There is no fixed number of times after which intraocular injection of anti-VEGF drugs for macular degeneration can be cured. Generally, multiple treatments are needed, one injection per month for three months. If you want to improve your vision, the common injection protocol is to give one injection every month, three times, and then go back for a review. After these three injections, the doctor will go through OCT and imaging to assess whether your condition is stable. If the disease is stabilized after these three injections, you can stop taking them for the time being, but you have to follow up strictly, because the disease may come back again after a while, and if it comes back, you have to take the injections again. Sometimes there is no relapse, but there is still some oozing fluid, so it is necessary to inject again for insurance purposes. Because the standard treatment plan is 3 injections in a row, domestic use is also more often when the disease worsens, the effect is a little bit worse but also good. Macular degeneration keeps developing, and it turns the whole macular area into a scar. As long as the lesion is active, it should be stopped. If there is active leakage, edema, and subretinal fluid accumulation, the macular scar will extend and increase in size to the surrounding tissues. A macular scarring is when the patient really misses the time to treat it, or it is not treated. If the disease is stabilized and no fluid continues to seep out it can be temporarily eliminated. Stopping the medication on your own may lead to a relapse of the disease and some patients may experience a sudden loss of vision. Vision is slowly decreasing and cannot be used to judge the severity of the disease or to evaluate whether the disease is progressing, stabilizing or improving; it cannot be relied upon. The purpose of treatment is to improve visual acuity, but the effect of treatment cannot be judged by the improvement of visual acuity. Sometimes the patient exudes a lot, because the exudate, or hemorrhage at once arches the retina very high, this inside the fluid accumulation is a lot, can not effectively reach the local treatment concentration, at this time on the injection of three shots will not work, but also must continue to play down. Another problem is PCV – polypoid choroidal vasculopathy, a disease that responds poorly to photodynamic and intraocular injections. If an Oriental has this disease, the eye bleeds and oozes quite a bit, and it is not as well treated with either of these methods as it is with age-related macular degeneration. A significant number of patients feel improved visual results after the injection. Domestic and foreign studies have found that 60%-70% of patients’ vision can be stabilized, and about 30% of patients’ vision can be improved by more than two to three lines, so the effect is still very good. However, there are some patients who do not respond to the injection.
