Abstract: the abnormal nutritional metabolism in myopia changes the capsular permeability of the lens, and the lens is gradually turbid due to nutritional and metabolic disorders, resulting in concurrent cataract. This cataract develops slowly, mainly with core opacity and posterior capsular opacity, and the visual acuity decreases gradually., The occurrence of myopia is affected by many factors. Although the exact pathogenesis is still being explored, it is definitely related to genetic factors and video equipment in modern society, close learning, high work pressure, failure to pay attention to eye hygiene, incorrect fitting glasses and wearing inferior glasses. With the gradual increase of myopia, it will not only cause the decline of far vision, but also many complications, and may lead to permanent visual impairment., So, what ophthalmic diseases will myopia be complicated with?, 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 is prone to perforation. Some have perforated to form dry holes. In addition, vitreous liquefaction and increased mobility lead to detachment of the traction retina. Two thirds of retinal detachment cases are myopia., Cataract, myopia, abnormal intraocular nutrition metabolism, changes the capsular permeability of the lens, lens dystrophy and metabolic disorder, and gradually turbidity, resulting in concurrent cataract. This cataract develops slowly, mainly with core opacity and posterior capsular opacity, and the visual acuity decreases gradually., Macular hemorrhage and macular degeneration, myopic eye dilation, poor eye blood supply, retinal ischemia, the retina produces a kind of neovascular growth factor, which makes the subretinal neovascularization grow.

With the gradual increase of myopia, it will not only cause the decline of far vision, but also many complications, and may lead to permanent visual damage.
so, what ophthalmic diseases will myopia be complicated with?
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 is prone to perforation. Some have perforated to form dry holes. In addition, vitreous liquefaction and increased mobility lead to detachment of the traction retina. Two thirds of retinal detachment cases are myopia.
cataract
myopia has abnormal intraocular nutrition metabolism, which changes the capsular permeability of the lens, gradually produces turbidity due to lens nutritional disorder and metabolic disorder, and produces concurrent cataract. This kind of cataract develops slowly, mainly core opacity and posterior capsular opacity, and the visual acuity decreases gradually.
macular hemorrhage and macular degeneration
myopic eyes have dilated eyeballs, poor eye blood supply and retinal ischemia. The retina produces a kind of neovascular growth factor. These factors make subretinal neovascularization grow. These neovascularization tubes are very easy to rupture and bleed, and form macular hemorrhage after bleeding. After multiple bleeding, local scars are formed, and macular degeneration will permanently damage vision.
vitreous liquefaction denaturation
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 and turbidity, causing dark shadow in front of the eyes and inducing retinal detachment.
glaucoma
the structure of the filter curtain at the atrial angle of myopia is abnormal, so the outflow resistance of aqueous humor in the eye is large, which is easy to cause the increase of intraocular pressure, but it is difficult to measure accurately. According to statistics, one third of high myopia has glaucoma, which will gradually lose vision.
strabismus and amblyopia
myopia can cause exotropia or exotropia. For example, if the difference of myopia degree between the two eyes is greater than 300 degrees, it is easy to cause exotropia with deep degree and posterior staphyloma of amblyopia
myopia
posterior staphyloma is formed due to the continuous growth of eye axis and the posterior pole of sclera, Then it causes choroid cell retinal atrophy.
