Abstract
The effect of artificially varying the pupil size upon the pattern evoked visual response was examined in six healthy subjects and six patients with multiple sclerosis who had abnormal visual evoked responses. Slight depression of amplitude was seen whether the pupil was small or large, but the most obvious effect was a reduction of latency with a large pupil and an increase of latency with a small pupil. It is suggested these phenomena relate to the amount of light entering the eye and not any change of acuity.
摘要
在6名健康受试者和6名视觉诱发电位异常的多发性硬化症患者中，研究了人为改变瞳孔大小对图形诱发视觉反应的影响。无论瞳孔大小，均可见幅度略有降低，但最明显的影响是瞳孔大时潜伏期缩短，瞳孔小时潜伏期延长。提示这些现象与进入眼睛的光量有关，而与视力的任何变化无关。
