运动活动影响凝视的方向,眼睑的位置,瞳孔的大小由颅神经III服务,IV,和VI。精神病患者经常遇到异常的动眼活动,并且可以提供很多信息。评估技术包括随意观察和简单的测试,除了专业诊所和研究实验室使用的复杂方法外,不需要任何设备。这篇文章回顾了瞳孔大小,眼外运动,眼球震颤,盖子缩回,盖子滞后,和上眼睑。除了筛查疾病和定位病变,这些测试产生有关个体的高皮质功能的有用信息,锥体外系马达功能,和毒性/药理状态。
Motor activity affecting the direction of gaze, the position of the eyelids, and the size of the pupils are served by cranial nerves III, IV, and VI. Unusual oculomotor activity is often encountered in psychiatric patients and can be quite informative. Evaluation techniques include casual observation and simple tests that require no equipment in addition to the sophisticated methods used in specialty clinics and research labs. This article reviews pupil size, extraocular movements, nystagmus, lid retraction, lid lag, and ptosis. Beyond screening for diseases and localizing lesions, these tests yield useful information about the individual\'s higher cortical function, extrapyramidal motor functioning, and toxic/pharmacologic state.
