Why is high myopia very dangerous?

Once it exceeds 600 degrees, it is highly myopic.

However, when the axis of high myopia is elongated, the outermost membrane of the eye-sclera (white eye) will be stretched, pulling the retina and choroid inside, leading to thinning and ischemia. Therefore, there are many fundus problems-retinal tear and detachment, abnormal choroidal neovascularization, bleeding, leakage and macular edema, which will lead to decreased vision and serious damage to eye health. That is, it has evolved into "pathological myopia."

Pathological myopia is not a static disease.

The macula of the fundus (the most sensitive part of vision) will gradually degenerate, leading to decreased vision; More seriously, about 5%- 10% people may have complications of choroidal neovascularization, which will eventually lead to retinal detachment and fall from light to darkness in an instant.

Therefore, people with high myopia should go to the hospital for eye examination as soon as the following situations occur!

The degree of myopia increases rapidly, and the vision drops sharply.

It is easier to get tired than ordinary people, and can't see things clearly for a long time, which may be accompanied by eye pain, headache and nausea.

There are shadows fluttering in front of us, with various shapes, such as dust, line and ring. , occasionally accompanied by a flash in front of my eyes.

If there is no discomfort, people with high myopia also need to have a fundus examination every six months.

How to prevent it? It's a cliche that some people find it hard to do it!

1) Avoid using eyes at close range, especially reduce the excessive use of electronic equipment, and pay attention to eye rest, which will alleviate and improve eye fatigue.

2) You can usually eat more fresh fruits and vegetables with more vitamins A, B, C, D and E, and properly supplement lutein to enhance macular function.

3) Outdoor sports are not suitable for strenuous sports such as football, basketball and diving. You can choose gentle ways such as jogging and mountain climbing to prevent violent impact and avoid lifting heavy objects.

4) Strengthen the awareness of prevention and treatment of high myopia, and go to the hospital for fundus examination regularly.
