Abstract: high myopia and its harm. If the degree of myopia exceeds 600 degrees or the length of ocular axis exceeds 26 mm, it is called high myopia. In addition to high diopter, high myopia is also accompanied by pathological changes of fundus, which is an important cause of blindness.
according to statistics, among the 400 million myopia patients in China, the proportion of high myopia patients has reached 35%, and it is still rising gradually. More than 300000 people have been blinded by high myopia in China, and China has become a serious disaster area of high myopia.
high myopia and its harm. If the degree of myopia exceeds 600 degrees or the length of ocular axis exceeds 26 mm, it is called high myopia. In addition to high diopter, high myopia is also accompanied by pathological changes of fundus, which is an important cause of blindness. In some patients with high myopia, the myopia diopter and axial length will continue to increase in their life, which not only affects their vision, but also prone to complications such as glaucoma, cataract, macular neovascularization, retinal splitting, retinal detachment and so on. If you have high myopia since childhood and do not have timely, correct and effective treatment, it is likely to lead to amblyopia, strabismus and so on.
high myopia heredity high myopia has certain heredity, which has been recognized by everyone. Over the years, genetic studies have proved that the vast majority of high myopia is autosomal recessive. People with this kind of myopia are often very young, and the degree of myopia is very deep. Many people’s parents are also highly myopic. Although high myopia has a certain relationship with heredity, it is not absolute. There are two main reasons for high myopia.
on the one hand, the degree of myopia increases year by year and develops into high myopia because ordinary myopia does not choose appropriate glasses or does not pay attention to eye hygiene. This kind of myopia is generally below -10.00d, without heredity, also known as acquired high myopia. Another reason for
is that parents have high myopia or have high myopia gene, and their children have high myopia gene or high myopia after birth. This myopia is closely related to heredity.
