Whether vision can be restored after retinal detachment surgery is related to the extent of retinal detachment, time, whether the macula is involved, and the timing of surgery. 1. Extent of detachment The larger the extent of retinal detachment, the greater the impact on vision. When the total retinal detachment is more than 2 years old, even if the patient’s retina is restored by surgery, it is difficult to improve the vision after surgery. 2. Time of detachment This is mainly for patients whose retinal detachment involves the macula. The longer the macular detachment lasts, the worse the vision recovery. If the detachment lasts more than 1 month, the final visual acuity will not be more than 0.3, and if the detachment lasts more than 3 months, the visual acuity will hardly reach 0.1 after the operation. 3. Whether the detachment involves the macula Whether the macula is detached or not will largely determine the recovery of visual function after surgery. Once macular detachment occurs, it is very difficult to recover vision completely. 4. Timing of surgery The shorter the duration of retinal detachment, the earlier the surgical treatment, the better the postoperative visual recovery may be, especially if the surgery is performed before macular involvement, the better the result will be. 5. Other Elderly people with retinal detachment have slower improvement in postoperative vision; postoperative vision changes in patients with silicone oil placement are related to whether or not they follow the doctor’s instructions to perform postural maneuvers such as lowering the head and lying down. Whether the vision of retinal detachment patients can be restored or not is related to many factors, patients should go to regular hospitals in time, and choose the appropriate treatment plan under the guidance of doctors to improve the quality of life.
