Comparison of perfusion parameters (mean (SD)) of patients with insulin dependent diabetes mellitus (IDDM) with different stages of diabetic retinopathy, no (DR-0, n = 22) non-proliferative (DR-1, n = 24), and proliferative (DR-2, n = 18) diabetic retinopathy compared with matched subgroups (MCTL) from a pool of healthy controls (CTL, n = 72)
