Compared with those with normal vision or low myopia degree, the axial length of high myopia is longer, and the longer the axial length, the higher the myopia degree. The ocular axis refers to the anterior and posterior axis of the eyeball, which is similar to the diameter of the eyeball. The longer the diameter is, the thinner the eyeball wall is. After the retina on the eyeball wall becomes thinner, the probability of retinal degeneration, tear, detachment, subretinal neovascularization and posterior scleral staphyloma is higher, which will lead to the decrease of eyesight and even blindness.
In addition, the age of cataract in high myopia may be earlier than that of normal vision, and the probability of glaucoma is higher than that of normal vision. Cataract is one of the main eye diseases leading to blindness, and blindness caused by glaucoma can not be recovered at present.
