Abstract

Two patients with oculomotor palsy caused by midbrain infarction are reported. In the first, pupillary reaction was affected and in the second this reaction was spared. Because the lesions in the anterior part of the tegmentum were in the upper midbrain in the first patient and in the lower midbrain in the second, it is suggested that the pupillary components of the oculomotor nerve are located in the upper midbrain.

摘要

报告了两例由中脑梗死引起动眼神经麻痹的患者。第一例患者瞳孔反应受到影响，第二例患者该反应未受影响。由于第一例患者被盖前部的病变位于中脑上部，第二例患者位于中脑下部，因此提示动眼神经的瞳孔成分位于中脑上部。
