China is a country with a high prevalence of myopia. Among the 300 million myopic patients in China, there are more than 10 million patients with high myopia, and the trend is increasing year by year, and the prevalence rate of Chinese college students is as high as 20%. High myopia is called pathological myopia when the myopia increases year by year, the eye axis lengthens, and a series of corresponding fundus lesions appear. Pathological myopia is extremely dangerous and is one of the leading blindness-causing eye diseases. Common pathological myopia fundus lesions include: posterior scleral staphyloma, retinal choroidal atrophy, macular hemorrhage, macular anterior membrane, macular cleft, macular fissure, retinal detachment, etc. Myopia is the most common eye disease and is divided into three categories according to the degree of myopia: 1, mild myopia: the degree of myopia is less than 300 degrees. 2, moderate myopia: the degree between 300 degrees – 600 degrees. 3. High myopia: above 600 degrees or more. There is no particularly effective clinical intervention for the prevention of pathological myopia, and posterior scleral reinforcement is the only treatment for the lengthening of the eye axis, which has certain efficacy, but the long-term effect is still under observation; for the treatment of late stage fundus complications of pathological myopia, most of them can be treated by surgery, but whether the final vision can be preserved and restored depends on the degree of damage of the fundus lesion.
