Abstract

A 52-year-old steelworker displayed a consistent defect in leftward voluntary gaze across the midline. Both fast (saccadic) and slow (pursuit) eye movements were affected. Neuro-ophthalmologic evaluation revealed no additional neurologic or ophthalmologic deficit. Pupilary miosis occurred during leftward gaze attempt, indicating that the gaze palsy was due to spasm of the near reflex. Special maneuvers during clinical eye movement testing disclosed full ability to make normal horizontal fast and slow eye movements despite the apparent defect in "voluntary" leftward gaze.

摘要

一名52岁的钢铁工人在向左越过中线的随意注视中表现出持续的缺陷。快速（扫视）和慢速（跟踪）眼球运动均受到影响。神经眼科评估未发现其他神经或眼科缺陷。在试图向左注视时出现瞳孔缩小，表明注视麻痹是由于近反射痉挛所致。临床眼球运动测试中的特殊操作显示，尽管“随意”向左注视存在明显缺陷，但仍完全有能力进行正常的水平快速和慢速眼球运动。
