Diabetic retinopathy is the most common diabetic eye disease and may lead to blindness if untreated. It is caused by changes in the blood vessels of the retina. All people with diabetes, both type 1 and type 2, are at risk of developing diabetic retinopathy. Therefore, everyone with diabetes should get a comprehensive dilated eye exam at least once a year. Diagnosis of Diabetic Macular Edema may require testing with Ocular Coherence Tomography (OCT).

Screening, monitoring and treating diabetic retinopathy with retinal laser and / or intravitreal injection of anti-VEGF drugs are readily accessible.
