There is no cure for diabetic retinopathy. But laser treatment (photocoagulation) is usually very effective at preventing vision loss if it is done before the retina has been severely damaged. Surgical removal of the vitreous gel (vitrectomy) may also help improve vision if the retina has not been severely damaged.
Diabetic retinopathy can cause vision loss in two ways: 1  Macular Edema. 2  Macular edema is a condition where your retinal blood vessels develop tiny leaks. 3  When this occurs, blood and fluid leak from the retinal blood vessels and fatty material (called exudate) is deposited in the retina.
