PURPOSE
To evaluate the latency of visual evoked potentials (VEPs) in healthy women during and after menstruation.
METHODS
Pattern and flash VEPs were performed in 15 healthy women aged 18 to 25 years on the maximum bleeding day (luteal phase) and 7 days after the menstrual cycle (follicular phase).
RESULTS
Mean latency was 119.6 msec on the maximum bleeding day and 100.8 msec one week after menstruation on pattern VEP (P < 0.001). Corresponding values for flash VEP were 124.5 msec and 112.7 msec, respectively (P < 0.001).
CONCLUSION
Prolonged VEP latency on the maximum bleeding day indicates that high progesterone levels may have an inhibitory effect on optic nerve conduction velocity.
目的
评估健康女性在月经期间及月经后视觉诱发电位（VEP）的潜伏期。
方法
对15名年龄在18至25岁的健康女性，在月经出血量最多的那天（黄体期）和月经周期结束后7天（卵泡期）进行图形和闪光视觉诱发电位检测。
结果
图形视觉诱发电位在月经出血量最多那天的平均潜伏期为119.6毫秒，月经结束一周后为100.8毫秒（P < 0.001）。闪光视觉诱发电位的相应值分别为124.5毫秒和112.7毫秒（P < 0.001）。
结论
月经出血量最多那天视觉诱发电位潜伏期延长表明，高孕酮水平可能对视神经传导速度有抑制作用。
