Diabetic retinopathy is a major cause of sight loss in people with diabetes, with a high risk of macular oedema, vitreous haemorrhage or other complications. Panretinal photocoagulation is the primary treatment for proliferative retinopathy. Anti-vascular endothelial growth factor drugs are used to treat various eye conditions and may be beneficial for people with proliferative or non-proliferative retinopathy.
