Diabetic Retinopathy : Causes, Symptoms & Treatment

It is an eye disease that is caused by diabetes. Diabetic Retinopathy is caused when high blood sugar levels cause damage to the blood vessels in the retina. These blood vessels can close, stopping blood from passing through or can swell and leak. The retina is a light-sensitive membrane covering the back of the eye that sends signals to the brain via the optic nerve. Diabetic Retinopathy can develop in patients who have either type 1 or type 2 diabetes.

There are three different types of Diabetic Retinopathy

Background retinopathy

Diabetic maculopathy

Proliferative retinopathy
