Abstract: high myopia, that is, ametropia with myopia greater than 600 degrees. In addition, children with myopia greater than 400 degrees are considered high myopia. At this time, this kind of myopia is equivalent to pathological myopia or degenerative myopia. The cause of high myopia is not very clear. But it has a lot to do with heredity. The acquired environment will also act on the incidence of myopia., Now myopia tends to be younger, especially high myopia, which can not be ignored. Many children have put on glasses at a young age due to heavy schoolwork and the influence of modern electronic technology products, and many are still high myopia, which is undoubtedly a great blow to patients. Wearing eyes for a long time will not only deform their eyes, Some children even feel inferior, so they should pay attention to it., So how to judge whether it is high myopia? From the five symptoms of high myopia., 1. Fundus changes., Arc spots can be clearly seen next to the optic papilla. In addition, the omentum is highly leopard shaped, and omental atrophy spots also appear. At this time, the macula begins to degenerate., 2. Exophthalmos: in patients with high myopia, the anterior diameter and posterior diameter of the eyeball increase significantly. Some patients will have retroscleral staphyloma, accompanied by symptoms such as deepening of the anterior chamber and ciliary muscle atrophy. In some patients, exophthalmos is obvious., 3. Dark shadow appears in front of eyes: due to vitreous degeneration, liquefaction and other symptoms in high myopia, there are turbidity and floating objects in the glass. At this time, the patient will have flying mosquitoes, spark spots and flashes.,
now myopia tends to be younger and younger, especially high myopia, which can not be ignored. Many children have put on glasses at a young age due to heavy schoolwork and the influence of modern electronic technology products, and many are still high myopia, which is undoubtedly a great blow to patients. Wearing eyes for a long time will not only deform their eyes, Some children even feel inferior, so they should pay attention to it.
so how to judge whether it is high myopia? We look at the five symptoms of high myopia.
1. Fundus changes. Arc spots can be clearly seen next to the optic papilla of
and
. In addition, the omentum is highly leopard shaped, and omental atrophy spots also appear. At this time, the macula begins to degenerate.
2. Exophthalmos: Patients with high myopia of
have obvious growth of anterior and posterior diameter of eyeball. Some patients will have posterior scleral staphyloma, accompanied by symptoms such as deepening of anterior chamber and ciliary muscle atrophy, and some people have obvious exophthalmos.
3. There is a dark shadow in front of the eyes:
high myopia. Due to vitreous degeneration, liquefaction and other symptoms, there are turbidity and floating objects in the glass. At this time, the patient will have flying mosquitoes, sparks and flashes.
4. Vision loss:
high myopia will bring many complications, such as cataract, macular hemorrhage, and vision loss. The most serious one is retinal detachment, even blindness and eye atrophy.
5. Myopia develops rapidly:
high myopia often develops rapidly in childhood and reaches another peak in adolescence; In addition, some high myopia will continue to develop in adulthood, that is, progressive myopia.
therefore, patients must protect their eyes at ordinary times, which can be adjusted by doing eye exercises, maintaining correct sitting posture and visual distance, and eating more vegetables and fruits rich in vitamin A at ordinary times. In addition, you should look at the distance every 30 minutes to avoid visual fatigue; Don’t open your eyes when you wake up in the morning, rub your eyes with your thumb, and then look at your eyes in four directions. In addition, doctors suggest that patients with high myopia should go to the hospital for examination every six months to one year, so as to take intervention measures at an early stage. To sum up,
and
are some introductions to judge high myopia, hoping to be helpful to readers. As we all know, high myopia has great harm and many complications. Therefore, once myopia is found, it must be treated and controlled in time. In daily life, we should also pay attention to eye hygiene, do more eye exercises, and get enough rest for the eyes to get the best effect.
