Diabetic Retinopathy is the most common diabetic eye disease. Diabetic retinopathy usually affects both eyes. People who have diabetic retinopathy often do not notice changes in their vision in the disease's early stages, but as it progresses, diabetic retinopathy usually causes vision loss that in many cases cannot be reversed. Nonproliferative diabetic retinopathy (NPDR) is the earliest stage of diabetic retinopathy. With this condition, damaged blood vessels in the retina begin to leak extra fluid and small amounts of blood into the eye. Sometimes, deposits of cholesterol or other fats from the blood may leak into the retina. Proliferative diabetic retinopathy mainly occurs when many of the blood vessels in the retina close, preventing blood flow. In an attempt to supply blood, the retina responds by growing new blood vessels, however these new blood vessels are abnormal and do not supply the retina with proper blood flow.
