Abstract
Pattern-reversal VERs were studied during the visual impairment provoked by exercise in 2 patients with demyelinating optic neuritis. It was found that the transient reduction in visual acuity was correlated to a transient decrease in the amplitude of the major positive component of the VER, whereas no significant changes could be observed in the latency of the response. The normal VER was not influenced by exercise.
摘要
对2例脱髓鞘性视神经炎患者在运动诱发视力障碍期间进行了图形翻转视觉诱发电位（VER）研究。发现视力的短暂下降与VER主要正向成分波幅的短暂降低相关，而在反应潜伏期未观察到显著变化。正常的VER不受运动影响。
