The study describes neuro-ophthalmologic findings in two patients with brain infarction who developed homonymous hemiachromatopsia with resolution to pure homonymous achromatopsia in an upper quadrant. All other visual parameters were normal; only color perimetry was capable of demonstrating the visual disorder. The results are presented with special emphasis on the macular region. Computed tomography studies and magnetic resonance imaging revealed lesions in the caudal and medial occipitotemporal gyri as well as in adjacent cortical regions. The lesions were secondary to disordered circulation in a proximal occipitotemporal branch of the posterior cerebral artery. The anatomical findings and functional relations of color vision in man are discussed in the light of animal findings.
该研究描述了两名脑梗死患者的神经眼科检查结果，这两名患者均出现了同侧偏侧色盲，随后上象限色盲消退为单纯的同侧偏侧全色盲。所有其他视觉参数均正常；只有颜色视野检查能够显示出视觉障碍。研究结果特别强调了黄斑区。计算机断层扫描和磁共振成像显示，在枕颞叶尾侧和内侧回以及相邻皮质区域存在病变。这些病变继发于大脑后动脉枕颞叶近端分支的血液循环紊乱。结合动物研究结果，讨论了人类色觉的解剖学发现和功能关系。
