Visual field changes in branch retinal 'vein' occlusion

The visual field defects in 20 consecutive patients who had branch retinal "vein" occlusions included arcuate nerve fiber bundle scotomas, central scotomas, paracentral scotomas, and segmental peripheral constriction. The role of retinal arteriolar insufficiency in the production of these field defects is discussed. The available evidence suggests that the term "branch retinal vascular occlusion" is a preferable term to describe such clinical findings.
