Homonymous Hemianopia, Complete

Homonymous Hemianopia, Complete
Goldmann perimetry demonstrates complete absence of corresponding halves of the visual field---the temporal field in the right eye and the nasal field in the left eye. Each hemifield defect respects the vertical meridian. This is an example of a complete right homonymous hemianopia. The pattern of field loss localizes to the retrochiasmal visual pathways on the left. Note, however, that when homonymous hemianopias are complete, they are relatively non-localizing; the responsible lesion could be at the level of the optic tract, the lateral geniculate nucleus, the optic radiations in the parietal lobe, or the occipital cortex.
