What symptom does retinal atrophy have?

summary

We all know that the retina is very important for our eyes. It is the object image establishment point of our eyes. If our retina shrinks, it may have a greater impact on our health. In order to avoid this situation, let's talk about the symptoms of retinal atrophy?.

What symptom does retinal atrophy have?

First, there are two types of photoreceptors: rod cells and cone cells. Rod cells were mainly distributed around the retina, which was used for dark vision; Cone cells are located in the central area of the retina, which can be seen by sming. Retinal atrophy, retinal atrophy refers to a variety of lesions caused by damage to the retina, retinal atrophy, need to find out the cause of atrophy, remove the cause of disease as soon as possible, to prevent further decline in vision. Some optic atrophy is caused by genetic factors.

Second, animal experiments show that the central fovea of the retina can not be stimulated clearly, which easily leads to a sharp increase in the axial length of the developing animals, and then the formation of high myopia. High myopia is often accompanied by pathological changes (such as macular degeneration, vitreous opacity, floater's disease, posterior scleral staphyloma, retinal detachment, posterior lens surface opacity, etc.).

Third: generally, myopia caused by long-term and long-term nearsightedness is simple myopia. Now it is considered that it is inherited by multiple factors. It is not only subject to genetic laws, but also affected by environmental factors. Generally, it does not continue to develop in adulthood. If it is not prevented, it may become high myopia, If we don't pay attention to it (for example, we should wear corrective glasses instead of using them), the pathological changes will be deepened; However, the myopia caused by heredity is generally called pathological myopia. There is evidence that high myopia in China is autosomal recessive heredity. Now there is no good way to control it. High myopia often forms and continues to develop in adulthood. In addition to genetic factors, myopia is caused by close eye use.

matters needing attention

So we suggest that we should know how much damage retinal atrophy does to our health. We treat retinal atrophy in our life through surgery, and we should pay attention to our diet in our life.
