When people reach the age of middle and old age, they always can't escape the eyes of the physical examination report, not only some small problems occur in various parts of the body, but also our various organs begin to age and get sick. For example, mothers and mothers-in-law at home will find themselves looking at things, and there is always a black shadow in front of them, or the straight lines they see suddenly become bent, and even they always see things vaguely every day, because they are older? Or is it because of an eye disease? Is it presbyopia? In fact, it may not be at all, it is caused by macular degeneration in the fundus!
In fact, everyone has a macula, and the macula is the most acute and delicate area of vision on the retina, and the "macula" that everyone often talks about mostly refers to macular degeneration. Among them, the most common is age-related macular degeneration.
Age-related macular degeneration is a degenerative fundus disease that can lead to severe vision loss and is one of the leading causes of blindness in people aged 50 years and older.
What is "age-related macular degeneration"?
The "macula" is a normal physiological structure located in the center of the retina of the fundus, which is an oval-shaped slightly sunken area, which is called macula because it is rich in yellow pigment, and is the most critical and special area of our fundus. It may be a bit obscure, but when we look at the eye chart, we look at the central vision of the macula, and once there is a lesion in that area, the central vision will be severely affected.
For example, macular hole will occur, because with age, the vitreous gradually liquefies, and the fixation effect on the retina becomes smaller, especially the separation of the back of the vitreous from the retina, which can easily lead to the occurrence of macular hole.
What are the causes of macular holes?
In addition to aging, there are 5 key triggers for macular holes:
High myopia. Trauma to the eyeball.
Retinal degeneration.
Long-term cystoid macular edema.
vitreous traction, etc.
In the early stages of macular holes, there may be no discomfort in our eyes, or there may be a slight decrease in vision. However, with the development of the disease, the vision will decline significantly, and then slowly it will evolve into irreparable fatal damage, this disease is indeed difficult, but we can prevent it as soon as possible, so that the eyes are in a healthy state as much as possible!
Two or three methods of prevention for the eyes
Avoid prolonged exposure to radiation.
It is recommended that you do not stay outdoors for a long time and avoid long-term light radiation, which will cause damage to the eye lens, and when you go out to play, you should take some protective measures, and it is best to wear a hat or sunglasses.
Care should be taken to avoid eye strain.
When working and studying, it is recommended to learn to arrange time reasonably, and also leave a gap for the eyes to rest.
Perform eye exercises on a daily basis.
It is necessary to pay attention to reasonable eye massage, such as massaging the temples to help promote blood circulation, and pay attention to maintaining a good attitude to avoid causing poor qi and blood, which will affect the eyes.
