Description
Technical Field
The embodiment of the invention relates to the technical field of ophthalmic surgical treatment tools, in particular to a posterior sclera quantitative pressurizing block and a use method thereof.
Background
With the remarkable increase of the prevalence rate of high myopia in China in recent years, epidemiological researches indicate that the number of patients with high myopia is 2900 to 3040 ten thousand, and fundus lesions caused by high myopia become one of important diseases of irreversible blindness. The traction maculopathy caused by the high myopia mainly comprises three types of macula fovea retinal cleavage, macula fovea retinal detachment and macula fovea cleavage holes, and is a group of blindness-causing diseases which seriously affect the visual function of patients.
There are several currently mainstream options for the clinical treatment of traction maculopathy, including maculoexoplasty (macularbuckle), vitrectomy (PARSPLANA VITRECTOMY, PPV) and vitrectomy in combination with maculopathy, the purpose and key of which are to relieve traction of various factors on the retina and restore normal anatomy and physiological function of the macula. The macular outer pressurization helps to relieve the posterior scleral grape swelling from pulling on the outer retina (anteroposterior direction), shortens the path required for retinal replacement, and avoids possible damage to retinal function by the inner eye surgery. Vitrectomy is mainly a pars plana vitrectomy combined with an inner limiting membrane stripping operation, and is used for removing tissues (tangential direction) with traction on the macula part, and simultaneously removing a framework structure of pathological proliferation of cells, so that the possibility of recurrence of the macula anterior membrane is reduced. It is believed by researchers that vitreous surgery can provide anatomic reduction and improved function of high myopia traction maculopathy. In addition, there are reports in the literature that analysis of a large number of samples demonstrates that retromacular scleral stiffening can provide patients with a higher retinal reduction rate.
Since the eyeball of a patient with high myopia is often changed in anatomy, the eye is characterized by the growth of an eye axis, irregular eyeball shape and posterior scleral grape swelling, and the overall morphology of the eye is found to be approximately divided into 4 main types of sphere, cone, bowl and column according to the result of a 3D-MRI eyeball model. However, the external pressure implant used in the conventional macular external pad pressing operation at present cannot completely coincide with the shape of an eyeball, which increases the operation difficulty, so complications such as iatrogenic damage to retina, sclera, extraocular muscle and the like easily occur in the operation, and symptoms such as exposure infection, strabismus, deformation of vision, astigmatism and the like may also occur due to poor fit of the external pressure implant after the operation. At present, quantitative jacking cannot be realized by all scleral external compression implants.
