Unfortunately, this is true. Myopia, it seems nothing more than to become the family of glasses, the visual will become clear. But in fact, far more than myopic refractive errors so simple to solve. Myopia, especially above 300 degrees of high myopia, retinal thinning often in strenuous exercise, moving heavy objects, when in collision, it might cause their retinal detachment, and even lead to blindness.
Retinal detachment means between pathological changes of the retina and retinal pigment porous layer membrane separation cortex. According to retinal detachment range is divided into partial and complete two types, according to their etiology is divided into primary and secondary categories. Retinal detachment is the separation of the epithelium and retinal pigment epithelium between. Retinal detachment part does not work, the brain accepts images from the eye to all incomplete or missing. Retinal detachment retinal detachment is divided into primary and secondary retinal detachment, primary retinal detachment is a common clinical disease, patients with more men than women about 3: 2, the majority of adults over the age of 30, 10 years of age rare in children, the difference between right and left eyes, eyes incidence rate is about 15% of patients. Prone to myopia. Especially high myopia.
More common in patients with early symptoms of retinal detachment is the first front will move in the shadows of sense, if there is a flash point, or the like to fly some of the symptoms, do not to rub the eyes, but also not suitable for strenuous exercise. Eye drops can not be used indiscriminately, if the vision decline as soon as possible should go to a professional eye hospital for examination, retinal detachment because if more than 7 days, even if the surgery will not be restored to the previous vision.
Diving is a sport that people love to watch, but retinal damage diver became the most prominent of all types of injury problems, and even to be known diver "occupational disease." Diving champion Guo Jingjing in 1996 there have been cases of retinal detachment, her visual acuity was only 0.2. On the eve of the Beijing Olympic Games, Guo Jingjing eye relapse, but eventually Guo Jingjing to overcome difficulties and win the gold medal, after retirement, she successfully passed into surgery to repair the retina.
In addition to diving, the other equally strenuous exercise may cause retinal detachment. High myopia of the eye itself is already very fragile. Their eye axial length, thin wall of the eye, the retina also will become fragile, and even damage the retina itself may exist at this time, if external force is very vulnerable to injuries. Therefore, prevention of retinal detachment, there is a high degree of myopia is best not to strenuous exercise.
But do not be too nervous, high myopia is not on all the sports can not do. Due to high myopia easily lead to retinal detachment, should be avoided could result in head or eye motion activities. Some doctors also recommend avoiding eye pressure will lead to an increase of activities, such as scuba diving, skydiving.
According to a medical website, not because of a detached retina eyes closed, body bent, weight changes. Therefore, weightlifting seems okay. However, two recent studies found that some articles from lifting weights (especially with the Valsalva action) lead to retinal detachment or macular case, there is one study weightlifting ocular blood pressure. Some myopic focus on recent case studies found that using weightlifting Valsalva action would lead to increased likelihood of retinal detachment.
Some doctors recommend avoiding doing activities with sudden acceleration and deceleration, as this will increase the pressure of the eye, such as bungee jumping, drag racing, roller coaster and so on. In addition, appropriate additional movement is still relatively safe, of course, no matter what sport, high myopia should pay particular attention to the protection of the eyes during movement.
On the other hand, some retinal detachment can be prevented. The most effective method is found in the posterior vitreous detachment omen can pay attention to timely medical treatment. Early detection can be found in the retina tear, and laser or cryotherapy treatment. This reduces the risk of retinal detachment, the risk from 1: 3 to 1:20 reduction.
