Abstract

Two patients developed unilateral occipitotemporal infarcts that produced inferior quadrantic achromatopsia and an accompanying superior quadrantanopia. Magnetic resonance imaging and single-photon emission computed tomographic studies of both patients supported the current view that color vision is encoded in the lingual and fusiform gyri. Although the quadrantic defect in color processing was profound, neither patient was aware of it. Simple bedside testing of patients with superior quadrantanopia may disclose an unrecognized quadrantic achromatopsia.

摘要

两名患者出现单侧枕颞叶梗死，导致下象限性色盲及伴随的上象限盲。对这两名患者进行的磁共振成像和单光子发射计算机断层扫描研究支持了目前关于颜色视觉在舌回和梭状回中编码的观点。尽管颜色处理方面的象限性缺陷很严重，但两名患者均未意识到这一点。对上象限盲患者进行简单的床边测试可能会发现未被识别的象限性色盲。
