Vertical and horizontal meridian sparing in occipital lobe homonymous hemianopias.

Abstract:

:We report two patients with unique homonymous hemianopias from occipital lobe infarctions. One patient had vertical meridian sparing, and the other displayed horizontal meridian sparing. MRI correlation with the visual field defects confirmed that the vertical hemianopic meridian was represented along the border of the calcarine lips, and the horizontal meridian lies at the base of the calcarine banks deep within the calcarine fissure.
