What is Diabetic Retinopathy?

Diabetic retinopathy is a diabetes complication caused by damage to the blood vessels of the retina. It can lead to vision loss and blindness if untreated. Key facts: it affects up to 80% of people who have had diabetes for 20 years or more, and early stages often have no symptoms. Advanced stages may require treatments like anti-VEGF injections, laser photocoagulation, or vitrectomy.
