Thirty-nine patients with various types of isolated homonymous hemianopias resulting from ischaemic lesions in the posterior parts of the cerebral hemisphere was examined by CAT scanning. Most had localised low density lesions withing the distribution of the posterior cerebral artery. The location of the lesion (deduced from a separate anatomical study of postmortem brain cut in the plane of the CAT scanner) was correlated with visual field defects. Lesions giving rise to quadrantic defects were smaller than those causing total hemianopias; lower quadrantic defects tended to occur in superior cuts and vice versa. Macular sparing was associated with survival of the occipital pole in some instances. Bilateral cases had a higher prevalence of associated defects.
对39例因大脑半球后部缺血性病变导致各种类型孤立性同向偏盲的患者进行了计算机断层扫描（CAT）检查。大多数患者在大脑后动脉分布范围内有局限性低密度病变。病变位置（根据在CAT扫描平面上对死后大脑进行的单独解剖学研究推断）与视野缺损相关。导致象限性缺损的病变比引起完全偏盲的病变小；下象限性缺损往往出现在较高层面的切片中，反之亦然。在某些情况下，黄斑回避与枕极存活有关。双侧病例合并缺陷的发生率更高。
