✦ Synopsis

By panretinal fluorescein angiography three patterns (A, B, C) of capillary non peffusion have been identified in 308 eyes with proliferative diabetic retinopathy. Statistical analysis showed their significant association with different retinal complications and clinical parameters. Pattern A (83,7% ; midperipheral location of capillary non perfusion) occurs in type I and II diabetes and is associated with early retinal neovascularization and focal macular edema. Pattern B (8,1%; capillary exclusions disseminated on the whole retina) is typical of young type I diabetics and complicated by early disc new vessels and ischemic maculopathy. Pattern C (8,1%; capillary non perfusion confined to the peripheral retina) is observed in type I diabetic females and associated with multiple retinal new vessels, without maculopathy. This study also demonstrated that eyes with pattern B of retinal ischemia responds less well than others to the laser treatment. Prevalence of different pathogenetic factors could lead to these three distinct types of proliferative diabetic retinopathy.
