Blindness is undoubtedly the most frightening of all eye problems, but many blinding eye diseases can be avoided. Today, let Dean Li Yong talk to us about the blinding eye disease - macular degeneration.
The pathological mechanism of macular degeneration is mainly the aging change of macular structure. It is manifested by the decreased phagocytosis and digestion function of retinal pigment epithelial cells on the outer disc membrane of optic cells, so that the undigested disc membrane remnants are stored in the basal cell plasma and discharged to the outside of the cell, forming drusenous warts. Therefore, the occurrence of macular degeneration after secondary pathological changes is mainly related to long-term chronic photodamage in the macular area, choroidal vascular sclerosis, and aging of retinal pigment epithelial cells.
Everything looks crooked, it turns out that macular degeneration is making trouble.
1. What do you know about age-related macular degeneration?
Age-related macular degeneration, also known as age-related macular degeneration, is one of the most important blinding eye diseases worldwide. Most of the patients are over 50 years old.
As we said before, the macula is the visual center of the retina, and we can see everything by the macula. Therefore, once there is a problem with the macula, it will naturally cause damage to vision.
Therefore, friends over the age of fifty or sixty need to pay special attention to their eyesight.
2. Macular degeneration performance**?
Macular degeneration is more common in the elderly and is an age-related degenerative eye disease, and there is no effective way to ** macular degeneration. Macular degeneration is divided into wet and dry, wet macular degeneration clinical manifestations of severe visual impairment in the center, some only peripheral vision remains, and the fundus shows macular hemorrhage, and after bleeding absorption, it leaves irregular scars. Dry macular degeneration is manifested as drusen in the macular area, which can cause varying degrees of damage to vision. Because the macular of the lesion cannot be completely regenerated, it cannot be ** after macular degeneration.
3. How to prevent age-related macular degeneration?
1. Ultraviolet rays or some other harmful rays can also damage the macula, so if you go to places with strong ultraviolet rays such as plateaus, it is recommended to protect your eyes.
2. Pay attention to a balanced diet, eat more vegetables and fruits, eat less too greasy food, and maintain the habit of exercise is good for the whole body.
4. How to identify whether you have macular degeneration?
Macular degeneration is a chronic process, and patients often do not feel particularly obvious symptoms in their eyes, such as redness, pain, itching, etc., and its manifestations are mostly more recessive vision slowly declining, blurring, etc.
If you feel that you are getting bigger and smaller when you read words, or if the doors and windows are deformed, you need to check whether you have macular degeneration and go to the hospital for examination as soon as possible.
Dean Li Yong reminded that although the worse results of macular degeneration may lead to blindness, if it is detected early, it can be controlled.
