Abstract

A patient lost smooth pursuit gaze to the side opposite a right occipitoparietal hemorrhage. Saccadic gaze was preserved. Pursuit gaze broken by saccades was present toward the side of the lesion. Optokinetic nystagmus (OKN) was defective when a tape was moved toward the patient from the hemianopic fields. Within two weeks, the contralateral pursuit gaze defect had cleared; however, the visual field and OKN defects and the ipsilateral pursuit gaze abnormality persisted.

摘要

一名患者右侧枕顶叶出血对侧的平稳跟踪性眼球注视丧失。扫视性眼球注视保留。向病变侧存在被扫视打断的跟踪性眼球注视。当一条带子从偏盲视野向患者移动时，视动性眼球震颤（OKN）存在缺陷。在两周内，对侧跟踪性眼球注视缺陷已消除；然而，视野和OKN缺陷以及同侧跟踪性眼球注视异常持续存在。
