50-year-old Ms. Chen, early is a myopic patient, now, her myopia has reached 1200 degrees, wearing glasses all year round has become her habit. Recently, Ms. Chen after the square dance, feel wear glasses also can not see things clearly, had to go to the hospital for examination, the hospital examination results surprised her! ” What? Retinal detachment? ” Ms. Chen is very confused: considering that they are highly myopic, usually rarely use electronic products, eyes have not suffered any trauma, what happened? But in the end, in order to restore vision, Ms. Chen had to undergo surgery. The retina is prone to detachment after strenuous exercise. In this regard, experts say that usually, the structure of the eye of highly myopic people will change because of long-term myopia, such as the gradual expansion of the eye to become larger and longer, with the expansion of the sclera of the outer wall of the eye, the retina will be stretched thinner and thinner. In layman’s terms, a thinner retina is like a piece of clothing that is worn thin and tears easily, especially during strenuous exercise, when the liquefied vitreous humor moves and pulls on the weak retina, resulting in a “hole” in the retina, through which fluid from the eye can This is when the fluid in the eye pours in through the “hole” and causes the retina to detach. Two symptoms to be alerted to Today, more and more people are highly myopic, and the number of patients suffering from retinal detachment has also increased. Due to the lack of knowledge about eye care in some people, in the early stage of the disease, and will not choose to seek medical attention in a timely manner, to the onset of the disease, has reached an advanced stage of the disease, had to undergo surgery. At present, retinal detachment is mainly divided into primary, foramen ovale, traction, exudative, etc. The most common primary retinal detachment is found in highly myopic and middle-aged people, which is because, with age, small liquefaction cavities begin to appear in the central part of the vitreous of middle-aged people, and then the liquefaction range expands, coupled with the presence of retinal deformation, atrophy, thinning, etc. in elderly myopic patients. At this time, when these patients do some shaking head and other movements, it may lead to the liquefied vitreous pulling retinal detachment. If patients feel intermittent flashing sensation in their eyes, or black shadows floating in front of their eyes, or even black shadows blocking in a certain direction, they should go to the hospital for detailed examination as soon as possible. This is because these may be early signs of retinal detachment. After retinal detachment, even after surgery, vision recovery is relatively difficult, so she suggested that such patients should regularly go to the ophthalmology department to check the fundus, if the eye is found to exist in the degenerative zone or retinal fissure, then you can do early treatment, and thus prevent “net off”. Prevention: Three aspects of eye protection 1. Try to take care of your eyes in daily life, do not read books, TV, computers, etc. for a long time. During the period, but also pay attention to the correct posture of the eyes, such as lying down to read, walking while reading, and reading books and computer screens too close to the incorrect posture, may cause visual fatigue, long-term may lead to myopia, and thus lay a hidden danger for the retinal detachment; 2, for myopic patients, especially with high myopia (adults with myopia greater than 600 degrees, children with myopia greater than 400 degrees of Refractive error), should be in daily life, avoid too strenuous sports, such as playing basketball, horseback riding, diving, boxing, fast running, etc.; 3, in the diet, according to the actual situation of individuals, should eat more carrots, pig liver, etc., these foods are good for the eyes.
