Abstract: the structure of the filter curtain at the atrial angle of myopia is abnormal, so the outflow resistance of aqueous humor is large, which is easy to cause the increase of intraocular pressure. According to statistics, 30% of high myopia have glaucoma, which will cause the gradual loss of vision., Myopia can cause many eye complications, most of which are blinding. The higher the degree of myopia, the greater the possibility of complications. These complications are: 1. Retinal detachment is the most common complication of myopia. Due to axial elongation and intraocular dystrophy in myopia, cystic degeneration and lattice degeneration often occur around the retina. The retina in the degenerative area is very thin and prone to perforation. Some have been perforated and formed in sexual holes. In addition, vitreous liquefaction and increased mobility lead to retinal detachment. 70% of retinal detachment is myopia., 2。 Cataractous myopia has abnormal intraocular nutrition metabolism, which changes the capsular permeability of the lens, gradually produces turbidity due to lens dystrophy and metabolic disorder, and gradually reduces visual acuity, resulting in concurrent cataract. This cataract develops slowly, mainly with core opacity and posterior capsular opacity., 3。 Macular hemorrhage and macular degeneration myopia have poor ocular blood supply and retinal ischemia. The retina produces a kind of neovascular growth factor. These factors make the subretinal neovascularization grow. The tube wall of these neovascularization is very thin and easy to rupture and bleed. Macular hemorrhage is formed after bleeding. After the bleeding is absorbed, the new blood vessels can rupture and bleed again. After multiple bleeding, short marks are formed locally, causing macular degeneration, which permanently damages vision., 4。 Vitreous liquefaction and degeneration vitreous is colorless and transparent jelly. When the eyeball of myopia increases, the vitreous body will not increase again, so the vitreous body can not fill all the space in the eye, resulting in liquefaction, increased mobility and turbidity, causing dark shadow in front of the eyes and inducing retinal detachment., 5。 The filter curtain structure at the angle of glaucoma and myopia is abnormal, so the outflow resistance of aqueous humor is large, which is easy to cause the increase of intraocular pressure. According to statistics, 30% of high myopia have glaucoma, which will cause the gradual loss of vision., 6。 Strabismus, amblyopia and myopia can cause exotropia or exotropia. If the difference between the degrees of myopia in both eyes is greater than 300 degrees, it is easy to cause deep exotropia and amblyopia.,
myopia can cause many eye complications, most of which are blinding. The higher the degree of myopia, the greater the possibility of complications. These complications are:
1. Retinal detachment is the most common complication of myopia. Due to axial elongation and intraocular dystrophy in myopia, cystic degeneration and lattice degeneration often occur around the retina. The retina in the degenerative area is very thin and prone to perforation. Some have been perforated and formed in sexual holes. In addition, vitreous liquefaction and increased mobility lead to retinal detachment. In retinal detachment, 70% are myopia.
2。 Cataractous myopia has abnormal intraocular nutrition metabolism, which changes the capsular permeability of the lens, gradually produces turbidity due to lens dystrophy and metabolic disorder, and gradually reduces visual acuity, resulting in concurrent cataract. This kind of cataract develops slowly, mainly core opacity and posterior capsule opacity.
3。 Macular hemorrhage and macular degeneration myopia have poor ocular blood supply and retinal ischemia. The retina produces a kind of neovascular growth factor. These factors make the subretinal neovascularization grow. The tube wall of these neovascularization is very thin and easy to rupture and bleed. Macular hemorrhage is formed after bleeding. After the bleeding is absorbed, the new blood vessels can rupture and bleed again. After multiple bleeding, short marks are formed locally, causing macular degeneration, which permanently damages vision.
4。 Vitreous liquefaction and degeneration vitreous is colorless and transparent jelly. When the eyeball of myopia increases, the vitreous body will not increase again, so the vitreous body can not fill all the space in the eye, resulting in liquefaction, increased mobility and turbidity, causing dark shadow in front of the eyes and inducing retinal detachment.
