Diabetic retinopathy is a complication of diabetes that can cause blurred vision and is a leading cause of blindness. Blood and fluid can leak from small blood vessels that supply the retina. New, abnormal blood vessels may grow and cause problems as well. Controlling blood sugar and blood pressure are important in reducing risk of diabetic retinopathy.
In early stages, there may be little or no symptoms. At more advanced stages, vision may become blurred, distorted, or spots may develop.
A complete eye exam, including dilation, is important to identify and manage diabetic retinopathy. A yearly exam is recommended even in those without symptoms.
