Midperipheral Fundus Involvement in Diabetic Retinopathy

We evaluated the topologic distribution of vaso-occlusive and vasoformative lesions in 119 eyes with diabetic retinopathy using our newly developed super-wide (130 degrees) fluorescein angiographic montage technique. A numeric coding system was applied to assess the vaso-occlusive lesions by dividing each fundus maximally into 418 blocks. We demonstrated that the midperipheral retina was far more prone to undergo capillary nonperfusion than the...
