Definition: Diabetic retinopathy is a complication of both Type 1 and Type 2 diabetes. When blood glucose levels remain too high for a long period of time, changes can occur in the tiny blood vessels that supply the retina of the eye. A person may notice strange blotches, blurriness, or dark spots in their vision. If this happens, a visit to an eye doctor or specialist is extremely important. If retinopathy is not treated it can lead to blindness.
