Myopia is more than blindness. How many complications do you know?

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 complications include:

retinal detachment

the most common high myopia complications. As the ocular axis becomes longer, the posterior half of the eyeball becomes thinner, the retina and choroid atrophy and degeneration, resulting in split space, causing bleeding and retinal detachment with different ranges, resulting in visual loss. In retinal detachment, 70% are myopia.

and

macular hemorrhage and macular degeneration

and

myopia have elongated eye axis, resulting in poor blood supply and retinal ischemia. In order to ensure blood supply, neovascularization will be generated. The tube wall of these neovascularization is very thin and easy to rupture and bleed, resulting in macular hemorrhage. After the bleeding is absorbed, the new blood vessels may rupture and bleed again. In this way, repeated for many times, local scars will form and cause macular degeneration, which 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, increased mobility 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. According to statistics, 30% of high myopia have glaucoma, which will cause the gradual loss of vision.

strabismus and amblyopia

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.
