Diabetes can cause diabetic retinopathy, a sight-threatening complication. Diabetic retinopathy may cause bleeding (hemorrhage), fat leakage (exudates), and swelling in the retina as depicted in the image below. Treatment is usually coordinated with a retina specialist. Depending on how severe the damage in the eye, patients may need laser treatments or injections of powerful medications into the eye to prevent vision loss.
