Diabetic retinopathy is a complication of diabetes, caused by high blood sugar levels damaging the back of the eye (retina). It can cause blindness if left undiagnosed and untreated. However, it usually takes several years for diabetic retinopathy to reach a stage where it could threaten your sight.

Results: Among 449 type II diabetic patients, blindness was seen in 17 (3.79%) (2.02-5.56, 95% Confidence Interval) patients. Among them, 1 (5.88%) had severe non-proliferative diabetic retinopathy, 3 (17.65%) had proliferative diabetic retinopathy and 8 (47.06%) had severe diabetic macular oedema.
Left untreated for a year or longer, macular edema can lead to permanent vision loss.
Typically, diabetic patients will develop diabetic retinopathy after they have had diabetes for between 3-5 years. In the early stages, diabetic retinopathy will not affect the sight, but if it is not treated and progresses, eventually the sight will be affected.
More than 90% of vision loss caused by diabetes can be avoided with early detection and treatment. Intensive management of blood glucose levels can reduce the risk of diabetic retinopathy by 27%.
