Diabetic retinopathy is the most common form of diabetic eye disease. Diabetic retinopathy usually only affects people who have had diabetes (diagnosed or undiagnosed) for a significant number of years.
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.
The risk of developing diabetic retinopathy is known to increase with age as well with less well controlled blood sugar and blood pressure level.
