, the diameter of the right blind spot is 1.06 times the diameter of the left blind spot.
The right blind spot is 6% larger than the left blind spot.
The left-right difference in blind spot diameter can be expressed intuitively and intelligibly (see 2 in FIG. 27).
In the left and right blind spot comparison, the relative degree of glaucoma is grasped.
The left / right blind spot comparison represents the effects of intraocular pressure, axial length, stress on the retina, and adverse effects on visual function (see 2 in FIG. 27).
  In the present invention program A, program B, program C, and program D, the blind spot area contour is approximated by a circular orbit.
This is to make it possible to detect the blind spot diameter at a high speed.
  When the blind spot is approximated from the inside by a green circular orbit, the blind spot minimum area when a blind spot that is not completely circular is approximated from the inside by a circular orbit is extracted.
  When a blind spot is approximated from the outside by a red circular orbit, the maximum blind spot area is extracted when a blind spot that is not completely circular is approximated from the outside by a circular orbit.
  In the program B of the present invention, the detected inner green circle orbit and outer red circle orbit can be collectively displayed on the display as a result of such a blind spot inspection (see FIG. 28).
  The deviation of the bi-circular orbit represents the degree of deviation of the blind spot area from the circular orbit.
  To inspect the degree of deviation of the blind spot area from the circular orbit, first move the inner green circle orbit completely within the blind spot area. To be precise, the corona green distribution seen around the blind spot is adjusted with the arrow key, B key or H key so as to make the circumference uniform.
  Thereafter, the subject adjusts the trajectory radius using the B key or the H key so that the red circular trajectory is completely outside the blind spot area.
  However, there is distortion in visual recognition around the blind spot.
The phenomenon may represent distortion such as unevenness of the retina.
May represent glaucomatous characteristics.
  Program B for functioning as a display showing an area with distortion around the blind spot, which represents a range with distortion around the blind spot.
  To do so, first move the inner green circle orbit so that it is completely within the blind spot area.
To be precise, the position is adjusted while making the corona green distribution visible around the blind spot uniform.
  Thereafter, the subject adjusts the trajectory radius so that the red circular trajectory is completely outside the blind spot area.
However, the trajectory radius is increased by the H key to such an extent that the subject can recognize the red circular trajectory as a complete circular trajectory (see 36 in FIG. 28).
The subject can recognize a complete circular orbit because the visual recognition is distorted around the blind spot, so the red circle orbit is not recognized as a circular orbit immediately around the blind spot, and the trajectory is distorted or a trajectory defect occurs. This is because there is a region (see 62 in FIG. 28).
  When the visual field inspection is continued with the fixation target gaze, the position of the blind spot always moves little by little (see 5 in FIG. 26).
The size of the blind spot always changes little by little (see 15 in FIG. 26).
A program D for functioning as the present invention capable of displaying the movement and change state on the display.
In order to reflect the temporal movement of the blind spot position and the temporal change of the blind spot diameter scale on the display, the inspection speed is increased. Perform blind spot detection to some extent.
However, it is accurate because it uses two inner and outer circular orbits.
Easily detect blind spot position diameter.
  For example, when detecting the degree of blind spot change with respect to the visual field inspection time of the right eye.
The subject blocks the left eye field and stares at the central fixation target with the right eye.
Move to the subject's blind spot area by moving the green mark in the center fixation target to the right side with the arrow keys.
Press enter when the green * mark is not visible in the field of view. The green * mark disappears.
The fixation target continues to be displayed (see 6 in FIG. 29).
The subject continues to stare at the fixation target.
A purple * mark target (see 25 in FIG. 29), and two inner and outer circular orbit targets (see 14, 22 in FIG. 29) appear.
  Program C for functioning as the present invention when it is desired to accurately detect blind spot position fluctuations.
A purple mark * (see 25 in FIG. 29) is set so as to appear in the vicinity of the fixation target (see 6 in FIG. 29).
The subject must move the purple mark (see 25 in FIG. 29) from the vicinity of the fixation target (see 6 in FIG. 29) to the blind spot at every examination.
In this method, the center position of the blind spot detected by the subject is not affected by the test result regarding the blind spot position so far.
  However, when paying attention to the time change of the blind spot, the present invention program D is used.
From the viewpoint of reducing the examination time, the purple * mark (see 25 in FIG. 29) appears approximately at the position of the blind spot detected by the examination results so far, and is a method of reducing the position adjustment time by the subject.
  However, the inner and outer circular orbits (see 14 and 22 in FIG. 29) are displayed by increasing the moving radius to some extent at each inspection.
Since the radius is increased to such an extent that the subject can recognize the inner green circle or outer red circle, the inner green circle orbit (see 22 in FIG. 29) is completely within the blind spot area every time the examination is performed. Adjust the trajectory radius so that
When the trajectory radius is reduced by the B key, the radius is reduced and the position is adjusted while adjusting the position so that the corona green distribution is uniform around the blind spot, and attention is paid to the corona balance of the green distribution around the blind spot.
  For example, when the blind spot tends to move to the ear side with the examination time, when the trajectory radius is reduced by the B key, the green target corona shape on the circumference of the blind spot immediately before the green circle orbit becomes invisible. The distribution is recognized with bias toward the nose.
In that case, the green circle orbit is moved to the ear side by an arrow key or the like.
Average the green corona balance around the blind spot.
In this method, the green corona distribution recognized by the subject around the blind spot is adjusted so that it is as homogeneous as possible around the circumference.
A system that adjusts to create a corona with a green orbit that is homogeneous around the circumference of the blind spot.
This is a method of adjusting the trajectory radius so that the inner green circle orbit becomes invisible due to the blind spot, but the outer red circle orbit appears homogeneous around the blind spot.
Use the B key or H key to determine the blind spot position and blind spot radius.
Press enter.
  By repeating the same examination, the program D of the present invention can show the time transition of the blind spot position and blind spot diameter on the display (see 5 and 15 in FIG. 26).
Since the results of repeated inspections of the blind spot position and blind spot diameter in the visual field are overwritten on the display, the temporal transition state of the blind spot position is well understood (see 5 in FIG. 26).
The display color of the blind spot outline is changed with time (refer to 5 and 15 in FIG. 26).
  The blind spot position moves, for example, in the horizontal ear direction in proportion to the length of the examination time (refer to 5 and 15 in FIG. 26).
However, fluctuations may occur in the moving direction (see 5, 15 in FIG. 26).
The detected blind spot diameter may also fluctuate depending on the length of the examination time (refer to 5 and 15 in FIG. 26).
  However, in the overwriting, the previous blind spot position motion described in duplicate on the display cannot be grasped.
In order to improve the state where the fluctuation is not reflected in the display when the movement of the blind spot position fluctuates not only in one direction but also in the reverse direction, the change of the blind spot position and the blind spot radius with time is displayed in an intuitive graph.
  It is the graph display which makes time a coordinate axis.
The information regarding the blind spot position and blind spot radius is a graph that collectively displays in the direction perpendicular to the time coordinate axis (see 15 in FIG. 26).
It has been observed that the detected blind spot position is horizontally moved sequentially in proportion to the time (see FIGS. 5 and 15).
However, there are cases where the blind spot position does not move in proportion to time and is not flexible.
The blind spot diameter may increase with time (see 5, 15 in FIG. 26).
  The phenomena displayed on the display by the program D of the present invention, such as the degree of flexibility in moving the blind spot position with respect to time and the degree of change in the size of the blind spot diameter (see FIGS. 5 and 15 in FIG. 26), May represent a feature.
  The present invention program A, program B, program C, and program D can select the detection blind spot diameter error degree by changing the radial distance difference of the inner and outer circular orbits.
The target can be selected to an appropriate size for the program.
  73. A computer,
  The program for functioning as this invention which enables a test subject to select a visual field test | inspection range, looking at a visual field defect | deletion and a visual function fall state on a display.
  The program of the present invention is a method in which the display is alternated in two colors at an appropriate time interval in order to allow the subject to recognize his / her visual field deficit and visual function deterioration state.
  The method of the present invention program is particularly useful when the subject has glaucoma characteristics, when the retina has a reduced cone cell density, or when the blind spot diameter is increased due to intense myopia.
It is effective.
  In order for a subject in such a state to recognize a visual field defect state, red-orange and black alternate display is particularly effective.
  By the method of the present invention program, the subject can recognize the presence / absence of the visual visual function deterioration part and the visual field defect part from the display color defect, such as the shape and the positional relationship with the fixed viewpoint.
  When two-color display of the display color is performed alternately at an appropriate time interval, the visual function deterioration area such as the dark spot, the blind spot diameter enlarged portion, etc. cannot follow the display color change in time, and remains as an afterimage. A subject, such as a dark spot or a blind spot diameter enlarged portion, is recognized as a color defect on the display.
  Using red-orange-black color, which is difficult to follow visually, the subject can see the shape of the visual function-decreasing region such as the blind spot blind spot on the display including the peripheral visual field in considerable detail.
  The field of interest becomes clear and the field of view visual function scan inspection range can be selected very easily.
  The program of the present invention can move the fixation target, and the subject can move the visual field of interest near the center of the display. This is useful when the field of interest is recognized at the edge of the display.
  In order to record the visual field state of the subject visually recognized as a color defect on the display to the computer in a reproducible manner with high resolution, the subject performs visual visual function scanning using a static dynamic diopter. Use.
  In the program of the present invention, the subject sees his visual field deficit state on the display.
Since the fixation target can be moved and the visual field to be inspected can be moved to the center of the display, it is useful when the inspection object does not fully enter the display, such as a blind-eared part.
  Since the subject can limit the examination range while viewing his / her visual field defect state on the display, the resolution of visual field visual function scanning can be increased while shortening the examination time.
  Therefore, the shape of the dark spot blind spot, the shape of the connecting part of the dark spot blind spot, etc. are reproduced and recorded in great detail on the display.
  The visual field function scan uses a dynamic target to speed up the visual field inspection.
The target moving speed can be selected from the viewpoint of reducing the inspection time, such as decreasing the target moving speed when inspecting a narrow range in detail, or increasing the target moving speed when inspecting a wide range.
  In the program of the present invention, a high-resolution visual field visual function scan result diagram obtained in a short time by limiting the examination range can be used in an accumulated manner.
  It is possible to synthesize and display on the display a diagram of the results of short-time inspections performed in a plurality of times.
Short-term visual field inspection has less burden on the subject.
  The subject can adjust the distance from the display to the subject by matching the composite view of the results up to the previous examination displayed on the display with the size and positional relationship of the blind spot visually recognized by the subject. It is possible and may reduce the composite deviation from subsequent inspection of the visual field functional scan diagram.
  While performing visual visual function scanning without interruption in the horizontal direction, the static visual target is detected as long as the subject's ability to react to the visual target recognition is established in order to detect the spatial separation ability equivalent to character recognition and reflect it in the inspection result. The waiting time is set until becomes a static dynamic target.

Functional scan program.   The spatial separation ability of the central visual acuity is high (FIG. 1, central visual acuity 14), and the spatial separation ability of the central external visual acuity is low (see central external vision 6 of FIG. 1). As the visual field is farther from the center, the number of pyramidal cells decreases, so the spatial separation ability decreases. In areas with low spatial resolution (see FIG. 1, external visual acuity 6), the dynamic visual target speeds up the examination. However, since the dynamic visual target moves at a constant speed in the horizontal direction, the inspection accuracy is uniform. Central vision and non-central vision functions can be inspected uniformly. It is possible to perform a test that is not affected by the judgment of the writer and the preconception about the visual field of the subject. Information on the degree of spatial resolution detected by the dynamic visual target is statically obtained by alternately linking the dynamic visual target and the static visual target without spatially separating them (see FIGS. 5 and 7).

When the subject can recognize the movement of the dynamic visual target A in the visual field, he or she presses the button or the space key. The dynamic visual target A becomes a static visual target A dash at that position (see 22 in FIG. 5). With the static target A dash continuously displayed, the dynamic target B having the same shape and size starts to move in the right horizontal direction at the same speed from the position of the static target A dash (FIG. 4). 12).

The full-field retinal function scanning program according to claim 1, wherein the full-field retinal function scanning program can be scanned repeatedly.   The state of vision loss is difficult to explain to others, but it can be intuitively explained by the present invention.   Since the central part of the visual field and the macular part have high spatial resolution, the distance between the static visual target and the dynamic visual target when the button or the space key is pressed becomes short. In the fovea portion, the distance between the static visual target and the dynamic visual target is the shortest (see 5 in FIG. 1). On the display, the degree of the distance between the static visual target and the dynamic visual target is converted into a color shading and displayed as a shading two-dimensional scan diagram. Scaled display such as bright color when the distance between the two points of static and dynamic targets is long, dark color when the distance between the two points of static and dynamic targets is short I do. In the present invention, the full-field retinal function scanning program according to claim 1, which can be measured with an accuracy of about 10 minutes or less, such as a full-field effective photoreceptor density in one eye, but has a shorter examination time than the examination accuracy.   Since humans gain sight through the optic nerve and brain, the ophthalmoscope does not know the state of higher visual function than the retina. If you are not a subject, you will not know the state of the dark spot. Even the test subject cannot recognize the shape and size of the dark spot around the visual field other than the fixed viewpoint and the central part of the visual field (see the part 4 where the dark spot and the blind spot are connected in FIG. 1). The present invention makes it possible to faithfully reproduce the dark spot and blind spot shapes that can be transmitted from the retinal photoreceptor cells to the visual cortex on the display. The retina in the eye, the area where the optic nerve does not function effectively (see dark spot 1 in FIG. 1), the area where visual function is reduced (see area 15 where the pyramidal cells or optic nerve axons in FIG. 1 are slightly impaired). The full-field retinal function scanning program according to claim 1, which can be clearly reproduced on a display like a map.   Since the dynamic target is moved at a constant speed in the horizontal direction, it is possible to perform a test that is not affected by the judgment of the dark spot area of the subject and prejudice, and the objectivity of the test result recorder is maintained. It is. In the conventional dynamic perimeter, the dynamic target moves in a random direction, and the spatial resolution does not appear in the examination result. By moving in the horizontal direction, information on the horizontal spatial resolution was accumulated in the inspection results, enabling two-dimensional scan display.   Intuitively understand the severity of the dark spot area relative to the fixation point and the macular area. As a result of the measurement, the difference in resolution of the visual field was expressed in detail as a two-dimensional scan, and the shape of the visual field defect portion (see 1 in FIG. 1) and the shape of the blind spot were displayed on the computer screen. The blind spot diameter enlarged state (see 2 in FIG. 1) due to the optic nerve depression or the like can be displayed. In addition to visual field defects and dark spots, areas that have slightly damaged pyramidal cells, reduced cone density, or reduced cone function can be displayed on the display as a two-dimensional scan on a gray scale. (See 15 in FIG. 1.) The full-field retinal function scanning program according to claim 1.   Since the present invention can detect a spatial resolution of about 10 minutes or less, it cannot be found in a conventional perimeter having a defect that a field defect within a few degrees cannot be detected such that a connection portion from a dark spot to a blind spot becomes gradually thinner. A glaucoma characteristic of a dark spot can be detected (see 4 in FIG. 1). The full-field retinal function scanning program according to claim 1, which is capable of detecting and displaying a relationship between a Bjerrum region dark spot and a blind spot such as a glaucomatous visual field defect and a horseshoe-shaped dark spot.   The full-field retinal function scanning program according to claim 1, wherein the shape of a visual field defect field such as laser retinal property in a field far from the fovea can be detected and displayed at high speed.   By using two points of a static visual target and a dynamic visual target alternately and continuously, recognition of the dynamic visual target by the subject becomes a central work for the off-center visual field, and the examination time is shortened. On the other hand, for the macular region, which is an important part in vision, static target recognition becomes a central task, and the degree of visual function can be inspected in detail slowly. The full-field retinal function scanning program according to claim 1, wherein a portion having low spatial resolution can be inspected at high speed by high-speed processing, and a portion having high spatial resolution can be inspected by low-speed processing.   Inspection can be speeded up by using dynamic targets for static targets. Humans can respond quickly to moving objects. Dynamic visual targets are less susceptible to visual familiar afterimages than static visual targets, and the examination time can be shortened by reducing the subject's confirmation judgment time for the appearance of the visual target. Due to the high sensitivity of the dynamic target to the human static target, the subject will not respond to the reappearance of the dynamic target even after a certain amount of areas, such as dark spots, where the spatial separation ability is low. High speed response is possible (see 16 in FIG. 1). The full-field retinal function scanning program according to claim 1, wherein the horizontal movement of the dynamic visual target having a certain distance, the speed thereof, etc. significantly reduce the monotony of the conventional perimeter.   The full-field retinal function scanning program according to claim 1, wherein the fixation point fixation target increases the fixation point gaze degree of the subject by performing high-speed two-color alternate blinking (see 25 in Fig. 3). With a non-flashing fixation target such as a conventional perimeter, it is difficult to stare due to a visual afterimage.   Since the subject performs fast flashing fixation point fixation target fixation, there is a case where the dynamic target cannot be recognized even if it reaches the right end of the display (see 27 in FIG. 6). In such a case, the dynamic optotype reaches the right edge of the display, the inspection of that line is in the end state, and a mark indicating that it is waiting for the inspection of the next lower line (see 26 in FIG. 6). .)

Alternatively, the full-field retinal function scanning program according to claim 1, wherein the examination can be restarted after a short break.   The full-field retinal function scanning program according to claim 1, wherein the visual function level of the visual function-reduced area is also displayed in a scannable manner intuitively.   After the field-of-view inspection is completed, the above mark is displayed, and each time the button or space key is pressed to start the next-line inspection, the result of the visual field function two-dimensional scan up to that point However, only the inspected area from the bottom line is displayed instantaneously. The subject can hardly recognize what the scan results are due to fixation target gaze, but can recognize a very bright display near the dark spot and blind spot area, so It has an effect of greatly reducing, and can prevent a decrease in visibility due to a familiar afterimage (see FIG. 2). By bringing about a change, the subject's concentration can be maintained. The subject can roughly recognize the progress of the examination by peripheral vision. It is also possible to adjust so that the scan results are not sequentially displayed on the display during the inspection by the program. The program can be adjusted in various ways such as the size of the target. The target moving speed and moving direction can be adjusted in various ways by the program, so the inspection time can be adjusted. The full-field retinal function scanning program according to claim 1, wherein display programs, shades and color tones of full-field spatial resolution scanning can be variously adjusted by the program.   Since the inspection method of the present invention is simple, it is possible to easily experience visual field inspection and observation of blind spots at home. By visualizing the visual field state of the subject at home, explanation of the visual field state of the subject can be facilitated. 2. The full-field retinal function scanning program according to claim 1, wherein since the inspection output result is beautiful, the visual field inspection is performed for a certain period of time, and the result can be relaxed by looking at the output.   A program that expresses a density difference by a vertical sum of a plurality of linear functions, which is difficult to show in a gray scale scan and is a power function variation (see FIGS. 8 and 9).   Program A that makes it possible to perform a very detailed visual function test by actively selecting the inspection range in advance, and to display the result clearly and clearly on the display. The inspection range is a full-field retinal function scan filed on June 18, 2007, or a portion in which a visual visual function failure is detected in the high-speed inspection method according to claim 27, or a range (blind spot etc.) to be observed in particular. You can choose. A program that can obtain inspection results with very detailed spatial separation in a short time by the method of performing visual field inspection with limited range.   24. The program A according to claim 23, wherein the shape of the connection area from the dark spot to the blind spot, which is said to be characteristic of glaucoma and macular neovascularization, which cannot be detected by a conventional perimeter, can be shown in detail and intuitively on a display. The degree of enlargement of the blind spot diameter can also be illustrated in detail. A visual function-decreasing area can also be illustrated.   If the inspection range is limited, such as the shape of the dark spot, the shape of the blind spot, the shape around the fixed point of the dark spot, and the shape of how the dark spot blind spot is connected, these shapes can be shown in detail on the display at high speed. Item 24. Program A according to Item 23.   24. The program A according to claim 23, which enables an examination that is not affected by the judgment and preconception of the recording of the subject's dark spot area, and maintains objectivity for the recording of the examination result diagram.   In the conventional perimeter, the examination space separation ability is rough, the shape of the dark spot blind spot of the examination result is very rough and difficult to understand, and the examination time is very long. The present invention makes it possible to accurately display the shape of the dark spot blind spot of the subject on the display, and to adjust the movement of the target passively and passively, which has the feature that the examination time can be greatly shortened because of the contour extraction method. A visual field inspection method that enables high-speed contour extraction of the visual field function state and display on the display, and program B therefor.   A visual field inspection method used in the program B according to claim 27 (refer to FIG. 10 for a visual field inspection result). In visual field inspections in which the static target is moved sequentially in the horizontal right direction every time it is confirmed that the subject has recognized, the subject will have a similar button press response in the field where the visual field is not impaired or in the dark spot blind spot field. Will continue. However, since the subject learns and memorizes the same button press response and uses that memory in the subsequent response process, even if the subject recognizes that the target is not visible, the person who uses the memory rather than recognition However, it is easy to make a wrong button response as if the target was visible. Even if the subject carefully presses the button so as not to make an incorrect response regarding the target recognition, immediately after making the same button response several times, the tendency to make an incorrect response is very high, In the case of a rough visual field inspection, the error due to the mistake is large. In addition, subject's carefulness to avoid false button responses leads to an increase in examination time. Therefore, in the visual field inspection method using the program B of the present invention, in order to solve such a problem, unless the change in the visual sensitivity in the visual field is recognized, the subject keeps pressing the button to set the visual target in advance in the computer. , Move the button dynamically only when it recognizes the change in visibility, make the dynamic target a static target, and the subject actively moves the target in the opposite direction. A method is adopted in which the position is adjusted by moving it in the forward direction and the visibility change point is determined by pressing the space key. In areas where the visibility does not change, the subject does not respond by pressing the button every time it confirms that there is no change, but moves the dynamic target to the inside of the dark spot or blind spot area to some extent. This is a method for speeding up the visual field inspection by continuing to press the target right direction movement button. Since some position determination error is allowed at that time, the moving speed of the dynamic visual target can be set to be somewhat high. When the subject recognizes that the dynamic target has entered the dark spot or the blind spot but the dynamic target is still visible, the subject releases the target rightward movement button once. The dynamic target becomes a static target. Requesting the subject to respond to the dark spot or blind spot at the moment when the visibility changes changes the response time to human stimuli, especially immediately after the same stimulus is repeated repeatedly. The response is quite unreasonable because the learning and memory effect of a response that has been repeated several times so far appears strongly and tends to be an incorrect response. However, it is easy for a subject to recognize immediately after an error response that an error response has been made to a different stimulus after the same stimulus repeated several times. After that, since the subject actively determines the position where the visibility changes due to the dark spot or blind spot area while moving the target slightly to the left and right and correcting it, the shape of the extracted contour is very It is accurate and faithfully reflects the visual function status, such as the subject's dark spot and blind spot. The test result is shown on the display and is intuitively easy to understand (see FIG. 10). Since the subject only needs to respond to only the visibility change contour, by adjusting the size of the visual target and the moving speed of the visual target, a high-speed inspection with an inspection time of 5 minutes or less for a one-side visual field is possible. . Although it is a high-speed inspection that is impossible to achieve with a conventional perimeter, if the inspection result is only a contour, a diagram of a full-field retinal function scan visual field inspection result submitted on June 18, 2007 (FIG. 11, − 1), and an accuracy equivalent to that of the very detailed visual field inspection result (see FIG. 9) according to claim 23 for actively setting the inspection range. In the method of the present invention, in order to speed up the entire visual field inspection, the dynamic target is used at a moving speed set in the computer in advance, and when the one-line inspection in the horizontal right direction is completed, the next line inspection is started from the left end. The subject performs passively under control, but in order to accurately extract the contours of the visual function changes such as dark spots and blind spots, the dynamic visual target is changed to a static visual target around the visual sensitivity change part, and the visual sensitivity changes This is a method in which the subject actively adjusts the target position in order to accurately extract the contour. Because it is a program, it is possible to refine the inspection result diagram or increase the inspection speed by adjusting the size and moving speed of the computer-controlled dynamic target.   By enlarging the target or inputting the target into the computer, the geometric shape of the target passing dynamically can be observed around the blind spot. In addition, since the target can be input by a computer, when a character or the like is used as a target, the degree of character recognition in the visual field can be observed. 28. The program B according to claim 27, wherein various observations relating to the visual field visual function can be performed, the observation result and the contour relating to the visibility change position can be extracted at high speed and can be intuitively illustrated on a display.   The visual field inspection method according to the program B according to claim 27 enables an inspection that is not influenced by the judgment of the writer on the dark spot area of the subject and the preconception, and the objectivity to the writer of the inspection result diagram is maintained. .   The subject aims at speeding up the visual field inspection by adopting a method in which the subject is required to respond only to the dynamic visual target moving in the horizontal right direction when the change in the visibility is recognized. It is easy for the subject to recognize the appearance of discontinuous positions of the visibility on the dynamic target moving in the horizontal right direction. The visual field inspection method used when using the program B according to claim 27, which is a method using a characteristic that sensitivity to a human discontinuity start point is sensitive. Unless the change is recognized in the visibility, the subject keeps pressing the right direction movement button → and does not respond one by one, so the examination time can be shortened. The subject can easily recognize that he has gone too far to the right of the visibility change position. After such recognition, the subject can accurately determine the discontinuity of the visibility while actively moving the visual target around the discontinuity of the visibility with the left movement button ← or the right movement button → Press to record the position. In the visual field inspection method using the program B according to claim 27, the subject who is generated because the subject's target recognition confirmation leap time is converted into the active position adjustment time by the subject, and the target recognition is accurately performed. As a result, the visual field inspection process is speeded up, and at the same time, the accuracy of contour extraction is achieved. Since it is a method that can be inspected while adjusting the position by recognizing that the target has moved too far in the right direction, etc., the temporal response during contour extraction by the subject The recording position error due to delay or the like can be reduced to zero.
The response method of the subject with respect to the visual field inspection according to claim 32 with respect to the program B according to claim 27 is not limited to the visual field, and can be applied to general searches for extracting features of interest from a wide range at high speed.   The visual field inspection result using the visual field inspection method according to claim 32 in the program B according to claim 27 is easy to understand and interesting because it is a feature contour extraction type (see FIG. 10). By appropriately setting the size of the target, the moving speed, etc., it is possible to realize a one-eye full-field inspection time of 5 minutes or less.   The result of the visual field inspection is shown in detail on the display by the program of claims 23 and 27, and the shape of the visual field defect portion (see 1 in FIG. 9 and 1 in FIG. 10) and the shape of the blind spot (2 in FIG. 9). , See 2 in FIG. 10) is displayed on the computer screen. The degree of seriousness of the dark spot area relative to the fixation point and the macular portion can be intuitively understood (see 14 in FIG. 9 and 14 in FIG. 10). It is possible to display in detail such as the blind spot diameter enlarged state due to optic nerve depression.   The visual field defect state is difficult to explain to others, but by using the program A according to claim 23, the program B according to claim 27, and the visual field inspection method according to claim 32, it is intuitive in a very short time. (See FIGS. 9 and 10).   According to the present invention, by virtue of the method of actively selecting the area to be inspected, the program A according to claim 23, in which the visual field function state is shown in detail on the display, can detect a very fine spatial resolution, so that from the dark spot to the blind spot. It is possible to detect glaucoma characteristics (see 4 in FIG. 9) of about several minutes, which cannot be detected with conventional perimeter accuracy, such that the connection portion of the first and second connections becomes thinner. It is possible to detect and display the relationship between Bjerrum area dark spots and blind spots such as glaucomatous visual field defects and horseshoe-shaped dark spots in great detail.   The visual field inspection result diagram by the program A according to the present invention and claim 23 shows in detail the bending state of the dark spot area (see 1 in FIG. 9), which is very helpful when estimating the origin of the dark spot. become. The result of the inspection of the conventional basic perimeter does not show the degree of bending of the dark spot area.   According to the present invention, the visual field functional state is extracted at high speed by passively moving and adjusting the visual target, and the visual field inspection method according to claim 32 and the visual field inspection method according to claim 32 are illustrated on a display. By appropriately setting the size and moving speed, the contour of the glaucoma characteristic of about several minutes that cannot be detected with conventional perimeter accuracy, where the connection from the dark spot to the blind spot becomes gradually thinner Can be detected (see 4 in FIG. 10). It enables high-speed inspections such as the relationship between dark spots and blind spots in the Bjerrum area, such as glaucomatous visual field defects and horseshoe-shaped dark spots, and detailed contour display at a very high speed.   The present invention, the program B according to claim 27 and the visual field inspection method according to claim 32 make it possible to extract in detail the contour of the bending state of the dark spot area, and to display it on the display (see 1 in FIG. 10). .) It is very helpful when estimating the origin of dark spots. The result of the inspection of the conventional basic perimeter does not show the degree of bending of the dark spot area.   The program A according to claim 23, wherein the visual field function state is illustrated in a display in a very detailed manner by a method of actively selecting a field to be inspected according to the present invention, and a visual field defect such as laser retinal property in a field far from the fovea. It can detect and display a very detailed shape of the area. The present invention, high-speed contour extraction of visual field functional state by passively moving and adjusting the target,
27. The program B according to claim 27 and the visual field inspection method according to claim 32, which are shown on the display, detect the contour of a field defect field shape such as a laser retinal region in a field far from the fovea at a very high speed. Make it possible to do.   The program A according to claim 23 can shorten the inspection time by actively selecting the inspection range. On the other hand, in the high-speed contour extraction type program B according to claim 27 and the visual field inspection method according to claim 32, a region where the retinal visual function is impaired or the feature to be observed is not discontinuous is passively used by using a high-speed dynamic visual target. A high-speed visual field inspection is possible, a region where the retinal visual function is impaired, or a feature to be observed is discontinuous, a dynamic visual target can be converted into a static visual target, and an active visual field inspection can be performed at a low speed. Since the subject responds only to the contour portion, the examination time is greatly shortened.   With program B described in claim 27, you can observe how the geometric shape is strangely distorted around the blind spot when the geometric symbol is a dynamic target. You can observe the appearance of a geometrical figure as if it was sucked into a blind spot with central visual acuity. If you move the dynamic target horizontally above the fixation target, you can see how the dynamic target moves in a spiral, and know that two photoreceptor clusters are converged in one ganglion. can do. If the character is a dynamic target, you can know the degree of character recognition in the macula.   A method for extracting features of interest from a wide-range search object at high speed, or a general method for reducing the driving force of the work when it is necessary to sequentially understand or recognize a wide-range object. A method in which the search speed, understanding, or recognition speed is changed actively depending on the search or understanding target, and the search error, understanding, or recognition error can be greatly reduced. If it is a search, an object that diverges from interest and an object that can be inferred from tradition perform considerably high-speed processing. If it is understanding, understanding of the object that can be inferred from the memory is performed at a considerably high speed. However, if it is a search, it will be a very slow process for an object of interest, a target that deviates from tradition, and if it is an understanding, an object that cannot be inferred from memory will take a considerable amount of time by taking a sufficient amount of time. , A way to try to achieve understanding or recognition. In understanding and recognizing, humans cannot understand the memory collation search time for understanding and recognizing flexibly and actively according to the object. Mistakes in understanding or recognition because it does not take the necessary reaction time. In understanding the object, the part inferred from the memory can be understood at high speed, but the part that cannot be inferred from the memory cannot be understood at all, but the superficial processing is continued, the uncertainty of definition accumulates in the processing, and the work is promoted. Derived from a phenomenon in which power is often reduced.   The program A according to claim 23 of the present invention, the program B according to claim 27 and the visual field inspection method according to claim 32 have a simple inspection method, so that the user can easily experience visual field inspection, observation of blind spots, etc. even at home. Can do. By visualizing the visual field state of the subject at home, explanation of the visual field state of the subject can be facilitated. In the program B according to claim 27, various features of the retinal vision function and the blind spot can be observed. Further, in both cases of program A and program B, since the inspection output result is beautiful, it is possible to relax by performing a visual field inspection for a certain time and looking at the output. 48. A full-field retinal visual function scan according to claim 47, which enables a computer to immediately become a perimeter, a retinal visual function test meter, and enables a frequency distribution graph display for visual field space separation ability. In the case of full-field measurement, the horizontal visual field inspection was speeded up precisely by using two points of the dynamic visual target and the static visual target alternately. Scan the test results sequentially from the bottom row by moving the fixation target in the vertical downward direction with the vertical position of the dynamic and static targets moving in the horizontal direction fixed at the center of the display. Generate a diagram. (See FIG. 16). Since the inspection method uses two visual targets alternately, a full-field retinal function scan, program 1 that dynamically increases the inspection speed in the external vision while statically increases the inspection details in the macula. . The spatial resolution of central vision is high, and the spatial resolution of external vision is low. As the visual field is farther from the center, the number of pyramidal cells decreases, so the spatial separation ability decreases. In areas with low spatial resolution, dynamic visual targets speed inspection. However, since the dynamic visual target moves at a constant speed in the horizontal direction, the inspection accuracy is uniform. Central vision and non-central vision functions can be inspected uniformly. It is possible to perform a test that is not affected by the judgment of the writer and the preconception about the visual field of the subject. Accumulating information on the degree of spatial separation detected by dynamic targets in the test record as static targets by continuously linking dynamic targets and static targets without any spatial separation be able to. The test result is a retinal function two-dimensional scan. (See FIG. 16 etc.). After executing the visual field retinal function scanning and program 1, the frequency distribution with the spatial resolution as a class can be displayed on the display as a columnar graph (see FIG. 18 and the like). The frequency distribution graph is displayed in the order of the spatial resolution.
In the case of the program 1 of the present invention.
The spatial resolution capability distribution graph is a visual function distribution (see FIG. 16, etc.) that is spatially arranged and expressed in the two-dimensional direction in the full-field retinal function scan result diagram, and the spatial resolution capability in the one-dimensional direction. (See FIG. 18 and the like). By observing the same distribution from two different viewpoints, it was possible to infer whether the distribution generation process of one (for example, full-field retinal function scan result diagram) was plausible and appropriate.
From the spatial separation ability frequency distribution graph, it can be seen that the central visual acuity is restricted by the visual information processing capacity (see 1 in FIG. 18), and the external visual acuity is restricted by the retinal area (see 2 in FIG. 18). . Due to the limitation of visual information processing capacity and the optimized balance of maximal spatial resolution with respect to the retina area, both sides of the frequency distribution graph have an increasing exponential function on the left side and a decreasing exponential characteristic on the right side. The resolution frequency distribution graph shows a single peak shape. In particular, in the central visual acuity, the frequency of a class having a large spatial separation power is remarkably reduced, and the frequency is expressed in a columnar graph in a state where the visual information processing capacity is strongly restricted. If the examination-side visual field frequency distribution graph is displayed on the opposite side frequency distribution graph as a background, it is possible to infer a spatial resolution class in which the visual function in the examination-side visual field is degraded or the visual field is missing. . A spatial resolution class that constitutes a visual field defect area such as a dark spot appears as a frequency in a class having a low spatial resolution (see 5 in FIG. 18). In addition, the spatial separation power distribution graph of the contralateral visual field may provide a contrasting background distribution for examining the visual field condition for the examination visual field (see FIG. 14). In the case of the program 1 of the present invention.
The full-field retinal function scan according to claim 47, wherein the inspection result becomes a beautiful scan diagram of sequential two-dimensional gray scale display, which is displayed on the display during the inspection, and can display a spatial separation power distribution graph that reduces the monotonicity of the visual field inspection. Program 1. In the case of the program 1 of the present invention.
Two-point target system for full-field inspection. Block the eyes that will not be inspected. First, the subject gazes at the fast flashing fixation target on the display with the eye performing the visual field inspection. The dynamic visual target A appears while moving in the horizontal right direction from the central portion with respect to the vertical direction at the left end of the display. When the subject can recognize the movement of the dynamic visual target A in the visual field, the button is pressed. The dynamic target A becomes a static target A dash at that position. With the static target A dash being displayed, the dynamic target B having the same shape and size starts to move in the right horizontal direction at the same speed from the position of the static target A dash. Press the button or space key when the subject recognizes the two points of the static target A dash and dynamic target B or the movement of the dynamic target B in the field of view. . The static target A dash disappears from the display, and the dynamic target B becomes the static target B dash at the position where the button is pressed. With the static target B dash displayed, the dynamic target C appears from the position of the static target B dash and starts moving in the horizontal direction at the same speed to the right. When the appearance of the dynamic visual target C with respect to the static visual target B dash is recognized by the subject's spatial separation ability or when the movement of the dynamic visual target C is recognized in the visual field, the button and the space key are pressed.
The visual function of the retina can be scanned by repeating similar processing. The dynamic visual target moves to the right end, the visual field inspection of that row is completed, and when the button or space key is pressed, the dynamic visual target appears from the left end of the same stage, but the fixation target is one level lower The field of view scan continues in a moving manner. The entire field of view of one eye can be scanned by repetition.
Since the central part of the visual field and the macular part have high spatial resolution, the distance between the static visual target and the dynamic visual target when the button or the space key is pressed becomes short. In the central foveal portion, the distance between the static visual target and the dynamic visual target is the shortest. On the display, the degree of the distance between the static visual target and the dynamic visual target is converted into a color shading and displayed as a shading two-dimensional scan diagram. When the distance between the static target and the dynamic target is long, the display is divided into bright colors, and when the distance between the static target and the dynamic target is short, the display is divided into dark colors. . According to the first aspect of the present invention, the program 1 can measure the entire field of view effective photoreceptor density of one eye with an accuracy of about 2 minutes or less, but the inspection time is short regardless of the high accuracy of the inspection.
Since humans obtain sight with the optic nerve and brain, the ophthalmoscope does not know the state of higher visual function than the retina. If you are not a subject, you will not know the state of the dark spot. The subject cannot recognize the fixed point, the shape and size of the dark spot around the visual field other than the central part of the visual field. The program 1 according to claim 47 of the present invention makes it possible to faithfully reproduce the dark spot blind spot shape that can be transmitted from the retinal photoreceptor cell to the visual cortex on the display. 48. The full-field retinal function scanning program 1 according to claim 47, wherein the retina in the eye, the area where the optic nerve does not function effectively, and the area where the visual function is reduced (see 25 in FIG. 16) can be reproduced and clearly displayed on a display like a map. .
Intuitively understand the severity of the dark spot area relative to the fixation point and the macular area. As a result of the measurement, the difference in resolution of the visual field was expressed in detail as a two-dimensional scan, and the shape of the visual field defect part and the shape of the blind spot were displayed on the computer screen. The state of enlarged blind spot diameter due to optic nerve depression or the like can be displayed. In addition to visual field defects and dark spots, areas that have slightly damaged pyramidal cells, reduced cone density, or reduced degree of cone function can be displayed on the display as a two-dimensional scan on a gray scale. (See 25 in FIG. 16, etc.) Full-field retinal function scan program 1 according to claim 47.
Since the present invention can detect a spatial resolution of about 2 minutes or less, it cannot be found in a conventional perimeter having the disadvantage that a field defect within several degrees cannot be detected such that the connection from the dark spot to the blind spot becomes gradually thinner. A glaucoma characteristic of a dark spot (see 26 in FIG. 16) can be detected. It is possible to detect and display the relationship between Bjerrum area dark spots and blind spots such as glaucomatous visual field defects and horseshoe-shaped dark spots.
48. The full-field retinal function scanning program 1 according to claim 47, wherein the shape of the visual field defect field such as laser retinal property in the field far from the fovea can be detected and displayed at high speed. In the case of the program 1 of the present invention.
By using two points of a static visual target and a dynamic visual target alternately and continuously, recognition of the dynamic visual target by the subject becomes a central work for the off-center visual field, and the examination time is shortened.
In general, visual recognition of external visual acuity, especially 2 visual recognition, is easy to use with static visual targets because the ease of recognition varies considerably depending on the length of time used to recognize them. It is difficult to perform an objective inspection.
However, in the case of the program 1 of the present invention.
By using a dynamic visual target with central visual acuity and a method that responds when the movement of the visual target is recognized in the field of view, fluctuations in the time required for visual recognition in the external visual acuity are detected. It is possible to considerably reduce the phenomenon that affects the degree of spatial separation.
In the case of the program 1 of the present invention.
In the macular region, which is an important part of vision, static target recognition is a central task, and the degree of visual function can be inspected in detail and slowly.
This is because the degree of target recognition of the central visual acuity is hardly affected by the length of time until recognition.
48. The full-field retinal function scanning program 1 according to claim 47, wherein a portion having a low spatial resolution can be inspected at high speed by high-speed processing, and a portion having a high spatial resolution can be inspected by low-speed processing.   Inspection can be speeded up by using dynamic targets for static targets. Humans can respond quickly to moving objects. Dynamic visual targets are less susceptible to visual familiar afterimages than static visual targets, and the examination time can be shortened by reducing the subject's confirmation judgment time for the appearance of the visual target. Due to the high sensitivity of the dynamic target to the human static target, the subject will not respond to the reappearance of the dynamic target even after a certain amount of areas, such as dark spots, where the spatial separation ability is low. High speed response is possible. 48. The full-field retinal function scan program 1 according to claim 47, wherein the horizontal movement of the dynamic visual target having a certain distance, the speed thereof, etc. considerably reduce the monotony of the conventional perimeter.   48. The full-field retinal function scanning program 1 according to claim 47, wherein the fixation point fixation target raises the fixation point gaze degree of the subject by performing high-speed two-color alternate blinking. With a non-flashing fixation target such as a conventional perimeter, precise gaze is difficult due to a visual afterimage.   Since the subject performs fast flashing fixation point fixation target gaze, there is a case where the dynamic target cannot be recognized even if it reaches the right end of the display. In such a case, the dynamic visual target reaches the right edge of the display, the inspection of that line is in the end state, and a mark indicating that it is waiting for the inspection of the next lower line is marked with a fast flashing fixation point part. Are displayed side by side on the fixation target. After the subject recognizes the mark on the fixation point fixation target portion, the test can be started on the next lower row by pressing the button or the space key. 48. The full-field retinal function scanning program 1 according to claim 47, wherein the examination can be started again after a short break.   48. The full-field retinal function scan program 1 according to claim 47, wherein the visual function level of the visual function-reduced area is also displayed in a scantably intuitive manner. After the field-of-view inspection is completed, the above mark is displayed, and each time the button or space key is pressed to start the next-line inspection, the result of the visual field function two-dimensional scan up to that point However, only the inspected area from the bottom line is displayed instantaneously. The subject can hardly recognize what the scan results are due to fixation target gaze, but it can recognize a bright display display in the vicinity of the dark spot and blind spot area, so that the subject is very tired It has the effect of decreasing, and can prevent a decrease in visibility due to a familiar afterimage. By bringing about a change, the subject's concentration can be maintained. The subject can roughly recognize the progress of the examination by peripheral vision.
It is also possible to adjust so that the scan results are not sequentially displayed on the display during the inspection by the program. The program can be adjusted in various ways such as the size of the target. The target moving speed and moving direction can be adjusted in various ways by the program, so the inspection time can be adjusted. 48. The full-field retinal function scan program 1 according to claim 47, wherein the program allows various adjustments such as display display, full-field spatial resolution scan density, and color tone.   Since the inspection method of the present invention is simple, it is possible to easily experience visual field inspection and observation of blind spots at home. By visualizing the visual field state of the subject at home, explanation of the visual field state of the subject can be facilitated. 48. The full-field retinal function scanning program 1 according to claim 47, wherein since the test output result is beautiful, the visual field test is performed for a certain period of time, and the result can be relaxed by looking at the output. By actively selecting the inspection range in advance, a very detailed visual visual function test can be performed, and the result can be clearly displayed on the display (see FIG. 20). The inspection range is a portion where the visual field visual function is detected in the program 1 according to claim 47 or the high-speed inspection method according to claim 65 (see program 3 ), or a range (blind spot etc.) to be observed in particular. You can choose. 61. The program 2 according to claim 60, wherein a test result having a very detailed spatial separation ability can be obtained in a short time by a method of performing visual field inspection with a limited range. (See 200 and 202 in FIG. 20). The shape of the connection area from the dark spot to the blind spot, which is said to be characteristic of glaucoma and macular neovascularization that cannot be detected by a conventional perimeter, can be shown in detail on the display (see 205 in FIG. 20). Program 2 described. The degree of enlargement of the blind spot diameter can also be illustrated in detail. A visual function lowered area or the like can also be illustrated (see 205 in FIG. 20).
61. The program 2 according to claim 60, which enables a test that is not affected by the judgment and preconception of a recording person on the dark spot area of the subject, and maintains objectivity for the recording person of the inspection result diagram.   In the conventional perimeter, the examination space separation ability is rough, the shape of the dark spot blind spot of the examination result is very rough and difficult to understand, and the examination time is very long. The present invention makes it possible to accurately display the shape of the dark spot blind spot of the subject on the display, and to adjust the movement of the target passively and passively, which has the feature that the examination time can be greatly shortened because of the contour extraction method. 66. A visual field inspection method that enables high-speed contour extraction of a visual field functional state state to be illustrated on a display, and a program 3 according to claim 65. For program 2.
The ratio of the visual field defect area to the visual field inspection area can be displayed in%. (See FIG. 20).
A conventional perimeter has not been able to quantitatively evaluate the field defect area with respect to the field inspection range.
By selecting a local visual field centering on a fixation target important for character recognition as an inspection range, the degree of visual field defect with respect to reading comprehension can be evaluated quantitatively in%. (See 200 and 202 in FIG. 20).
The retinal area, which has a high density of pyramidal cells, which is important for reading and recognizing text, is the foveal area, and the field-of-view inspection range can be extremely localized. Achieved. (See 200 and 202 in FIG. 20).
With familiar% display, the state of visual field loss is intuitively understood.
In addition to text reading / recognition recognition, a visual field inspection range such as a dark spot to a blind spot can be selected in advance, and the degree of visual field defect area relative to the inspection area can be evaluated quantitatively and objectively. (See 205 in FIG. 20).
The seriousness of the position of the dark spot area relative to the fixation point and the fovea is metrically displayed as a percentage and can be explained intuitively.
For program 2.
Regarding the method of selecting the corresponding visual field inspection range in measuring the degree of visual field defect impairment for reading / recognition of sentences in% units, for example, a character permutation similar in character shape in terms of spatial separation, such as yellow English, For example, the subject can actively move it left and right and up and down, and the range in which the subject can distinguish yellow and English is determined as the examination range. How to select the inspection range from the foveal point of view.
Alternatively, it is possible to select a horizontal inspection range and a vertical inspection range by moving the target target in the horizontal direction to the left and right for horizontal writing and the vertical movement for vertical writing. In that case, the vertical inspection range and horizontal inspection range are determined by the font size of the target. In this method, it is considered that the degree of visual field deficit with respect to reading comprehension is expressed with considerably different numbers in the case of reading comprehension for horizontal writing and for reading comprehension of vertical writing. This is because the traveling of the optic nerve axon has horizontal directivity. (See 200 and 202 in FIG. 20).
The importance of reading range recognition for horizontal writing and vertical writing in the horizontal and vertical directions, respectively, is symmetrical from the left and the right from the viewpoint of the retention of memory in human reading. I don't think so. (See 202 in FIG. 20). 66. A visual field inspection method used in the program 3 according to claim 65. In visual field inspections in which the static target is moved sequentially in the horizontal right direction every time it is confirmed that the subject has recognized, the subject will have a similar button press response in the field where the visual field is not impaired or in the dark spot blind spot field. Will continue. However, since the subject learns and memorizes the same button press response and uses that memory in the subsequent response process, even if the subject recognizes that the target is not visible, the person who uses the memory rather than recognition However, it is easy to make a wrong button response as if the target was visible. Even if the subject carefully presses the button so as not to make an incorrect response regarding the target recognition, immediately after making the same button response several times, the tendency to make an incorrect response is very high, In the case of a rough visual field inspection, the error due to the mistake is large. In addition, subject's carefulness to avoid false button responses leads to an increase in examination time. Therefore, in the visual field inspection method using the program 3 according to claim 65 of the present invention, in order to solve such a problem, unless the change in the visual sensitivity in the visual field is recognized, the subject keeps pressing the input button to select the visual target. It moves dynamically at the speed set in advance in the computer and releases the button only when the change in visibility is recognized, the dynamic target becomes a static target, and the subject actively moves the target in a slightly reverse direction The position is adjusted by moving to the forward or forward direction, and the visibility change point is determined by pressing the space key or the like. In areas where the visibility does not change, the subject does not respond by pressing the button every time it confirms that there is no change, but moves the dynamic target to the inside of the dark spot or blind spot area to some extent. This is a method for speeding up the visual field inspection by continuously pressing the input button. Since some position determination error is allowed at that time, the moving speed of the dynamic target can be set at a high speed. When the subject releases the input button once the subject recognizes that he / she has made a false response that the dynamic target has entered the dark spot or blind spot but the dynamic target is still visible, the high speed The dynamic visual target moving to becomes a static visual target. Requesting the subject to respond to the dark spot or blind spot at the moment when the visibility changes changes the response time to human stimuli, especially immediately after the same stimulus is repeated repeatedly. The response is quite unreasonable because the learning and memory effect of a response that has been repeated several times so far appears strongly and tends to be an incorrect response. However, it is easy for a subject to recognize immediately after an error response that an error response has been made to a different stimulus after the same stimulus repeated several times. After that, because the subject actively determines the position where the visibility changes due to the dark spot or blind spot area by moving the target to the left and right at low speed and correcting it, the shape of the extracted contour is very And accurately reflects the visual functioning state of the subject, such as the subject's dark spot and blind spot. The inspection result is shown on the display and is easy to understand intuitively. Since the subject only needs to respond to only the visibility change contour, by adjusting the size of the visual target and the moving speed of the visual target, a high-speed inspection with an inspection time of 5 minutes or less for a one-side visual field is possible. . A high-speed inspection that cannot be realized with a conventional perimeter, but if the inspection result is only a contour, a full-field retinal function scan program 1 view inspection result diagram (see FIG. 16 and the like) and claims. 60, an accuracy equivalent to that of the result of the very detailed visual field inspection program 2 (see 205 in FIG . 20) that actively sets the inspection range described in 60 is achieved. In the method of the present invention, in order to speed up the entire visual field inspection, the target is moved to a high speed at a speed set in the computer in advance and is used dynamically. The subject is passively controlled by computer control from the left end.However, in order to accurately extract the contours of visual function changes such as dark spots and blind spots, dynamic targets are static targets in the vicinity of the change in visibility. In addition, by using a dynamic visual target that moves at a low speed, the subject actively adjusts the visual target position in order to accurately extract the visibility change contour. Because it is a program, it is possible to refine the inspection result diagram or increase the inspection speed by adjusting the size and moving speed of the computer-controlled dynamic target. (See FIG. 15, FIG. 17, etc.). The field-of-view inspection method according to the program 3 according to claim 65 enables an inspection that is not affected by the judgment of the writer on the dark spot area of the subject and the prejudice, and maintains objectivity for the writer of the inspection result diagram. . In the case of the present invention program 3 .
The subject aims at speeding up the visual field inspection by adopting a method in which the subject is required to respond only to the dynamic visual target moving in the horizontal right direction when the change in the visibility is recognized. It is easy for the subject to recognize the appearance of discontinuous positions of the visibility on the dynamic target moving in the horizontal right direction. 66. A visual field inspection method used when using the program according to claim 65, which is a method using a characteristic that sensitivity to a human discontinuity start point is sensitive. Unless the change is recognized in the visibility, the subject keeps pressing the input button and keeps moving the dynamic target at a high speed, and does not respond one by one, so the examination time can be shortened. The subject can easily recognize that he has gone too far to the right of the visibility change position. After such recognition, the subject accurately determines the discontinuity of the visibility while actively moving the target around the discontinuity of the visibility and confirming it with the left movement button ← and the right movement button →. Press the space key to record the position. In the visual field inspection method using the program 3 according to claim 65, the test subject who is generated because the subject's target recognition confirmation leap time is converted into the active position adjustment time by the subject, so that the target recognition is accurately performed. As a result, the visual field inspection process is speeded up, and at the same time, the accuracy of contour extraction is achieved. Since it is a method that can be inspected while adjusting the position by recognizing that the target has moved too far in the right direction, etc., the temporal response during contour extraction by the subject The recording position error due to delay or the like can be reduced to zero. In the case of the present invention program 3 .
The response method of the subject to the visual field inspection of the present invention is not limited to the visual field, and can be applied to a general search for extracting features of interest from a wide range at high speed. The visual field inspection result is easy to understand and interesting because it is a feature outline extraction type (see FIGS. 17 and 15). By appropriately setting the size of the target, the moving speed, etc., it is possible to realize a one-eye full visual field inspection time of 5 minutes or less (see FIG. 17 and the like).
The program of the present invention determines the visibility change position with respect to the target in units of rows while dynamically moving the target in the horizontal right direction from the upper left corner of the display while keeping the center of the display as a fixed viewpoint. After scanning the vertical contour of the visibility change area by repeating the above, determine the visibility change position in units of columns while dynamically moving the visual target vertically from the lower left corner of the display. This is a method of scanning and extracting the horizontal contour of the visibility changing field by repeating in the right direction.
The output to the display is a method of synthesizing the vertical and horizontal contours, and as a result, the contour of the visibility change area scans only the vertical contour by dynamically moving the target in the horizontal right direction. It becomes clearer (see FIG. 21) than when extracted (see FIG. 15 and FIG. 17).
The program 3 uses a certain size of the target, so that the subject can determine the position of the target when the target is missing due to darkness, blind spot, etc. If it is determined in advance whether to determine the visibility change position, it is considered that the determination time for determining the visibility change position in the target recognition can be considerably reduced.
For example, FIG. 21, FIG. 15, FIG. 17, and the like show the test results when the subject has determined in advance that the visual loss is about 50% due to the visual field defect field to be the visibility change position. FIG.
In the programs 1 and 2 with small targets, the determination time for the degree of target loss was almost zero when determining the visibility change position, and thus it was not necessary to perform such consideration.
However, in visual field inspection, learning effects regarding the shape of dark spots and blind spots, which are accumulated according to the frequency of inspection and are effective for the accuracy of the inspection, can occur, and various features of visual function can be extracted. The subject can select such as the degree of target defect.
In addition, when the degree of target loss to be set as the visibility change position is clearly determined in advance, as is known from the visual field inspection result in FIG. Because there are unequal parts (see 62 and 66 in FIG. 21), it is possible to accurately observe a phenomenon in which the peripheral visual field such as the blind spot position is sequentially moved due to an increase in visual field inspection time.
In the case of the present invention program 3 .
The method of responding only to the position where the subject recognizes the change in the visibility in the visual field inspection is not limited to the visual field, and is a method that can be applied to a general search for extracting features of interest from a wide range at high speed. Part of a method that attempts to actively change the information processing speed adaptively to the characteristics of the target by processing the essential part at a low speed and processing the non-essential part at a high speed. It is. (See FIGS. 20, 21, 15, and 17.) The importance of this method stems from the phenomenon that it is not so easy for humans to flexibly convert their information processing speed according to the target. The results of the visual field inspection are shown in detail on the display by the program 1, program 2 and program 3 of claims 47, 60 and 65, and the shape of the visual field defect part and the shape of the blind spot are displayed on the computer screen. It was. Intuitively understand the severity of the dark spot area relative to the fixation point and the macular area. It is possible to display in detail such as the blind spot diameter enlarged state due to optic nerve depression.
The state of vision loss is difficult to explain to others, but by using the program according to claim 47, program 1, program 2 and program 3 according to claim 60 and claim 65, it is intuitive in a very short time. It becomes a state that can be explained.
According to the present invention, the program 3 according to claim 65, in which the visual field function state is illustrated in detail on the display by the method of actively selecting the area to be inspected, can detect a considerably fine spatial resolution, so from the dark spot to the blind spot. The glaucoma characteristics of about several minutes (see 62 in FIG. 21), which cannot be detected with the accuracy of a conventional perimeter, such that the connecting portion of the sensor is gradually thinned, are high for about several minutes because of the contour extraction type. Can be detected in speed. The relationship between Bjerrum area dark spots and blind spots, such as glaucomatous visual field defects and horseshoe-shaped dark spots, can be detected and displayed in great detail by the horizontal and vertical contour extraction scanning method.
The visual field inspection result diagram by the program 2 according to the present invention and claim 60 shows in detail the bending state of the dark spot area (see 205 in FIG. 20), which is very helpful when estimating the origin of the dark spot. become. The result of the inspection of the conventional basic perimeter does not show the degree of bending of the dark spot area.
According to the present invention, the program 3 and the visual field inspection method according to claim 65 make it possible to extract the contour of the bending state of the dark spot area in detail at high speed and display it on the display (60 in FIG. 21; FIGS. 15, 17). See). It is very helpful when estimating the origin of dark spots. The result of the inspection of the conventional basic perimeter does not show the degree of bending of the dark spot area.
According to the present invention, the program 2 and the program 1 according to claims 60 and 47, in which the visual field function state is illustrated in detail on the display by the method of actively selecting the field to be inspected, are provided in the field far from the fovea. It can detect and display a very detailed shape of the field defect area such as laser retinal.
The present invention, high-speed contour extraction of visual field functional state by passively moving and adjusting the target,
66. The program 3 and the visual field inspection method according to claim 65 shown on the display make it possible to detect and display the contour of a visual field defect region shape such as a laser retinal region in a region away from the fovea at a very high speed. To do. The program 2 according to claim 60 can shorten the inspection time by actively selecting the inspection range. On the other hand, in the contour 3 high-speed extraction type program 3 and the visual field inspection method, a region where the retinal visual function is not impaired or the feature to be observed is not discontinuous is obtained by passive high-speed visual field inspection using a high-speed dynamic visual target. Possible areas where the retinal visual function is impaired or the features to be observed are discontinuous can be converted from a dynamic visual target to a static visual target, and active visual field inspection can be performed at a low speed. Since the subject responds only to the contour portion, the examination time is greatly shortened.
The visual field inspection method of the program 3 according to claim 65, wherein the dynamic visual target moving at a high speed is once converted into a static visual target when the subject recognizes the discontinuity in the visual sensitivity. To adjust the position, the static target is converted into a dynamic target that moves at low speed. Since the visibility change recognition position is adjusted back and forth using a low-speed dynamic target, the position is determined accurately. After the position is determined, the low speed dynamic target is converted into a high speed dynamic target. In addition to the position for recognizing changes in visibility, even if there is a target inside the field such as a dark spot or blind spot, the test does not require a response from the subject one by one. Shortened to Since the visibility invariant portion uses a high-speed dynamic target, the inspection time is shortened from the viewpoint of the target recognition time. A method for extracting features of interest from a wide-range search object at high speed, or a general method for reducing the driving force of the work when it is necessary to sequentially understand or recognize a wide-range object. A method in which the search speed, understanding, or recognition speed is changed actively depending on the search or understanding target, and the search error, understanding, or recognition error can be greatly reduced. If it is a search, an object that diverges from interest and an object that can be inferred from tradition perform considerably high speed processing. If it is understanding, understanding of the object that can be inferred from the memory is performed at a considerably high speed. However, if it is a search, it will be a very slow process for an object of interest, a target that deviates from tradition, and if it is an understanding, an object that cannot be inferred from memory will take a considerable amount of time by taking a sufficient amount of time. , A way to try to achieve understanding or recognition. In understanding and recognizing, humans cannot understand the memory collation search time for understanding and recognizing flexibly and actively according to the object. Mistakes in understanding or recognition because it does not take the necessary reaction time. In understanding the object, the part inferred from the memory can be understood at high speed, but the part that cannot be inferred from the memory cannot be understood at all, but the superficial processing is continued, the uncertainty of definition accumulates in the processing, and the work is promoted. Derived from a phenomenon in which power is often reduced.
Since all of the programs of the present invention have simple inspection methods, it is possible to easily experience visual field inspection, observation of blind spots, etc. even at home. By visualizing and quantifying a subject's visual field state at home, explanation of the visual field state of the subject can be facilitated. In any program, since the inspection output result is beautiful, it is possible to relax by performing a visual field inspection for a certain period of time and looking at the output. A visual field area with a spatial resolution sufficient for character recognition can be detected at high speed, and the percentage of the visual field defect area such as a dark spot is intuitively displayed on the computer display as a visual function impairment level in character recognition. Programs that can be displayed.
In order to facilitate gaze, the visual field inspection range is determined by a method in which a target composed of letters, symbols, etc. is dynamically orbited slowly and circularly around a fixation target straddling two colors alternately.
First, the character target is around the fixed viewpoint.
The subject increases or decreases the orbital radius of the visual target. A method of setting the radius of the visual field inspection range as the radius that prevents the subject from clearly recognizing the target as a character on the resolution.
The selected circular visual field inspection range is a very important visual field for character recognition of the subject.
Perform a detailed visual field inspection for the area.
Since the inspection range is limited from the viewpoint of character recognition, the inspection can be performed in a very short time but in detail.
In addition, when the target only moves linearly, the position of the dark spot becomes an obstacle, and setting the upper limit or lower limit of the inspection range from the viewpoint of character recognition may be quite difficult for the subject.
However, the inspection range can be easily determined in a very short time by using a method of changing the orbital radius of the dynamic character target.
The result is a very constant value.
If the resolution is reduced to some extent, an inspection time of 5 minutes can be achieved, but that resolution is practical enough.
The ratio of the visual field defect area to the visual field inspection range set by the dynamic character target that performs the circular orbit can be displayed numerically by intuitive%.
The amount of obstacles due to visual field defects such as dark spots for character recognition can be displayed on the display.
The accuracy can be confirmed by the consistency of several-degree inspection.
Field inspection range setting method from the viewpoint of character recognition of the program that can display the visual field defect level in character recognition. A very detailed examination is possible by reducing the size of the target.
It is easy to understand because the visual field defect state can be displayed on the display.
A program that allows you to select the inspection range from the viewpoint of character recognition, perform visual field inspection at high speed, and display the visual field defect level and visual field defect state clearly and in detail on the display.
70. The program according to claim 69, wherein the seriousness of visual field loss for the subject can be displayed in% from the viewpoint of character recognition. A program A, a program B, a program C, and a program D of the present invention that can detect the position of the blind spot in the visual field of both eyes and the size of the blind spot at high speed and display them on the display.
The blind spot position of both visual fields and the size of the blind spot extracted by the circular orbit can be displayed on the display side by side (see FIG. 27). Program A, program B, program C, program D of the present invention.
The left-right difference in blind spot diameter can be calculated and displayed on the display in an intuitive manner, for example, the blind spot size of the right eye is 1.06 times the left eye (see 2 in FIG. 27). Program A and program B.
The program A of the present invention that makes it possible to intuitively compare the state of the left and right visual fields related to the blind spot with an approximate contour diagram (see 30 and 40 in FIG. 27) and numerals (see 2 in FIG. 27) on the display. Program B.
The degree of left / right asymmetry and left / right divergence (see FIG. 27) is information related to retinal stress, glaucoma, etc. in both the blind spot position and blind spot diameter.
Successful display of the position of the detected blind spot and the change of the blind spot diameter with respect to the examination time on the display (see FIG. 26). Program D of the present invention. 72. The program A, program B, program C, program D according to claim 71.
Blind spot inspection method of the present invention program A, program B, program C, program D.
For detecting the position of the blind spot, an * mark target (see 25 in FIG. 29) and a dynamic target (see 14, 22 in FIG. 29) that performs two inner and outer circular trajectories around the * mark are used. .
The blind spot diameter detection is a method in which two inner and outer circular orbit targets (see 14 and 22 in FIG. 29) centering on the mark * are adjusted while changing the trajectory radius.
For example, when testing is detected from the blind spot of the right eye field.
The left eye field is blocked and the central fixation target is fixed with the right eye.
The subject moves the green * mark near the fixation target to the right using the arrow keys.
Press the enter key at the position where the green * mark disappears.
Determine the position of the right eye blind spot. The green * mark disappears.
The fixation target will continue to be displayed.
The subject continues to stare at the fixation target (see 6 in FIG. 29).
Next, two circular orbits appear on the inner and outer sides around the purple mark (see 25 in FIG. 29) (see 14, 22 in FIG. 29).
The purple * mark appears at the center position of the blind spot detected by the previous green * mark.
The inner circular orbit (see 22 in FIG. 29) is a green target that dynamically performs a circular orbit.
The outer circular orbit (see 14 in FIG. 29) consists of a red visual target that dynamically performs a circular orbit.
When trying to conduct a more accurate inspection.
In order to detect the blind spot position more accurately, the purple * mark (see 25 in FIG. 29) is set to appear at a position slightly away from the previous green * mark.
When the purple * mark can be recognized in the peripheral visual field, the subject uses the arrow keys to move the purple * mark to within the blind spot.
When moving the purple * mark, in the present invention program A, program B, program C, and program D, the two inner and outer circular orbits centered on the purple * mark (see 25 in FIG. 29) are also the same distance and in the same direction. This is a method of moving (see 14, 22 in FIG. 29).
Two circular orbits (see FIGS. 14 and 22 in FIG. 29) have a function of easily speeding up the approximate diameter detection of blind spots (see 30 and 40 in FIG. 27).
The detection error of the blind spot diameter can be limited as compared with the case of using one circular orbit.
The blind spot contour radius detection error can be limited within a radial distance difference between the two inner and outer circular orbits.
For example, when using only the inner green circle orbit.
When adjusting the green circle orbit within the blind spot area, even if the green circle orbit radial distance is made too short by pressing the B key too much, the subject cannot recognize the degree.
This is because the green circle orbit is already within the blind spot area.
However, as in the present invention program A, program B, program C, and program D, a red circular orbit (centered on the same purple mark *) is located outside a certain distance from the green circular orbit (see 22 in FIG. 29). In the case where there is 14) in FIG. 29, if the radius is made too short, the outer red circular orbit (see 14 in FIG. 29) enters the blind spot area. At that time, since the subject can recognize the defect of the red circular orbit in the field of view, the subject can recognize that the radius has been reduced too much.
The subject can adjust with the H key to increase the radius.
The blind spot inspection method of the program A, program B, program C, and program D of the present invention starts with a trajectory by pressing the B key until the inner green circle orbit (see 22 in FIG. 29) becomes invisible within the blind spot area. Reduce the radius.
However, the position of the outer red circular orbit (see 14 in FIG. 29) is adjusted by adjusting the position and moving radius by pressing the B key or H key so that the subject can see around the blind spot area.
The B key or H key has a function of reducing and increasing the radius of the inner and outer double circular orbits (see 14 and 22 in FIG. 29) by the same distance.
The subject adjusts the inner green orbit (see 22 in FIG. 29) within the blind spot area and the outer red orbit (see 14 in FIG. 29) outside the blind spot area.
The blind spot radius detection error can be limited to the radial distance difference between the outer circular track and the inner circular track.
For more detailed inspection, more accurate blind spot position, and blind spot diameter approximation, set the orbital radius to the B key or H so that the inner green circle orbit (see 22 in FIG. 29) remains slightly around the blind spot. Adjust with key. Adjust the green dynamic target around the blind spot so that the subject can recognize it.
If the green distribution recognized around the blind spot has a deviation depending on the direction, the subject adjusts it with an arrow key or the like so that the green distribution is as free as possible.
The green distribution (see 22 in FIG. 29) by the circular orbit dynamic target visible around the blind spot is uniformly distributed, and the corona green distribution with respect to the circumference of the blind spot is averagely balanced. It can be detected.
Thereafter, the orbital moving radius is further reduced and adjusted to such an extent that the green color (see 22 in FIG. 29) becomes invisible due to a blind spot.
The outer red circular orbit (see 14 in FIG. 29) is visible around the blind spot.
Adjust the position with the arrow keys so that the corona-shaped red circular orbit is as homogeneously distributed as possible around the blind spot.
Adjust the trajectory radius by B key or H key.
This is a method capable of accurately detecting the blind spot diameter.
As a result of the inspection, the left and right blind spot states can be displayed in parallel on the left and right sides of the fixation target center on the display.
The left-right difference in the position of the blind spot and the left-right difference in the blind spot diameter scale are intuitively displayed on the display (see FIG. 27).
When changing the size of the target for carrying out the circular orbit (see 30, 40 in FIG. 27), the influence of the size of the target on the detection blind spot area increase / decrease can be seen.
The programs A and B of the present invention can calculate the diameter ratio of the left and right blind spot approximate contours (see FIG. 27).
The difference in the size of the left and right blind spots can be evaluated numerically (see 2 in FIG. 27).
For example, if the right eye blind spot is larger, the program of the present invention calculates the right blind spot diameter / left blind spot diameter.
If the result is 1.06, the diameter of the right blind spot is 1.06 times the diameter of the left blind spot.
The right blind spot is 6% larger than the left blind spot.
The left-right difference in blind spot diameter can be expressed intuitively and intelligibly (see 2 in FIG. 27).
In the left and right blind spot comparison, the relative degree of glaucoma is grasped.
The left-right blind spot comparison represents the effects of intraocular pressure, axial length, stress on the retina, and adverse effects on visual function (see 2 in FIG. 27).
In the present invention program A, program B, program C, and program D, the blind spot area contour is approximated by a circular orbit.
This is because the blind spot diameter can be detected at a high speed.
When a blind spot is approximated from the inside by a green circular orbit, the blind spot minimum area is extracted when a blind spot that is not completely circular is approximated from the inside by a circular orbit.
When a blind spot is approximated from the outside by a red circular orbit, the maximum blind spot area is extracted when a blind spot that is not completely circular is approximated from the outside by a circular orbit.
In the program B of the present invention, the detected inner green circle orbit and outer red circle orbit can be collectively displayed on the display as a result of such a blind spot inspection (see FIG. 28).
The deviation of the bi-circular orbit represents the degree of deviation of the blind spot area from the circular orbit.
To inspect the degree of deviation of the blind spot area from the circular orbit, first move the inner green circle orbit completely within the blind spot area. To be precise, the corona green distribution seen around the blind spot is adjusted with the arrow key, B key or H key so as to make the circumference uniform.
Thereafter, the subject adjusts the trajectory radius using the B key or the H key so that the red circular trajectory is completely outside the blind spot area.
However, there is distortion in visual recognition around the blind spot.
The phenomenon may represent distortion such as unevenness of the retina.
May represent glaucomatous characteristics.
Program B showing the area with distortion around the blind spot on the display, which represents the area with distortion around the blind spot.
To do so, first move the inner green circle orbit so that it is completely within the blind spot area.
To be precise, the position is adjusted while making the corona green distribution visible around the blind spot uniform.
Thereafter, the subject adjusts the trajectory radius so that the red circular trajectory is completely outside the blind spot area.
However, the trajectory radius is increased by the H key to such an extent that the subject can recognize the red circular trajectory as a complete circular trajectory (see 36 in FIG. 28).
The subject can recognize a complete circular orbit because the visual recognition is distorted around the blind spot, so the red circle orbit is not recognized as a circular orbit immediately around the blind spot, and the trajectory is distorted or a trajectory defect occurs. This is because there is a region (see 62 in FIG. 28).
When the visual field inspection is continued with the fixation target gaze, the position of the blind spot always moves little by little (see 5 in FIG. 26).
The size of the blind spot always changes little by little (see 15 in FIG. 26).
The program D of the present invention which can display the movement and change state on the display.
In order to reflect the temporal movement of the blind spot position and the temporal change of the blind spot diameter scale on the display, the inspection speed is increased. Perform blind spot detection to some extent.
However, it is accurate because it uses two inner and outer circular orbits.
Easily detect blind spot position diameter.
For example, when detecting the degree of blind spot change with respect to the visual field inspection time of the right eye.
The subject blocks the left eye field and stares at the central fixation target with the right eye.
Move the green * mark target in the center fixation target to the subject's blind spot area by moving it to the right side with the arrow keys.
Press enter when the green * mark is not visible in the field of view. The green * mark disappears.
The fixation target continues to be displayed (see 6 in FIG. 29).
The subject continues to stare at the fixation target.
A purple * mark target (see 25 in FIG. 29), and two inner and outer circular orbit targets (see 14, 22 in FIG. 29) appear.
The program C of the present invention is used to accurately detect the blind spot position fluctuation.
A purple mark * (see 25 in FIG. 29) is set so as to appear in the vicinity of the fixation target (see 6 in FIG. 29).
The subject must move the purple mark (see 25 in FIG. 29) from the vicinity of the fixation target (see 6 in FIG. 29) to the blind spot at every examination.
In this method, the center position of the blind spot detected by the subject is not affected by the test result regarding the blind spot position so far.
However, when paying attention to the time change of the blind spot, the present invention program D is used.
From the viewpoint of reducing the examination time, the purple * mark (see 25 in FIG. 29) appears approximately at the position of the blind spot detected by the examination results so far, and is a method of reducing the position adjustment time by the subject.
However, the inner and outer circular orbits (see 14 and 22 in FIG. 29) are displayed by increasing the moving radius to some extent at each inspection.
Since the radius is increased to such an extent that the subject can recognize the inner green circle or outer red circle, the inner green circle orbit (see 22 in FIG. 29) is completely within the blind spot area every time the examination is performed. Adjust the trajectory radius so that
When the trajectory radius is reduced by the B key, the radius is reduced and the position is adjusted while adjusting the position so that the corona green distribution is uniform around the blind spot, and attention is paid to the corona balance of the green distribution around the blind spot.
For example, when the blind spot tends to move to the ear side with the examination time, when the trajectory radius is reduced by the B key, the green circle orbit on the circumference of the blind spot is just before the green circle orbit becomes invisible. The distribution is recognized with bias toward the nose.
In that case, the green circle orbit is moved to the ear side by an arrow key or the like.
Average the green corona balance around the blind spot.
In this method, the green corona distribution recognized by the subject around the blind spot is adjusted so that it is as homogeneous as possible around the circumference.
A system that adjusts to create a corona with a green orbit that is homogeneous around the circumference of the blind spot.
This is a method of adjusting the trajectory radius so that the inner green circle orbit becomes invisible due to the blind spot, but the outer red circle orbit appears homogeneous around the blind spot.
Use the B key or H key to determine the blind spot position and blind spot radius.
Press enter.
By repeating the same examination, the program D of the present invention can show the time transition of the blind spot position and blind spot diameter on the display (see 5 and 15 in FIG. 26).
Since the results of repeated inspections of the blind spot position and blind spot diameter in the visual field are overwritten on the display, the temporal transition state of the blind spot position is well understood (see 5 in FIG. 26).
The display color of the blind spot outline is changed with time (refer to 5 and 15 in FIG. 26).
The blind spot position moves, for example, in the horizontal ear direction in proportion to the length of the examination time (refer to 5 and 15 in FIG. 26).
However, fluctuations may occur in the moving direction (see 5, 15 in FIG. 26).
The detected blind spot diameter may also fluctuate depending on the length of the examination time (refer to 5 and 15 in FIG. 26).
However, in the overwriting, the previous blind spot position motion described in duplicate on the display cannot be grasped.
In order to improve the state where the fluctuation is not reflected on the display when the movement of the blind spot position fluctuates not only in one direction but also in the opposite direction, the change of the blind spot position and the blind spot radius with time is displayed in an intuitive graph.
It is the graph display which makes time a coordinate axis.
The information regarding the blind spot position and blind spot radius is a graph that collectively displays in the direction perpendicular to the time coordinate axis (see 15 in FIG. 26).
It has been observed that the detected blind spot position is horizontally moved sequentially in proportion to the time (see FIGS. 5 and 15).
However, there are cases where the blind spot position does not move in proportion to time and is not flexible.
The blind spot diameter may increase with time (see 5, 15 in FIG. 26).
The phenomena displayed on the display by the program D of the present invention, such as the degree of flexibility in moving the blind spot position with respect to time and the degree of change in the blind spot diameter scale (see 5, 15 in FIG. 26), May represent a feature.
The present invention program A, program B, program C, and program D can select the detection blind spot diameter error degree by changing the radial distance difference of the inner and outer circular orbits.
The target can be selected to an appropriate size for the program. The program of the present invention that enables a subject to select a visual field inspection range while viewing his / her visual field deficit and visual function deterioration state on a display.
The program of the present invention is a method in which the display is alternated in two colors at appropriate time intervals in order to make the subject recognize his / her visual field loss and visual function deterioration state.
The system of the present invention program is particularly effective when the subject has glaucoma characteristics, when the retina has a cone cell density-decreasing portion, or when the blind spot diameter is increased due to intense myopia.
In order for a subject in such a state to recognize a visual field defect state, red-orange and black alternate display is particularly effective.
By the method of the present invention program, the subject can recognize the presence / absence of the visual visual function deterioration part and the visual field defect part from the display color defect, such as the shape and the positional relationship with the fixed viewpoint.
When two-color display of the display color is performed alternately at an appropriate time interval, the visual function degradation area such as the dark spot and the blind spot diameter enlarged portion cannot follow the change in the display color in time, and remains as an afterimage. A dark spot, a blind spot diameter enlarged part, etc. are recognized by the subject as a color defect on the display.
Using red-orange-black color, which is difficult to follow visually, the subject can see the shape of the visual function-decreasing region such as the blind spot blind spot on the display, including the peripheral visual field, in considerable detail.
The field of interest will be clear and the visual field functional scan inspection range can be selected very easily.
The program of the present invention can move the fixation target, and the subject can move the visual field of interest near the center of the display. This is useful when the field of interest is recognized at the edge of the display.
In order to record the subject's visual field condition visually recognized as a color defect on the display to the computer in a reproducible and high-resolution manner on the computer, a visual field function scan using static dynamic diopter is performed. Use.
In the program of the present invention, the subject can move the fixation target while looking at his / her visual field defect state on the display, and can move the examination target visual field to the center of the display, This is useful when the inspection object does not fit in the display.
Since the subject can limit the examination range while viewing his / her visual field defect state on the display, the resolution of visual field visual function scanning can be increased while shortening the examination time.
Therefore, the shape of the dark spot blind spot, the shape of the connection part of the dark spot blind spot, and the like are reproduced and recorded very finely on the display.
The visual field function scan uses a dynamic target to speed up the visual field inspection.
The target moving speed can be selected from the viewpoint of reducing the inspection time, such as decreasing the target moving speed when inspecting a narrow range in detail, or increasing the target moving speed when inspecting a wide range.
In the program of the present invention, the high-resolution visual field visual function scan result diagram obtained in a short time by limiting the examination range can be used accumulatively.
It is possible to synthesize and display on the display a diagram of the results of short-time inspections performed in multiple times.
Short-term visual field inspection has less burden on the subject.
The subject can adjust the distance from the display to the subject by matching the composite view of the results up to the previous examination displayed on the display with the size and positional relationship of the blind spot blind spots visually recognized by the subject. It is possible and may reduce the composite deviation from subsequent inspection of the visual field functional scan diagram.
While performing visual visual function scanning without interruption in the horizontal direction, the static visual target is detected as long as the subject's ability to react to the visual target recognition is established in order to detect the spatial separation ability equivalent to character recognition and reflect it in the inspection result. The waiting time is set until becomes a static dynamic target. 75.

Decreasing the size of the target increases the detection ability for the central visual field visual function.
74. The program according to claim 73, wherein the subject can be requested to have a different target recognition reaction in order to increase the visual field visual function extraction capability depending on whether the examination range is the central visual field or the peripheral visual field.

The program of the present invention according to claim 73, wherein the target visual target can be programmed to scan and move in the right direction.

The program A of the present invention according to claim 75, wherein the response criterion required by the subject is a very simple criterion that the subject presses the space key when the subject can recognize the movement of the target in the visual field.
The horizontal spatial resolution is measured using only the dynamic visual target, but in order to measure the central visual field spatial resolution in more detail, the two targets of the static visual target and the dynamic visual target are alternately used. 76. The program A of the present invention according to claim 75, wherein the program can be set so as to measure the horizontal spatial resolution.

In this method, the two visual markers are different in the central visual field spatial resolution measurement, and the movement of the visual target is recognized in the peripheral visual field spatial resolution measurement.
The method of using two targets for measuring the spatial resolution of the visual field is that when the movement of the target is recognized in the visual field, the dynamic target moving in the horizontal direction by the space key pressed by the subject is When the static target is converted into a static target and the static target is displayed, a similar dynamic target starts moving from that position in the horizontal direction, and the subject recognizes the movement of the target in the field of view or By pressing the space key when the static dynamic two targets can be identified, the distance from the static target position to the dynamic target position at that time can be converted to the computer as a spatial resolution. The static target that was recorded and displayed disappears from the display, and at the position where the space key is pressed, the dynamic target becomes the static target, and the static target is displayed. A similar dynamic target starts moving in the horizontal direction. By repeating the processing described is a method of accumulating the spatial resolution information for viewing 2D.
The distance between the static visual target and the dynamic visual target thus measured is considered to reflect the spatial resolution, cone cell density, visual cortex function, etc. at the position on the retina.
In the above-described method, the present invention program A according to claim 75 is set so that the static visual target is not displayed.
From the viewpoint that the effective pyramidal cell density is fundamental, the possibility of recognizing the target movement and the possibility of distinguishing the two visual signs are considered to be approximately equivalent phenomena.
However, in the peripheral visual field, the influence of temporal habituation on vision may occur with respect to the possibility of distinguishing two visual markers. 78.

In the visual field test result diagram, the dark spots and blind spot connection parts are considered to be important in detecting normal-tension glaucoma characteristics or initial stage glaucoma characteristics derived from advanced myopia. Since it is away from the fixation target, it is difficult for the subject to set the inspection range including those portions accurately and at high speed.

The visual field inspection program of the present invention according to claim 101, wherein the state can be displayed on the display in detail and cleanly. By performing the visual field inspection in great detail, the retinal structure such as optic nerve axon running and vascularity is recalled from the position shape of the visual field defect area such as the dark spot obtained as a result, and visual field defect occurs in the visual recognition of the subject 102. The visual field inspection program of the present invention according to claim 101, which prompts the user to infer what is the cause or the like.
102. The visual field inspection program of the present invention according to claim 101, wherein the visual field inspection program is intended to perform not only a state in which a visual field defect of a subject can be transmitted but also a detailed visual field inspection so that the cause of the visual field defect can be estimated. In particular, when performing a visual field inspection in great detail, the subject often has to repeatedly perform the same response in a certain inspection range.
In such a case, when there is a change in the visual recognition of the subject with respect to the optotype and the optotype recognition response must be changed accordingly, the memory of the repetitive response so far prevents the subject from changing the response quickly.
The phenomenon that the memory response speed exceeds the cognitive response speed and increases the error becomes more apparent as the visual field inspection is performed at a higher speed. 102. The visual field inspection program according to claim 101, which tries to avoid such a response error. When a subject tries to generate a clear visual field inspection result diagram with no errors, and the subject tries to perform a visual field inspection with no error in the target recognition response, the response sequence is always considered in the reverse direction. The inspection speed is greatly reduced.
The field-of-view inspection program according to claim 101 is a method of displaying a guide consisting of four line segments around a static visual target, thereby greatly reducing the accuracy of the inspection result while greatly reducing the time required for visual field inspection. Try to increase.   102. The visual field inspection program of the present invention according to claim 101, wherein a moving interval of a static visual target moving in a constant direction such as a horizontal direction can be increased in order to perform visual function inspection of the entire visual field in a very short time. The visual field defect area along the optic nerve axon running and vascularity, which is considered to be important for detecting normal-tension glaucoma characteristics derived from advanced myopia or detecting glaucoma characteristics at the initial stage, as a detailed examination field of view Even if you try to set the range, the subject will set the range accurately, for example, because such a part is far from the fixation target, or the visual function of such a part may be at a low level. That is not easy.
According to the visual field inspection program of the present invention described in claim 101, an area where the visual function along the optic nerve axon running, vascularity, etc. is slightly lowered can be observed as a display color defect.
The visual field inspection program of the present invention according to claim 101 facilitates setting of the visual field inspection range of the subject by alternately displaying the display colors in two colors.
According to the visual field inspection program of the present invention as set forth in claim 101, the subject can set the inspection range so that the visual field inspection can be performed in detail on the part of particular interest while looking at his / her visual field visual function deterioration state on the display. When a very detailed visual field inspection is performed using a static target that sequentially moves in response, a subject often has to repeatedly perform a similar response within a certain inspection range.
This is because in the case of a very detailed visual field inspection, the visual recognition of the subject with respect to the static visual target is constant within a certain range.
In such a case, the subject has a change in the visual recognition of the static target, and when the target recognition response is to be changed accordingly, the same repeated response is stored in memory. A phenomenon occurs in which memory affects response rather than recognition.
As the subject increases the response speed and shortens the visual field inspection time, the memory response exceeds the cognitive response, resulting in an increase in response error.
When the response speed is increased by the subject, the visual recognition is memorized by the response error several times and becomes available for the response, so the memorized response becomes equivalent to the recognizable response and the number of errors is limited.
However, the recognition that the response to the target recognition is error and the recognition by the subject that the recognition and the memory response have deviated in the visual field defect partial contour affect the driving force of the subject with respect to the visual field inspection.
The inspection result diagram also has a slight error in the outline of the visual field defect region.
The phenomenon that the memory response speed exceeds the cognitive response speed and increases the error becomes more apparent as the visual field inspection is performed at a higher speed. 102. The visual field inspection program according to claim 101, which tries to avoid such a response error.
The field-of-view inspection program according to claim 101 is a method of displaying a guide consisting of four line segments around a static visual target, thereby greatly reducing the accuracy of the inspection result while greatly reducing the time required for visual field inspection. Try to increase. In order to guess what is causing the visual field defect area, etc., it is necessary to consider the position and shape of the visual field defect area from the relationship with the retinal structure, etc. There is a need to do.
If a very detailed visual field inspection is performed, it is practical from the viewpoint of inspection time to limit the inspection range.
However, if the subject cannot recognize the position and shape of his visual field defect region when setting the examination range, it is impossible to limit the visual field examination range appropriately.
In order to accurately select the visual field range to be subjected to visual field inspection, it is necessary that the subject can refer to his / her visual field visual function state on the display in some detail before setting the range.
The visual field inspection program of the present invention according to claim 101 is a method that allows a subject to set a visual field inspection range while viewing his or her visual field defect state on a display.   The field-of-view inspection program according to claim 101 is a method in which the subject is particularly interested from the display color defect region by the method of alternately displaying the display background color in red-orange and black at a preset short time interval. Can be selected as the visual field inspection range. The visual field inspection program of the present invention according to claim 101 enables the subject to grasp the visual function deterioration region of the subject as a display color defect including the visual field defect region far from the fixation target.
According to the visual field inspection program of the present invention according to the 101st aspect, the subject can see the visual function-decreasing region of his visual field as a color defect on the display. As a normal-tension glaucoma characteristic derived from advanced myopia, or as an early stage glaucoma characteristic, the area where the visual function along the optic nerve axon running, vascularity, etc. is considered to be important, According to the visual field inspection program of the present invention, the display color defect can be observed. In order to increase the inspectable visual field range, the visual field inspection program according to the present invention can move the fixation target before setting the visual field inspection range.
The program for inspecting visual field of the present invention according to claim 101, wherein the subject moves the fixation target so that a portion of particular interest is as centered as possible while viewing the position and shape of the visual function-decreasing region in his visual field on the display. Can be made.
The visual field to be inspected can be moved to the center of the display as much as possible.   According to a 101st aspect of the present invention, the visual field inspection program records the static visual field loss and the visual function deterioration state of the subject on the display and displays them on the display. Use a target. First, the subject blocks the visual field on one side and stares at the fixation target with the other visual field.
The visual field inspection program of the present invention according to claim 101, in response to a static visual target displayed on the display, each time a response indicating that the subject is recognizable or unrecognizable is made, the static visual target is sequentially displayed in the horizontal direction. For example, when the predetermined line is moved at a predetermined interval and the inspection of one line is finished, the inspection of the next line is similarly started.   For the purpose of increasing the speed of visual field inspection and reducing the target recognition response error by the subject, the visual field inspection program according to claim 101 is sequentially applied to the periphery of the static visual target that is sequentially moved by the subject. You can also display a guide that moves in parallel. In the visual field inspection program according to the 101st aspect of the present invention, guide is composed of four line segments in the vertical and horizontal directions centering on the static visual target.
The four relatively short guide line segments are separated from the static visual target at the center by a certain distance in order to be separated from the static visual target in the visual recognition.
In order to separate the static target and the four guide segments for visual recognition, when the static target is displayed in green, for example, the four guide segments are displayed in reddish orange.
The red-orange display of the guide that sequentially moves in response to the test subject's target recognition may be sensitive to the visual function degradation area. 101. The visual field inspection program according to claim 101, wherein four guide segments are used.
The guide line segment increases the speed and accuracy of visual field inspection.
The guide line segment allows the subject to recognize the visual field state around the sequentially moving static target. 101. The visual field inspection program according to claim 101, wherein four guide segments are used.
For example, when the vicinity of a dark spot region in the central visual field is inspected by a sequentially moving static target having four guide segments, a sequentially moving static target having a green display is seen, but four guides are visible. The subject can recognize in advance a state in which any of the line segments is partially reddish orange.
Therefore, the subject can recognize that there is a visual field defect region in the vicinity while recognizing the sequentially moving static visual target displayed in green.   The visual field inspection program of the present invention according to claim 101 allows the subject to predict the visual field state around the static visual target and allows the subject to change the visual target recognition response speed accordingly. 101. The visual field inspection program according to claim 101, wherein four guide segments are used.
The subject can recognize in advance the outline portion of the visual field defect region by the four guide line segments. Only in the contour portion, the test subject slightly reduces the response speed to the target recognition, and the response error by the test subject is greatly reduced. This is because most of the response error by the test subject occurs only in the visual field defect outline.
Four guide segments greatly increase the accuracy and ease of visual field defect contour extraction.
Alternatively, since the position of the visual field defect region can be predicted in advance by four guide segments, the response error can be reduced without a decrease in response speed. 101. The visual field inspection program according to claim 101, wherein the method uses four guide segments.
The subject's response to the visual change of the target recognition is not easily affected by the memory of the previous repeated response.
This is a phenomenon in which the recognition of the guide line segment defect exceeds the memory of the repeated response.
This is because the recognition of the guide line segment defect is memorized to some extent.
When using the visual field inspection program of the present invention according to claim 101 and the four guide segments, the subject can display his / her visual field state in a very high speed and on the display in a beautiful manner. When using the four visual field inspection programs of the present invention according to claim 101, it is possible to inspect whether or not the subject can clearly recognize the static visual target with respect to the four guide line segments. .
In the central visual field, the static visual target can be clearly recognized at the center of the four guide line segments.
However, when moving sequentially to the peripheral visual field, it is also possible to detect a range in which the recognition of the static visual target for the four guide segments becomes unclear. 101. The visual field inspection program according to claim 101.
In order to grasp the visual function of the entire visual field in a very short time, the sequential movement interval of the static visual target is increased.
Even if the interval of the static target is large, if the size of the static target is very small, a visual field inspection that can detect even a slight deterioration in visual function is performed in a very short time. It is possible. The subject's precise and detailed visual visual function is incapable of being transmitted.
However, the subject's visual field state is most recognizable by the subject.
The subject can recognize an approximate position shape as long as it is a dark spot in the central visual field that is close to the fixation target.
However, in the case of an imaginary dark spot, the position shape of the dark spot cannot be accurately recognized even by the subject unless the position is very close to the fixed viewpoint.
The field-of-view inspection program according to a 101st aspect of the present invention performs two-color alternate display such as red-orange, black, etc. with an appropriate short time interval for the display background color.
According to the visual field inspection program of the present invention according to the 101st aspect, the test subject can see an area in which the visual deterioration is caused in his visual field as a color defect of the display.
In the visual function deterioration region, it is considered that this phenomenon is caused by delay in visual follow-up to the color change of the display.
By the visual field inspection program according to the 101st aspect of the present invention, the subject can see the visual field defect area including the imaginary dark spot and the visual function lowered area as the display color defect in detail.
By the visual field inspection program of the present invention according to the 101st aspect, the subject can see the running and shape of the visual field defect region considered to be derived from the retinal structure or the like in advance on the display before the visual field inspection.
The visual field inspection program of the present invention according to claim 101 suggests that the shape of the display color defect region that the subject can see on the display is very continuous, and the visual field defect region is due to the retinal structure or the like.
Compared to the conventional perimeter inspection results, it is possible to observe a very continuous display color defect shape. The subject can recognize not only the central visual field but also the peripheral visual field by using the visual field inspection program according to the present invention. The subject can see the visual function-decreasing region of his visual field as a color defect on the display.
As the normal-tension glaucoma characteristic derived from advanced myopia, or the glaucoma characteristic in the initial stage, the area where the visual function is slightly decreased along the optic nerve axon running, vascularity, etc. According to the visual field inspection program of the present invention, the display color defect can be observed. When the visual field to be inspected is at the end of the display, the visual field inspection program according to the 101st aspect of the present invention attempts to increase the visual field inspection possible range by moving the fixation target.
In the visual field inspection program according to the 101st aspect of the present invention, the subject can move the fixation target so that it is as close to the central visual field as possible while viewing the position of the visual function degradation region on the display. If the display color alternate color display is not performed, since the dark spot and blind spot connection part is far from the fixation target, the subject cannot recognize the state of the position in detail, and the examination range can be set accurately. difficult.
In the field-of-view inspection program according to the 101st aspect of the present invention, it is very easy to select a dark spot / blind spot connection portion as an inspection range by two-color display alternate display.   101. The visual field inspection program according to claim 101. It is very easy to set a portion showing a shape of interest from the display color defect portion as the visual field inspection range. 101. The visual field inspection program according to claim 101.
If the visual field inspection range is narrowed, even a very detailed visual inspection can be performed in a very short time. A very detailed visual field inspection result diagram reflects the retinal structure and the like.
By displaying visual field test results that are as detailed as visual cell units or ganglion units, such as cones, on the display, the relationship between the subject's visual field deficit, the optic nerve axon travel, and vascularity of the subject can be estimated in detail. .
The visual field inspection program of the present invention according to claim 101 not only makes the visual field defect state of the subject transmittable but also makes it possible to estimate the cause of the visual field defect. When using the field-of-view inspection program according to the 101st aspect of the invention and using four guide segments, the response error is greatly reduced and the accuracy of the field defect contour extraction is greatly increased.
This is a phenomenon in which the recognition of the guide line segment defect exceeds the memory of the repeated response.
This is because the recognition of the guide line segment defect is memorized to some extent. When using the visual field inspection program of the present invention according to claim 101 and four guide segments, the subject can recognize that the static visual target has approached the dark spot portion.
If the static target is far from the dark spot, it responds to the high speed using the response memory up to that point, and when the static target approaches the dark point, the subject can recognize four guide line segment defects in advance. , It is possible to bypass the memory of repeated responses until then, slightly lower speed, slightly longer target recognition judgment time, responding in detail, etc. The subject can select the response speed, almost completely error It is possible to determine the outline of a dark spot without a visual field or a visual field defect region.
A very accurate visual field defect region contour result can be obtained without adjusting the position of the visual field defect region contour position by the subject.
Alternatively, the four guide segments allow the subject to predict the dark spot position around the static visual target, which may reduce the error without reducing the response speed. However, the accuracy of the inspection result increases.   When using the visual field inspection program of the present invention according to claim 101 and four guide line segments, the visual field state of the subject can be displayed on the display at a very high speed. With the four guide segments, the subject can confirm during visual field inspection that his visual field characteristics can be detected very accurately. 101. The visual field inspection program according to claim 101, wherein four guide segments are used.
The four guide line segments are particularly effective when the position shape of the visual field defect region is to be detected in detail in the central visual field. 101. The visual field inspection program according to claim 101, wherein four guide segments are used.
It is also possible to detect whether or not the static visual target can be clearly recognized at the central part of the four guide line segments around it.
It is thought to be related to the spatial resolution.
In the vicinity of the central visual field and the fixation target, the static visual target can be clearly recognized in the central portion of the four guide line segments.
However, when the static target moves sequentially to the peripheral visual field, there is a range in which the static target for the four guide segments becomes unclear.
The range can be extracted.
Alternatively, it is possible to perform visual field inspection to extract visual functions at other levels by adjusting the four guide line segments to be thicker or the size of the central target to be increased. 101. The visual field inspection program according to claim 101.
When the sequential movement interval of the static visual target is increased, the entire visual field can be inspected in a very short time.
The entire field of view can be grasped. 101. The visual field inspection program according to claim 101.
Even if the interval of the static target is large, if the size of the static target is made very small, it is possible to detect areas where the visual function has deteriorated to a considerably low level while performing high-speed inspection. It is. 101. The visual field inspection program according to claim 101.
By slightly increasing the sequential movement interval of the static visual target, the visual field inspection time is considerably shortened. 101. The visual field inspection program according to claim 101.
If the display background color two-color alternating display time interval is changed, the detectable visual function deterioration level can be changed.
This is considered to be because the speed of visual color tracking with respect to a change in the display background color changes depending on the degree of visual function deterioration due to a decrease in cone cell density or the like.
According to the field-of-view inspection program of the present invention, it is possible to set the display background color display time and how many milliseconds of red-orange and how many black.
The combination of two display background colors can be changed to another combination by the visual field inspection program according to the present invention. 101. The visual field inspection program according to claim 101.
By changing the size of the visual target and the color luminance, it is possible to extract a visual function-decreasing region at another level from the subject visual field and display it on the display. 101. The visual field inspection program according to claim 101.
For example, when the target is made very small, a visual field defect region that is located in the central visual field can be detected in great detail.
The possibility of detecting an area where the visual function is slightly reduced is also increased.
In the case of enlarging the visual target, it is possible to detect positions and shapes such as dark spots and blind spots for the entire visual field, and to detect a significant change in visual function in the peripheral visual field beyond the blind spot. When using the visual field inspection program of the present invention described in claim 101 and four guide segments, the size of the static visual target as well as the four guide lines around it are determined by the visual field inspection program of the present invention according to claim 101. The thickness of the minutes can be adjusted.
As the guide, in addition to the four guide segments, a circle display centering on a static target may be considered. 101. The visual field inspection program according to claim 101.
If the target movement interval is increased, even the inspection of the entire visual field can be realized in a very short time.
The entire field of view can be grasped.
Even if the optotype movement interval is large, if the size of the static optotype is made very small, it is possible to detect a considerably low level visual function degradation region while performing high-speed inspection.
If the target movement interval is slightly increased, the inspection time is considerably shortened.
The inspection result diagram displayed on the display by the visual field inspection program of the present invention according to claim 101 can be stored in a computer and can be compared in time series.   The present invention static optotype which enables normal computer to detect a normal visual pressure glaucoma derived from advanced myopia, or a visual field area slightly deteriorating in visual function, which is considered to be characteristic of the initial stage of glaucoma .   The perimeter program of the present invention that makes it possible to display in detail the shape of the visual function deterioration region on the display using the static target of the present invention according to claim 156. Since the conventional perimeter has low resolution, normal visual pressure glaucoma derived from high myopia or glaucoma is considered to be the first stage feature of visual acuity, and the visual function slightly decreases along the optic nerve axon running etc. Failure to detect the region in detail.
The conventional perimeter cannot detect in detail the position shape of the visual field area where the visual function is slightly degraded, so that the visual field characteristics peculiar to advanced myopic normal tension glaucoma can be compared with the retinal structure such as optic nerve axon running , It may not be detected.
Since the conventional perimeter cannot detect in detail the position shape of the visual field region in which the visual function is slightly deteriorated, there is a possibility that detection of glaucoma visual field characteristics in the initial stage has failed.
Conventional perimeters have a low resolution examination, and the target used for the examination does not have the ability to sensitively detect areas with slightly reduced visual function. It is impossible to detect in detail the position and shape of the visual field area where the visual function is slightly deteriorated, which is considered to be a characteristic feature of pressure glaucoma or glaucoma.
A conventional perimeter cannot detect glaucoma characteristics at a very early stage.
When the static visual target and perimeter program of the present invention according to claim 156 is used, it becomes possible to detect a region where the visual function is slightly lowered in the subject's visual field, and its position and shape are detailed on the display. It becomes possible to display.
When the perimetry program of the present invention is used to move the static target of the present invention in a horizontal direction successively at regular intervals every time a target recognition response by a subject is used, not only a blind spot but also a normal target It is possible to intuitively display in detail an area where the visual function that cannot be detected is slightly deteriorated on the display.
In fact, the phenomenon in which the static target of the present invention according to claim 156 is not recognized within the visual function degradation region of the subject visual field, or is visually recognized from the static target of the present invention according to claim 156. The phenomenon that the movement is not recognized but is recognized statically in the visual function deterioration region occurs.
The static visual target of the present invention according to claim 156 can detect glaucoma characteristics at a considerably initial stage.
The perimeter program of the present invention makes it possible to display the glaucomatous visual field characteristics at a very initial stage on the display in such a detail as to remind the running of the optic nerve axon.   According to the static target of the present invention and the perimeter program according to claim 157, a general computer having a slow display drawing processing speed is changed to a perimeter that is sensitive enough to detect even a region where the visual function is slightly lowered. try to. According to the present invention of claim 156, in order to give the static target used in the visual field inspection program the ability to detect a slight decrease in visual function, for example, blinking at high speed and high frequency while looking at paper or the like. If it does, it will try to utilize the phenomenon in which the visual field part which has deteriorated the visual function is recognized as a dark, low luminosity region with respect to other visual fields.
When a subject who has an area with a slightly reduced visual function in his visual field blinks at a high speed and high frequency, he can recognize such an area clearly and darkly with respect to other parts of the visual field. When applied, for example, if a static target with red-orange display can be blinked on a display with a black background color at high speed and high frequency blinks, the red-orange color is equivalent to the visual function degradation visual field area. There is a possibility that a phenomenon that can be perceived darkly and visually occurs.
The red-orange static visual target flashes at high speed and with high frequency blinks within the visual field area where visual function is reduced by adjusting the luminosity or luminosity density of the red-orange static visual target. There is a possibility that a phenomenon in which visual recognition is not performed due to a decrease in visual luminosity or visual recognition becomes difficult may occur.
From such a point of view, the present invention provides a very small red-orange target at the tip position of the radius, which is very short but not displayed, centering on the position where the target should be presented under the black display background color. One is placed, one red-orange target is placed at the position where the radius is twice that length, and the two red-orange targets are quantized around the position where the target should be presented. A static target for detecting a visual function deterioration region that can be used even by a general computer by a method of circular trajectory at high speed.   The invention according to claim 156 provides a very small red-orange target at the tip position of the radius, which is very short but not displayed, centered on the position where the target should be presented under the black display background color. One is placed, one red-orange target is placed at the position where the radius is twice that length, and the two red-orange targets are quantized around the position where the target should be presented. A static target for detecting a visual function deterioration region that can be used even by a general computer by a method of circular trajectory at high speed. Quantum high speed means that the circular velocity that can be realized for a red-orange target is too slow at the display drawing processing speed of a general computer, so the angular velocity is set to 26.6 ° when determining the circular orbit coordinates of a red-orange target. This is a method of increasing the central angle considerably discontinuous.
In the case of the static visual target of the present invention according to claim 156, for example, degreez = .degreez + 26.6 is set.
The diameter of the circular orbit corresponds to the size of the static visual target.
When the presentation density with respect to time of the red-orange target at any position on the circular orbit approximates high-speed and high-frequency blinks, the recognition of the static target of the present invention according to claim 156 has little effect on the visual function. It is considered that a phenomenon that becomes difficult in a region where a significant decrease occurs compared to other fields of view. According to the present invention, in order to give the static target used in the visual field inspection program according to the present invention the detection capability for a slight decrease in the visual function, for example, while looking at paper or the like, When the eyes are used, the visual field portion that has deteriorated in visual function tends to be recognized as a dark, low-luminosity region with respect to other visual fields.
When a subject who has an area with a slightly reduced visual function in his visual field blinks at a high speed and high frequency, he can recognize such an area clearly and darkly with respect to other parts of the visual field. When applied, for example, if a static target with red-orange display can be blinked on a display with a black background color at high speed and high frequency blinks, the red-orange color is equivalent to the visual function degradation visual field area. There is a possibility that a phenomenon that can be perceived darkly and visually occurs.
The red-orange static visual target flashes at high speed and with high frequency blinks within the visual field area where visual function is reduced by adjusting the luminosity or luminosity density of the red-orange static visual target. There is a possibility that a phenomenon in which visual recognition is not performed due to a decrease in visual luminosity or visual recognition becomes difficult may occur.

The diameter of the circular orbit corresponds to the size of the static visual target.
When the presentation density of the red-orange target at any position on the circular orbit approximates high-speed and high-frequency blinks, recognition of the static target of the present invention causes a slight decrease in visual function. In some areas, it is considered that a more difficult phenomenon occurs than in other fields of view.   When the static visual target of the present invention and the perimeter program of the present invention according to claim 157 are used, it is possible to detect a region where the visual function is slightly lowered in the subject visual field, and the position shape is displayed on the display. It becomes possible to display in detail.   157.
