Diabetes Home > Information on Diabetic Retinopathy

A leading cause of blindness, diabetic retinopathy occurs when diabetes damages the tiny blood vessels inside the retina, the light-sensitive tissue at the back of the eye. In many cases, this condition has no early warning signs. This is why it's so important for people with diabetes to get a comprehensive dilated vision exam once a year.
The appropriate treatment will vary from person to person, based on the particular type of diabetic retinopathy they have. Unless a person has macular edema, no treatment is required during the first three stages of diabetic retinopathy.
