Distribution of Capillary Nonperfusion in Early-stage Diabetic Retinopathy

Using composite super-wide fluorescein angiography, 152 eyes with nonproliferative diabetic retinopathy were evaluated for capillary nonperfusion. Four basic types of eyes were distinguished according to the location of capillary nonperfusion: peripheral type 4 eyes, midperipheral type 93 eyes, central type 40 eyes and generalized type 15 eyes. The rate of enlargement of nonperfused area was more rapid in peripheral type, midperipheral type,...
