Central visual field in patients with retinal branch vein occlusion

We studied the central visual fields in 11 eyes with retinal branch vein occlusion that presented extensive areas of capillary nonperfusion by fluorescein angiography. Relative scotomata corresponding to the areas of capillary nonperfusion were seen in seven eyes where the venous occlusion was of recent onset (average, 11 months). In the remaining four eyes with long-standing venous occlusion (average, 24 months), capillary occlusion was associated with absolute scotomata.
