High myopia refers to the degree of myopia above 600 degrees, and from ordinary myopia to high myopia is not only a deeper degree but also a qualitative change.
The axis of normal vision is generally about 24 mm, while the axis of high myopia is generally more than 26 mm. The human eye is a sphere, and you can think of it as a balloon, and the bigger the balloon becomes, the thinner the balloon wall becomes. Our retina is a transparent film attached to the inner wall of the eyeball, and as the eyeball gets longer and longer, the retina will be pulled thinner and thinner, and there is a risk of retinal detachment if you are not careful.
Therefore, people with high myopia must try to avoid behaviors that give strong shocks to the eyes and head. For example, it is often heard in the news that lying in bed and playing with a mobile phone, and it is very dangerous for the mobile phone to fall and hit the eyes. There are also sports with a fierce sense of ** such as bungee jumping, and combat sports with fierce confrontation such as boxing sanda, the impact is very large, so it is best not to touch it.
There are many other complications of high myopia, such as vitreous opacity, vitreous hemorrhage, leopard fundus, retinal hemorrhage, macular hemorrhage, etc., some of which refer to fundus lesions. It is particularly susceptible to severe vision loss and even blindness.
Huizhou Mingkang Eye Hospital warmly reminds: friends with high myopia must change their bad eye Xi to prevent myopia from deepening.
