Macular sparing is an indisputable clinical finding in cases of hemianopia. Several explanations have been given, some of which are not mutually exclusive. Eight cases, encountered in a study of more than 100 hemianopias, are presented, in which the sparing has the form of a quadrant, either upper or lower. The explanation in these cases seems to be the double vascular supply to the tip of the occipital pole. It is stressed, however, that macular sparing may have a different explanation in other cases.
黄斑回避是偏盲病例中无可争议的临床发现。对此有多种解释，其中一些并非相互排斥。在一项对100多例偏盲的研究中遇到了8例，其中黄斑回避表现为象限性，即上象限或下象限。这些病例的解释似乎是枕叶极尖端的双重血管供应。然而，需要强调的是，在其他病例中黄斑回避可能有不同的解释。
