[Drug treatment of diabetic retinopathy]

Medical treatment of diabetic retinopathy remains a problem. So far, no drug has produced definitely positive results. Strict metabolic control still has to be considered the sine qua non of a therapeutic approach to diabetic retinopathy. The extent to which multiple daily injections of insulin (insulin pumps) are capable of inhibiting the development of a retinopathy is still under investigation. Prophylactic measures to prevent further complications where retinopathy already exists should not, however, be neglected.
