Clinically, myopia degrees are generally classified into four grades:
Myopia of less than 300 degrees is considered mild
Myopia ranging from 300 to 600 degrees is considered moderateMyopia over 600 degrees is considered high myopia
Myopia above 1000 degrees is considered extremely high myopia
In life, the myopia degree of most people is within 1,000 degrees. There are only a very small number of people whose myopia degree exceeds 1,000 degrees, and even reaches 2,000 degrees or higher. There is no definite upper limit to the degree of myopia, but as the degree of myopia increases, the risk of retinal lesions and vision impairment faced by patients will also increase significantly.
In addition, high myopia may also induce glaucoma, cataracts and other eye diseases, all of which may lead to blindness.
3.How can complications of high myopia be avoided?
The probability of developing eye diseases for people with high myopia is several times that of normal people. However, the vision loss and blindness caused by high myopia can be avoided:
1）. Regular check-ups and early treatment. People with myopia of over 600 degrees, especially middle-aged and elderly patients with high myopia, are advised to have their fundus examined once a year. If you notice any abnormal vision, distorted vision, visual field obstruction, or a large number of floaters, you must seek medical attention as soon as possible.
2）. Be careful when doing vigorous exercise. The eyes of people with high myopia are more fragile. Therefore, any sports that might hit the eyeball should be avoided as much as possible, such as boxing, diving, football, basketball, etc. One should also be cautious about recreational activities such as roller coasters and bungee jumping that may cause a sudden increase in intraocular pressure.
