Abstract

Ocular microtremor (OMT) is a high frequency tremor of the eyes present during fixation and probably related to brainstem activity (Coakley, D. (1983). Minute eye movement and brain stem function. CRC Press, FL.). Published observations on the frequency of OMT have varied widely. Ocular microtremor was recorded in 105 normal healthy subjects using the Piezoelectric strain gauge technique. The dominant frequency content of a signal was determined using the peak counting method. Values recorded ranged from 70 to 103 Hz, the mean frequency being 83.68 Hz (S.D. +/- 5.78 Hz).

摘要

眼球微震颤（OMT）是一种在注视过程中出现的高频眼球震颤，可能与脑干活动有关（科克利，D.（1983年）。微小眼动与脑干功能。CRC出版社，佛罗里达州）。关于OMT频率的已发表观察结果差异很大。使用压电应变仪技术在105名正常健康受试者中记录了眼球微震颤。使用峰值计数法确定信号的主导频率成分。记录的值范围为70至103赫兹，平均频率为83.68赫兹（标准差±5.78赫兹）。
