Abstract
A contrast sensitivity module for restoring the visual function of amblyopia patient is composed of an examine model and a training model. The contrast sensitivity information between the visual target to be measured and the reference target in models as biologic information can stimulate the human brain to restore the visual function.
Description
Technical field
The present invention relates to a kind of sign stimulus that utilizes and repair the damaged contrast sensitivity module of amblyepia vision function.
Background technology
It is undesired that the feature of amblyopia shows as following spatial vision function: contrast sensitivity function, vernier vision and space visual deterioration, the interaction of abnormal space, the damage of profile identification, binocular visual function undesired, the damage of binocular visual acuity, eyes integration function undesired or the like.Wherein, contrast sensitivity belongs to the rudimentary visual function of visual system.
The Vision information processing process of visual system is stratified.At first, eyes are perceived light wave, transform (frequency conversion) by the different spatial integration stages then, and each stage all forms complicated more acceptance domain.Substantially, spatial integration is divided into three phases.With " E " sighting target on the observation visual acuity chart is example, and first stage is that contrast is distinguished, distinguishing on background exactly has the not existence of sighting target; Second stage is sample analysis, exactly each feature of sighting target extracted separately; Three phases is that these features more than all are integrated.An important image analysis stage is arranged in primary visual cortex, and it is very sensitive to the contrast of the image of different directions, different scales, and forms some unique information acceptance domains.Human contrast sensitivity is exactly the sum total reaction of these individualities.
Each individual cells is (interference) that alters a great deal to the reaction of the same stimulus object of continuous appearance.For single cortical neuron, interference may discovering and distinguishing very big restriction is arranged sighting target.And these neuronic interactions have determined the contrast sensitivity under the different space frequency, and their activity combination has determined the function of each contrast sensitivity.Brain can be concentrated all neuronic reactions, and gets the meansigma methods of each neuronic interfering activity, so just can improve signal to noise ratio, and visual performance is had facilitation.A lot of researchs show that all by the suitable selection to the visual stimuli state, the interference of each cortical cell can both be controlled.The scientists utilization can effectively activate and be matched with the Gabor sighting target of acceptance domain shape in the visual cortex, makes the low-level contrast sensitivity of adult obtain 2 times raising.
Studies show that the space interaction between the direction acceptance domain has important function for adjusting these corresponding neural individual activities.In certain specific region, the contrast sensitivity of image can play the effect that strengthens or weaken according to the regional in its vicinity distribution of light.That is to say, respectively add a moderate high-contrast object of reference (on the same straight line) in position on the sighting target both sides and can promote the contrast of directivity sighting target to distinguish.
The specific training of this visual task is " perception study " (perceptual learning).It can improve visual performance greatly.Discover: patient's neural side direction suppresses to strengthen alternately, particularly for the sensation target of high spatial frequency.Neural vision is rescued technology by target training arranged side by side in the same way, the mutual inhibition of the neural side direction of the reduction that obtains helps to improve patient's contrast sensitive function, reverse and grow the growth infringement that causes in " plastic " phase in early days, reach treatment amblyopia patient's effect.
So-called neural vision is rescued, and the side direction interaction technique with peripheral vision is applied to dysopia's treatment exactly.The science background and the principle of this technology are:
When seeing object, the people can be influenced by other object.
Gabor sighting target in the same way can promote or suppress the gabor sighting target in the central foveal vision, and the best distance of promotion is 2-3 λ (λ is wave period).
The people that central foveal vision is damaged uses the peripheral retina thing, and for peripheral retina, they only see low spatial frequency.
If with the gabor sighting target of central foveal vision low spatial frequency, effect is not very big.
Of the present invention open
The objective of the invention is to utilize the neural vision of contrast sensitivity to rescue and set up the damaged bio information reparation of a kind of effective amblyepia vision function module, brain function based on the people has plasticity, with training the amblyopia patient being bestowed suitable bio information by the detection of science stimulates, and finally reaches the repair damaged to amblyopia patient's visual function.
The objective of the invention is to reach like this: a kind of amblyepia vision function is repaired module, comprises detection model and training pattern.The initial orders of module are detection model, and system will be transformed into training pattern automatically afterwards, and acquiescence training rank is the 9th grade.System can respectively arrange in the both sides of sighting target to be measured at random one identical with sighting target to be measured with reference to sighting target, so repetition training is distinguished for the contrast of directivity sighting target with training for promotion person.
The present invention has following advantage compared to existing technology: the present invention is based on present visual perception bio information in the world and handles on the basis of the newest fruits of studying, and sets up the damaged bio information of a kind of novel visual function and repairs module.Only determine that with the visual acuity chart vision sufferer visual function compares with existing, the present invention combines the damaged inspection of special visual performance with special training, and perfect visual information system reparation module is overlapped in formation one; This brand-new theoretical pattern has been represented the scientific idea in international forward position, and be that species specific, a personalized visual function is repaired module, the state that main contrast sensitivity to the amblyopia patient is handled module is judged, and is improved patient's contrast sensitive function pointedly.
The drawing explanation
Fig. 1 is a detection model sketch map of the present invention.
Fig. 2 is a training pattern sketch map of the present invention.
1. with reference to sighting target, sighting target 2. to be measured is 3. trained rank, 4. training time.
Embodiments of the present invention
With reference to Fig. 1, in detection model, 1 meter of detected person's range display when at every turn detecting, eyes are parallel with display, and when image flicker, the detected person judges whether the center, interface has sighting target 2 to be measured to manifest.Sighting target 2 to be measured and all manifest at random with reference to sighting target 1.
With reference to Fig. 2, in training pattern, 1 meter of trainer's range display, eyes are parallel with display, and when image flicker, the trainer judges whether the center, interface has sighting target 2 to be measured to manifest.Sighting target 2 to be measured and all manifest at random with reference to sighting target 1.Initial training rank 3 is the 9th grade, answers questions continuously to rise 1 grade for 3 times, promotion to 15 grade; Whenever answer mistake and once fall 1 grade, minimumly reduce to 1 grade.Each training time 4 was controlled at about 10 minutes.
