Abstract: because there are many complications of high myopia, some complications need to be treated in time, and some complications such as retinal degeneration and holes need preventive laser treatment to prevent blindness. The prevalence of
high myopia is very high, about 1%. High myopia can cause many serious complications, most of which will cause blindness. It is one of the common causes of blindness in adults, accounting for the sixth place in blinding diseases in China. The main complications of
. Complication 1: posterior scleral staphyloma: the incidence was 77.1%. The main manifestations were posterior expansion of the posterior pole of the eyeball, degeneration and atrophy of the optic nerve and perimacular retina, and decreased corrected visual acuity. The higher the degree of myopia, the higher the incidence of posterior scleral staphyloma. Complications of
: retinal atrophy, degeneration, hemorrhage and hole: due to factors such as lengthening of ocular axis and posterior scleral staphyloma, patients with high myopia are prone to retinal degeneration and hole, resulting in hemorrhage and retinal detachment, leading to blindness.
complication 3: subretinal neovascularization: the incidence is 5% – 40%. It is manifested as subretinal neovascularization in the posterior pole, causing bleeding and affecting vision.
complication 4: retinal detachment, cataract and glaucoma: due to scleral expansion and retinal degeneration, the chance of retinal detachment in patients with high myopia is 7-8 times higher than those without high myopia. The chance of high myopia complicated with cataract and glaucoma is also higher than that of normal people.
have many complications due to high myopia, some complications need to be treated in time, and some complications such as retinal degeneration and holes need preventive laser treatment to prevent blindness. Therefore, patients with high myopia should often check the fundus and intraocular pressure, so as to achieve early detection and early treatment.
