    An arcuate scotoma occurs in the area 10 degrees–20 degrees from fixation. Glaucomatous damage to a nerve fiber bundle containing axons from both the inferonasal and inferotemporal retina resulted in the arcuate defect shown. The scotoma often begins as a single area of relative loss, which then becomes larger, deeper, and multifocal. In its full form an arcuate scotoma arches from the blind spot and ends at the nasal raphe, becoming wider and closer to fixation on the nasal side (Humphrey 24-2 program).
