First of all, many people know “macular pre-membrane”, but this is actually the real scientific name. Let’s analyze it. The word “idiopathic” means that we do not know the cause of the disease, and many diseases cannot be found, so we have the word “idiopathic” to summarize it. Let’s look at the “retinal anterior membrane”, in fact, the retina is the negative of the eye, and the membrane can be long on this film, but what you are most concerned about is the “macula” which is a small place, because it is the place that affects your vision the most. I can tell you about it next time. Another point to emphasize is that the macula is a part of the retina or a structure of the eye, and many people always say “Doctor, I have the macula! This is a mistake, just like no one says “Doctor, I’m sick, I have a nose”. One of the questions that many patients ask is “How did I get this disease?” . The truth is that doctors don’t know either. This one shows you a lot of causes, but they are all possibilities, so you can take a closer look if you can find the same ones as you. Nevertheless, aging is recognized as the most likely cause, and this cause is not avoidable by anyone. That’s why I often suggest in my clinic that those elderly people who are not satisfied with their vision, check macular OCT. If you’ve never had it checked before and you’re over 60 years old, go to the hospital and check OCT. ”A membrane grows inside the eye”. It sounds quite scary, and many people think that this membrane will definitely cover their eyes and make them blind. In fact, this membrane is very small when it first grows out, and in most cases it grows very slowly and transparent when it first comes out, so most people don’t feel anything and only find it when they have macular OCT. However, in a small percentage of people, the membrane will slowly become thicker and less transparent, so it is not difficult to understand the loss of vision. The annoying thing is that this membrane will also shrink, just like these little people are constantly tugging and pulling your macula, so it slowly becomes more and more wrinkled, and when the force is so big that the whole retina is involved, seeing things will be distorted, which means the disease has been a long time! The macula is divided into 3 levels. In fact, the vast majority of patients in the clinic are grade 0, they do not feel anything, but OCT examination found, because this level is generally very stable, long-term unchanged so often do not do any treatment. But the next two stages are different, as soon as they enter grade 1, the nature of the membrane is different, because the membrane component tends to fibrosis, the contraction begins, the two pictures above are the fundus photos of the same patient at different times, the one below do you feel that the blood vessels are stretched and distorted? Theoretically at this level it can be treated surgically. Often the patient hears a different voice, i.e., “don’t operate, keep watching”. Why is this? First of all, this stage of the patient’s vision is often very good, or more blurred, this time surgery, patients do not want to operate, and will not feel improved after surgery; Secondly, macular surgery on the surgeon’s requirements are very high, in the medical considered a special surgery, and also in recent years by the doctor’s understanding, so many ophthalmologists do not understand, not the fundus surgery doctors often do not recommend the patient surgery; Finally, the patient in the doctor’s guidance. Finally, patients are closely followed up under the guidance of their doctors, and often gradually realize that their vision is indeed declining constantly, and their willingness to operate will be very strong, and this is the best time for surgical intervention. However, there are still patients who are afraid and repeatedly cannot decide, so they delay surgery and have poor vision recovery. In outpatient clinics, patients often ask their doctors, “How far will my vision recover after surgery?” As a professional ophthalmologist, it is impossible to guarantee the prognosis to any patient, and even if the doctor knows that he can determine it, he cannot tell you exactly, considering the severe doctor-patient relationship nowadays, so there is no need to ask this question again and again in the future. However, doctors will often tell you the results of some studies that indirectly answer this question. This table lists many items that affect the recovery of vision after surgery. Different colors represent different degrees, red means there must be a relationship; orange means possible; purple means no; so the doctor at the top of the list will answer, “It is recommended to operate earlier, even if you don’t do it now, you should observe it closely and operate in time if there is a bad one. The earlier the surgery, the better the recovery of vision. As to how far you recover, it varies from person to person.” There are several points to emphasize about macular surgery: 1, this kind of surgery is completely feasible, the key is to find a professional fundus surgeon; 2, the surgery is in the macular area, which naturally determines its big risk, but overall speaking, it is still safe; 3, there is a possibility of vision loss for patients in the early stage after the surgery; 4, the recovery of vision from macular surgery generally takes 6-12 months; 5, the earlier the surgery, the better.
