We evaluated the macular lesions in 141 eyes, 74 cases, of diabetic retinopathy. The diabetic retinopathy was simple in 40 eyes, preproliferative in 61 and proliferative in 40. We used fluorescein angiography in the evaluation.

Perifoveal capillary occlusion was significantly associated with increased extravasation of dye in the macula and with impairment of visual acuity. In 3 out of 5 eyes with extensive perifoveal capillarynonperfusion, neovascularization developed from perifoveal retinal vessels. There were 16 eyes show-ing granular background hyperfluorescence sugges-tive of retinal pigment epithelial atrophy. The presence of macular edema was generally associat-ed with poor visual acuity. The retinal pigment atrophy progressed to pattern dystrophy in some eyes.
