How can vision be restored after vitrectomy

The recovery of vision after vitrectomy depends on its primary disease, such as retinal detachment, fundus hemorrhage, diabetic retinopathy, central vein occlusion, intraocular tumor, the most fundamental determinant is whether these diseases affect the retina macula. Macula is equivalent to the heart of the human body, which is the most important place for vision. If it does not affect the macula, vision recovery is normal; but once it affects the macula or macula, vision will be affected to some extent. If it affects the macula, it depends on factors such as the length of the onset. The onset time is relatively short, it is possible that vision can be restored to the original, and vision will be affected for a long time. For example, retinal detachment, once the range of detachment affects the macula for more than a week, the possibility of the final corrected vision reaching 0.3 is only about 30%.
