Paracentral scotoma nerve loss

A paracentral scotoma is an island of relative or absolute vision loss within 10° of fixation. Loss of nerve fibers from the inferior pole, originating from the inferotemporal retina, resulted in the superonasal scotoma shown. Paracentral scotomata may be single, as in this case, or multiple, and they may occur as isolated findings or may be associated with other early defects (Humphrey 24-2 program).
