Patients with established retinopathy should see an ophthalmologist at least once every 6-12 months, as necessary. Three-year retinal screening may be feasible for patients with mild diabetes and no retinopathy. [356]

Early background retinopathy may reverse with improved glycemic control. More advanced retinopathy does not regress with improved glycemia and may worsen, although rarely, with short-term marked improvements in glycemia. Hypertension control is of paramount importance in these latter patients. Results of the randomized, placebo-controlled DIRECT-Protect 2 trial suggested that treatment with the ARB candesartan may improve mild to moderate retinopathy in patients with type 2 diabetes.
