Q: Why does myopia cause retinal detachment? Ophthalmologist: Simply put, after myopia, our eye axis will become longer, and the retina, which was originally designed for healthy eyes, will also be stretched, so it will be a bit “untenable”. In general, we can only see a small part of the retina through the pupil during a physical examination, but after the retina is stretched, a horseshoe-shaped fissure can easily appear, which cannot be detected without a dilated fundus check, and this may cause retinal detachment. Therefore, I believe that no matter you are young, middle-aged or old, as long as you are nearsighted, you are at high risk of retinal detachment and need to have a detailed fundus examination with dilated pupils. Internet users ask: Why do some people wear glasses for a lifetime without retinal detachment? Ophthalmologist: That’s right, but the chances of finding a fissure are high for this group of people who have dilated pupils and are just lucky not to have detached. Of course, there are some people who have worn glasses for a lifetime without retinal fissures and are very healthy. These people are more physically fit and have a healthier lifestyle, and have not done excessive exercise or physical labor. Netizen Q: Are there any characteristics of patients with retinal detachment caused by myopia, such as their occupation, or gender and age? How should I prevent it? Ophthalmologist: If you are nearsighted and engaged in physical labor, then you are at high risk in the high-risk group. In fact, we can’t say that people sitting in the office are not at risk. We all know that people sitting in the office now have long contact time with computers every day and are prone to overuse their eyes, especially those who often work overtime and stay up late, which is very bad for the eyes. To prevent retinal detachment, from the first point, we must be careful to “use the strength”, such as young people to move things to the strength of the line; older friends to buy things in the morning market, do not carry too heavy. There are also dry stool people also pay attention to the toilet when not too hard. The second point is to prevent trauma, we should pay attention to protect our eyes in life, our ophthalmologist will never rub our eyes hard because these are very dangerous actions. The third point is to keep a happy mood. Netizen Q: What are the early symptoms of retinal fissure and retinal detachment caused by myopia? Ophthalmologist: If you feel blurred vision and vision loss you can come to the hospital for examination. Early retinal detachment will have flying mosquitoes, that is, there are black shadows floating in front of the eyes; some people will appear in front of the flash; serious may suddenly black piece in front of the eyes, like this fixed black shadow obscuration is almost already off. In general, this situation must be promptly consulted. Netizen Q: What are the current treatment options for retinal detachment? Ophthalmologist: Once the retina is detected to have a fissure, we will use laser repair. Retinal detachment retinal repair surgery is the largest and most complicated surgery in ophthalmic surgery. 90% of patients can have a successful surgery, while a small number of patients with complex conditions need multiple surgeries. Netizen Q: What should I pay attention to after surgery? Ophthalmologist: The initial period after retinal detachment surgery also requires more bed rest. Patients who have undergone vitrectomy and filled with silicone oil should make their heads lie down to avoid shock, so as not to affect the effect of surgery; pay attention not to rub the operated eye, so as not to cause infection and inflammation of the operated eye. During the recovery period, in addition to using medications as prescribed, eat nutritious and easily digestible food to promote recovery; eat more fruits and vegetables to prevent constipation, wine, irritating and hard food should not be eaten; avoid sewage flowing into the eye when washing hair; exercise in moderation, do not overexert yourself, do not dive and dive, avoid picking up things and carrying heavy objects with your head down. In addition, you should also follow up regularly according to medical advice.
