Not reported
Date not reportedTo evaluate the effectiveness of both argon laser photocoagulation and aspirin therapy in delaying or preventing progression of early diabetic retinopathy to more severe stages of visual loss and blindness. To help determine the best time to initiate photocoagulation treatment in diabetic retinopathy. To monitor closely the effects of diabetes mellitus and of photocoagulation on visual function. To produce natural history data that can be used to identify risk factors and test etiologic hypotheses in diabetic retinopathy.
