Friends with myopia above 600 degrees should be careful! Otherwise

Abstract: high myopia, also known as malignant myopia, degenerative myopia and pathological myopia, generally refers to ametropia with myopia degree greater than 600 degrees, accompanied by ocular axis extension, fundus degeneration and visual dysfunction.

a friend with myopia of 600 degrees hurried here, looked nervous and gasped out of breath. “It’s over! I had a fundus examination today. I said it was leopard shaped fundus. What do you mean, is it serious? Will it be blind…”

first defined this anxious friend as a group with high myopia.

high myopia, also known as malignant myopia, degenerative myopia and pathological myopia, generally refers to ametropia with myopia degree greater than 600 degrees, accompanied by ocular axis extension, fundus degeneration and visual dysfunction. A series of pathological changes of eye tissues often occur in people with high myopia due to eye axis extension and posterior pole expansion: Leopard shaped fundus, myopic arc spot, posterior scleral staphyloma, lacquer crack, Fuchs spot, macular hemorrhage, subretinal neovascularization and lattice or cystic degeneration around the retina. Therefore, high myopia not only means that the degree of myopia is high, but also the risk of fundus lesions is higher than that of normal people.

leopard shaped fundus, god horse Dongdong?

I believe everyone knows that after the balloon is blown up, the color of the balloon will be relatively lighter and the exposure of internal objects will be clearer, right? The eyeball is the same. Due to the extension of the ocular axis and the expansion of the eyeball, the eyeball wall tissue becomes thinner. Firstly, the retinal pigment epithelium becomes thinner and straightened after leaving the optic disc. In addition, the changes of choroidal capillaries cause nutritional disorders in the retinal pigment epithelium, resulting in the reduction or disappearance of shallow pigment. In this way, the brown pigment between the exposed choroidal red blood vessels and the vascular network staggered to form the characteristic fundus change of myopia – “leopard shaped fundus”, especially in the later pole. The longer the ocular axis, the higher the degree of myopia and the older the age, the more obvious the leopard shaped fundus.

leopard shaped fundus, is it serious?

and

strictly speaking, “leopard shaped fundus” belongs to non pathological fundus changes. It can be regarded as a superficial phenomenon of high myopia, similar to facial redness as a superficial symptom of fever. However, it is a very important sign – indicating the upcoming pathological fundus lesions that will cause visual dysfunction. As a pre pathological change marker with special clinical significance, controlling the different stages of leopard like changes can prevent or slow down the evolution and occurrence of pathological changes.

therefore, people with high myopia should pay particular attention to regular fundus examination. If leopard shaped fundus is found, the examination frequency should be increased, and corresponding measures should be taken to avoid serious decline of visual function or even blindness.
