12000 degrees myopia true existence?Huaxi Ophthalmology experts say extremely rare

The Weibo entry of "I am myopia 12000 degrees" was rushed to the hot search on September 20, which caused heated discussion among netizens. Such high myopia glasses lenses are indeed different from ordinary lenses. There are multiple layers of circles in the center and decreased in order.

Many netizens marvel at this degree "beyond common sense", and also deeply worried about their deepening myopia. Ma Wei, a lecturer, lecturer Ma Wei, a lecturer of adolescents from the Ophthalmology Department of Huaxi Tianfu Hospital, Sichuan University, said that the 12,000 -degree ultra -high myopia is very rare in clinical, generally genetic, genes, genes Mutations are related. According to Ma Wei, she has not encountered myopia more than 10,000 degrees in clinical work, or even 8000 degrees. In daily life, the most height is more than 1,000 degrees of high myopia. Therefore, the number of myopia is 12,000 degrees, which should be extremely rare cases.

High myopia patients are usually accompanied by the extension of the axis. The normally eye axis is 24 mm, the number of myopia increases by 300 degrees, and the eye shaft increases by 1 mm. Based on 12000 degrees, the eye shaft is about 60 millimeters. The eyeballs above centimeters are also rare. "According to doctors, the ultra -altitude is often accompanied by genetic mutations or genetic history.

Moreover, for patients with ultra -high myopia, even if they wear frame glasses, contact lenses, or some eye conditions, they often cannot achieve normal vision. "In vision disorders, the correction of the vision is less than 0.3, which is a low vision category, and the correction of the vision is less than 0.05, which is defined as blind." Ma Wei explained that this is all vision disability.

Myopia is related to heredity and environment.

According to Ma Weimi, the Eye Department of Huaxi Tianfu Hospital of Sichuan University, the super height of more than 1,000 degrees, or even three or five thousand, is not only caused by eye habits, often accompanied by factors such as genetic mutations and high myopia family genetic history. In addition, for adults, the degree of myopia is relatively stable. As long as there is no disease factors, the possibility of a significant increase in the number of myopia in a short period of time is small. However, children of academic age, because of their daily eye habits, are unhygienic, they will increase rapidly in a short period of time. "In the past, there were many junior high school students who came to the doctor and were paired with glasses, and later developed to the senior grade of primary school students. Now there are many cases of myopia in primary schools." Ma Wei said that according to 2018, from 2018, it has been screened from Chengdu primary and secondary schools. Statistics show that the myopia rate of primary school students is about 40%, about 70%of junior high school students, and about 80%of high school students. I attach great importance to it, and I have made a lot of efforts, so the growth rate has slowed down. "

Therefore, children should not forget the old rules: hold a pen tip of the pen, a fist from the table, and one foot from the eyes.

In addition, it is worthy of paying special attention to the myopia that causes myopia, the number of myopia is too high, the eye axis increases too long, and the risk of underground disease will increase, such as retinal macular lesions, retinal detachment, vitreous turbidity, etc. The risk of super high myopia, the risk of white internal and glaucoma. Therefore, it is also important to do regular medical examinations for myopia.
