高度近视对人体最大的危害是什么 许家骏 北京中医药大学东直门医院 高度近视它对人体的最大的危害就是它黄斑出现问题，尤其我们常说是高度近视，黄斑出血了，这只是我们给你说的一个症状。它的诊断名词应该叫病理性高度近视，黄斑区的新生血管。那这个是因为高度近视引起的，我们大家都知道我们正常人的眼轴是24，也就是从角膜一直到眼底这个距离。眼轴的长度是24，如果你是一个近视，那你这24就变得长了，也许26、27。如果你要是300度近视或400度近视，可能就27这个眼轴的长度。如果你要眼轴达到了30毫米，那这时候你就高度近视，这就是说眼球拉长了。那眼球拉长了就给我们提出一个叫物体的力学的改变，就跟我们一个房子一样。房子得有顶柱，这时候房子它结构才稳定，那高度近视因为眼轴拉长，那物体的力学改变首先改变的最关键的一步就是我们的黄斑区。 What is the biggest harm of high myopia to human body The biggest harm of high myopia to human body is the problem of its macula, Especially we often say that it is high myopia, The macula is bleeding, It's just a symptom we told you. Its diagnostic term should be pathological high myopia, Neovascularization in the macular region. That's because of high myopia, We all know that our normal eye axis is 24, That is, the distance from the cornea to the fundus. The length of the eye axis is 24, If you are a nearsighted person, Then you're 24 years old, Maybe 26, 27. If you are 300 or 400 degrees nearsighted, Maybe the length of the eye axis is 27. If you want the eye axis to reach 30 mm, At that time, you will be highly myopic, This means that the eyeballs are elongated. When the eyeball is lengthened, it gives us a mechanical change called an object, Just like one of our houses. A house has to have a roof post, At this time, the structure of the house is stable, The high myopia is due to the elongated axis of the eye, The first key step of the mechanical change of the object is our macular area.
