Retinal detachment is simply the detachment of the retina from the wall of the eye to which it is attached. It is usually sudden and has some causative factors. The most important sensation after retinal detachment is the appearance of a black shadow in front of the eyes, the size of which depends on the extent of the detachment and may gradually become larger. If the macula is not detached, the central vision may not be affected or may be mildly reduced, but if the macula is detached, the central vision will definitely be reduced. Therefore, some people’s vision is not affected by retinal detachment and some people’s vision is greatly affected. Macula is the most sensitive part of human retina, if the macular area is involved for too long after retinal detachment, even if the retina is reset in anatomical sense through surgery, the loss of photoreceptor function of visual cells is still irrecoverable. Therefore, it is very important to consult and confirm the diagnosis in time after the vision is found to be affected! Surgery is not a cure for all diseases, and the recurrence rate after surgery is relatively high, but there is nothing anyone can do if the time to save the disease is missed. The prognosis is not good in most cases of multiple surgeries, combined with high myopia, glaucoma, optic nerve disorders or other eye pathologies; generally speaking, the biggest goal of surgery is to save the remaining vision and the eye.
