Diabetic retinopathy and its relation to type of diabetes: review of a retinal clinic population.

A detailed survey was performed of 100 consecutive diabetic patients with severe retinopathy referred to a retinal clinic. They were classified as having either type 1 (insulin-dependent) or type 2 (noninsulin-dependent) diabetes. There were significant associations between an initial diagnosis of maculopathy. There was a significant association between male sex and proliferative retinopathy. Referral patterns to this clinic and the medical supervision of the patients are discussed.
