Diabetic retinopathy ([ˌrɛtnˈɑpəθi]), also known as diabetic eye disease, is when damage occurs to the retina due to diabetes. It can eventually lead to blindness.[1]

It is an ocular manifestation of diabetes, a systemic disease, which affects up to 80 percent of all patients who have had diabetes for 20 years or more.[2] Despite these intimidating statistics, research indicates that at least 90% of these new cases could be reduced if there were proper and vigilant treatment and monitoring of the eyes.[3] The longer a person has diabetes, the higher his or her chances of developing diabetic retinopathy.[4] Each year in the United States, diabetic retinopathy accounts for 12% of all new cases of blindness. It is also the leading cause of blindness for people aged 20 to 64 years.
