It has been proposed that homonymous quadrantanopic visual field loss that respects the horizontal meridian is a pathognomonic sign of extrastriate cortical disease. However, two patients with this sign are reported--one with a rare striate and the other with an extrastriatal lesion of the visual cortex. It is therefore hypothesized that a homonymous quadrantanopia respecting the horizontal meridian may indicate striate and/or extrastriate cortical disease.
有人提出，遵循水平子午线的同侧象限盲视野缺损是纹外皮质疾病的特征性体征。然而，本文报告了两名有此体征的患者，其中一名患有罕见的纹状皮质病变，另一名患有视皮质的纹外病变。因此，据推测，遵循水平子午线的同侧象限盲可能提示纹状皮质和/或纹外皮质疾病。
