Title: Effects of Candesartan Cilexetil (Candesartan) on Diabetic Retinopathy in Type 1 Diabetic Patients Without Retinopathy.
Brief Summary: The primary objective is to determine whether candesartan, compared to placebo reduces the incidence of diabetic retinopathy in normotensive, normoalbuminuric type 1 diabetic patients without retinopathy.

The secondary objective is to determine whether candesartan, compared to placebo, beneficially influences the rate of change in urinary albumin excretion rate (UAER).

This study is part of the DIRECT Programme also including secondary prevention studies of diabetic retinopathy in both type 1 and type 2 diabetes. The primary objective for all three pooled studies is to determine whether candesartan, compared to placebo, reduces the incidence of microalbuminuria in type 1 and type 2 diabetic patients.

* History of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or that might affect interpretation of the results of the study or render the subject at high risk from treatment complications.
