Retinal detachment is a relatively rare disease in ophthalmology, but retinal detachment is a very dangerous disease that can cause blindness if not treated urgently, and therefore it is one of the major blinding diseases in China. Retinal detachment mainly occurs in people with myopia, especially in middle-aged and middle-aged patients with high myopia, while myopia occurs mostly in intellectuals, so blindness due to retinal detachment is the main blindness-causing disease among intellectuals in China! For patients with retinal detachment, the vast majority of patients require surgical treatment. With the advancement of medical technology, the success rate of surgery for retinal detachment is still very high, and the success rate of surgery in our hospital is over 90%. Although the success rate of surgery is greatly improved, we found that there are still a considerable number of patients who have poor post-operative vision recovery and do not achieve the purpose of detachment, the main reason is that they were not admitted to the hospital early for surgery! As the key of vision recovery after retinal detachment surgery is whether the retinal detachment involves the macula before surgery, that is, whether the macula is detached and the time of detachment, a large number of clinical statistics show that if the macula is not detached before surgery, then the vision after surgery can basically recover to the condition before retinal detachment occurred, if the time of macular detachment is less than one week, then the vision can also recover to a better level, but if Even if the surgery is successful and the retina is no longer detached, the patient still cannot see after the surgery and becomes blind, which is quite a pity. Therefore, in foreign countries, patients with retinal detachment are treated as emergency patients, because not many hospitals in China are competent to carry out retinal detachment surgery, mainly in the eye centers of large hospitals in major cities, but the beds in these large hospitals are quite tight, most of them can not carry out emergency surgery to save the patient’s vision, and wait in line for a week or two or even longer to notify the admission to the hospital for surgery, surgery Although the surgery is successful, the patient is still blind after the surgery.
