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 posterior retina. The extent of capillary nonperfusion was more pronounced in eyes with neovascularization from (in ascending order): the retina, the optic disc, and in the chamber angle.
