Myopia degree can constantly deepen for two reasons: Generally speaking, children’s myopia may increase by 50 ~ 75 degrees in one or two years.The myopia degree of adult have an increase of 50 to 75 degrees two or three years,which is common situation. There are usually two causes of deepening myopic degree.One is pathological myopia, which is internal lesions inside eyes, inherited, and you can see this kind of myopia grows rapidly and continues to deepen. If myopia is increased by more than 100 degrees,even up to 200 degrees or higher within one year,or the total degree reaches 2000 degrees, it is likely for pathological myopia.
There is not sound cure method for sacroiliac myopia nowadays. If posterior scleral grape swollen is formed, the treatment could be posterior scleral reinforcement. A wide fascial strip is used to hold the posterior sclera in this operation. On one hand,it strengthens the support force of posterior sclera, preventing the continuous development of posterior scleral staphyloma.

If you are the first time to optometry, mydriasis test is also needed. At the same time, to conduct a detailed fundus examination to rule out retinal disease and conditions such as crystal defects. Take care the eye-sanitation: for my part, it is important to save the time to use our eyes. Because the human eyes are in the growth and development period, looking at the near is limited, if consumption exceeded the limit,it may occur pathological changes,thus occurs myopia.
