With advances in medical technology, the vast majority of retinal detachments are treatable. Depending on the type of retinal detachment, the extent of the detachment, and the duration of the detachment, the treatment varies. And the final vision of the patient varies. The most common type of retinal detachment is a foraminal retinal detachment due to a fissure in the retina, which must be surgically closed. In the case of traumatic retinal detachment, spontaneous retinal detachment due to high myopia, retractive retinal detachment due to fundus hemorrhage and vitreous hemorrhage, the retina must be surgically repositioned by intraocular pneumatization, vitrectomy, and injection of silicone oil or heavy water. In exudative retinal detachment, no fissure appears, but the retina is detached due to other ocular diseases, so the main focus is on treating the primary disease and surgery is usually not required. When a retinal detachment is treated and reset, it is a return of the anatomical position, which does not mean that the visual function will be similarly restored to the pre-detachment level. This is because the photoreceptor cells of the retina, during the pathological process of detachment, undergo irreversible death. If the detachment is small and does not involve the macula, and if the detachment is short, better vision can be restored after surgery. Therefore, the only way to expect to be able to restore the best possible vision is to make a timely diagnosis, cooperate with treatment, and allow the retina to be reset in the shortest possible time.
