Diabetic retinopathy, or diabetic eye disease, refers to a group of eye problems that people with diabetes may face as a complication of diabetes. All can cause severe vision loss or even blindness. It is caused by changes in the blood vessels of the retina.
During the first three stages of diabetic retinopathy, no treatment is needed, unless you have macular edema. To prevent progression of diabetic retinopathy, people with diabetes should control their levels of blood sugar, blood pressure, and blood cholesterol.
Proliferative retinopathy is treated with laser surgery. This procedure is called scatter laser treatment. Scatter laser treatment helps to shrink the abnormal blood vessels and works better before the fragile, new blood vessels have started to bleed. Scatter laser treatment may slightly reduce your color vision and night vision.
