Abstract: the treatment of high myopia should start with the expansion of posterior sclera. After more than ten years of efforts, scleral reinforcement can be used to prevent the development of high myopia because the eyeball becomes longer and larger, myopia does not develop, pathological damage stops, protect the existing vision and thicken the eyeball wall.
causes of myopia
from the natural course of high myopia, genetic and environmental factors lead to posterior scleral expansion and posterior scleral staphyloma. Posterior scleral expansion can cause two changes: the first is the extension of ocular axis and the increase of myopia diopter; In addition, it can also lead to retinal choroidal expansion, resulting in a series of diseases, such as extramacular lesions and macular lesions. The key reason of myopia caused by
is that the eyeball becomes longer and larger. The first is that the intraocular focus is not on the retina, but in a certain part of the eyeball in front of the retina, which forms myopia in refraction; Another problem is more serious. After the eyeball becomes longer and larger, the eyeball wall becomes thinner, the firmness is reduced, the blood vessels are reduced, the nutritional metabolism is impaired, the retinal function is damaged, resulting in the decline of visual function, and there will be complications leading to blindness.
thinking on the treatment strategy of high myopia
it can be seen that the treatment of high myopia should start with the expansion of posterior sclera. After more than ten years of efforts, scleral reinforcement can be used to prevent the development of high myopia by protecting the existing vision and thickening the eye wall. Posterior scleral reinforcement can treat fundus diseases, such as macular hole, splitting, detachment, simple bleeding, choroidal neovascularization and atrophy. The application of posterior scleral reinforcement in
can prevent the occurrence and development of fundus lesions; Stabilize the eye axis, slow down the growth of diopter, shorten the eye axis and reduce the diopter, so as to prevent the development of high myopia. The therapeutic mechanism of
for macular detachment of high myopia to explore the therapeutic mechanism of
for macular detachment of high myopia. Genetic and environmental factors can lead to posterior scleral expansion (posterior scleral staphyloma and axial extension), posterior scleral expansion can lead to a series of macular complications, such as macular hole, splitting and detachment; if vitrectomy, oil injection and gas injection are adopted, the macula is pressed and forcibly reset, so that the posterior scleral expansion can not be controlled and the macular expansion continues to aggravate, it can lead to a series of complications, such as silicone oil eye, cataract and secondary cyanosis Eyes, the formation of holes, leading to macular and fundus atrophy, take oil, it is easy to relapse. The posterior scleral reinforcement can lift the macula, shorten the eye axis, limit the expansion of the posterior sclera, so as to loosen the expansion of the macula and make the macula separate and reset.
comprehensive treatment process of high myopia
for high myopia, the treatment measures that can be taken include refractive correction, such as glasses and refractive surgery; Treatment of fundus lesions and complications, such as drug and surgical treatment; Control the progress of high myopia, wear corneal shaping glasses, sanitary eyes, and posterior scleral reinforcement.
