Distribution of retinal fluorescein angiographic capillary nonperfusion in proliferative and preproliferative diabetic retinopathy / 眼科

ABSTRACT

Examination of composite retinal fluorescein angiograms of 381 eyes (227 cases) with proliferative and preproliferative diabetic retinopathy revealed that4 basic patterns of capillary nonperfusion were reeognizable, i. e., (1) the peripheral type, 20 eyes (5.3%), (2) the mid-peripheral type, 974 eyes (71.9%), (3) the. posterior central type, 39 eyes (10.2%), and (4)the generalized type, 48 eyes (12.6%). The progressive tendency and prognosis of each type were discussed.
