Quizplus · Accepted Answer

Homonymous hemianopia is a visual defect in which half of the visual field is lost in both eyes. It indicates damage to one optic tract, a lateral geniculate body, or area V1 of one occipital lobe. Bitemporal hemianopia is the loss of the outer half of both visual fields and is typically due to damage in the optic chiasm. Color blindness and small scotoma are other types of visual defects that do not specifically indicate damage to these areas.
