Retinal ischemia (capillary nonperfusion) and retinal neovascularization in patients with diabetic retinopathy. 1978

S Merin, and I Ber, and M Ivry

138 diabetic retinopathy patients with good fluorescein angiograms of the macular areas were studied. Areas of capillary nonperfusion (CNP) were surrounded by other capillary abnormalities and were often based on a larger retinal vessel. A satistically highly significant anatomical relationship was found between CNP and neovascularization. In addition, the frequency of neovascularization increased with the increase in size of CNP.
