Diabetic retinopathy is a disease of the retina, the thin tissue that lines the back of the eye. The condition is a complication of diabetes. It is related to long-term high blood sugar levels. Over time, this leads to changes in blood vessels that interfere with oxygen delivery to the cells in the retina.
