Abstract
It has been proposed that homonymous quadrantanopic visual field loss that respects the horizontal meridian is a pathognomonic sign of extra striate cortical disease. However, two patients with this sign are rep orted-one with a rare striate and the other with an extrastriatal lesi on of the visual cortex. It is therefore hypothesized that a homonymou s quadrantanopia respecting the horizontal meridian may indicate stria te and/or extrastriate cortical disease.
