A 70-year-old man with a history of hypertension and coronary artery disease suffered an abrupt loss of vision in June 1980. Neuro-ophthalmologic examination in August 1981 revealed 20/20+ acuity in both eyes, but quantitative perimetry disclosed a classic crossed-quadrant homonymous hemianopsia. This is known as the "checkerboard" visual field defect; a right upper quadrantanopsia as well as a left lower quadrantanopsia. A review of the eight previously reported cases is presented. A trial with "checkerboard" Fresnel prisms gave only a slight improvement in ambient field in this patient. The significance of that point is discussed. To our knowledge, this is the first patient with a "checkerboard" occipital lobe infarction pattern documented by computed tomography.
一名患有高血压和冠状动脉疾病的70岁男性在1980年6月突然失明。1981年8月的神经眼科检查显示双眼视力均为20/20+，但定量视野检查发现典型的交叉象限同向性偏盲。这被称为“棋盘格”视野缺损，即右上象限盲和左下象限盲。本文回顾了此前报道的8例病例。该患者试用“棋盘格”菲涅耳棱镜后，周边视野仅略有改善。文中讨论了这一点的意义。据我们所知，这是首例经计算机断层扫描记录有“棋盘格”枕叶梗死模式的患者。
