Is eye myopia degree too high can cause blindness?

Can eye myopia degree too high cause blindness? Myopia eyesight drops, see far not clear and see near clear. Long time close work or reading, will occur as fatigue phenomenon, feel heavy eyelids, eye swelling headache, nausea, dry eyes, etc.

In high myopia above 600 degrees, the axis of the eye is obviously elongated, resulting in posterior scleral staphyloma, a series of pathological changes, and even retinal detachment and blindness. Because the anterior and posterior diameter of the eyeball in high myopia keeps growing and becomes a long ellipse. Due to the backward expansion of sclera, the choroid around the optic nerve papilla atrophies, forming a half moon shaped myopic arc spot on the temporal side of the optic nerve papilla, and further developing into a circular arc spot. A series of diseases also occur in the fundus. The retina and choroid diffuse atrophy, and the retina becomes fragile and thin, especially in the eyes Retinal degeneration, atrophy, macular hemorrhage and formation of black spots in the posterior pole and macular region,

Serious damage to vision. Vitreous opacification liquefaction, can appear part of the concentration and point, strip or flocculent turbidity, with eye movement and up and down floating, often and retina adhesion, traction retina and split hole, liquefied vitreous through the split into the retina, leading to retinal detachment. The retina is where the visual cells are located, and the visual cells are the special receptors to receive light stimulation. After the onset of retinal detachment, the retina will lose the source of nutrition, and the visual cells will gradually shrink, thus losing vision.

After reading the above content, we should have some understanding of the problem of blindness caused by too high myopia. Today we will introduce here. More topics about eye health will be introduced in the following chapters. Welcome to check. I wish you a happy life!
