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