Diabetic retinopathy affects people with diabetes. The leading cause of blindness in American adults, it is caused by changes in the blood vessels of the retina.
This diabetic eye disease weakens the small blood vessels in the retina. Retinal blood vessels can break down, leak, or become blocked - affecting and impairing vision over time. In some people with diabetic retinopathy, damage to the eye can occur when abnormal new blood vessels grow on the surface of the retina.

Hope for the future
Scientists are still working toward a better understanding of diabetic retinopathy, and new treatment options are on the horizon. In the meantime, early detection of retinopathy and close watch by an eye doctor are major goals for the successful treatment of patients with diabetes.
People with diabetes need to know that dangerous changes in the retina often happen before they notice changes in their sight. All people with diabetes should have a professional eye exam at least once a year. The eye doctor can decide if you need more frequent exams. People with diabetes should also get regular medical care to control their diabetes.
