Light-emitting diode (LED), flash (FL) and pattern reversal (PR) stimuli were used to elicit visual evoked potentials (VEPs) in 16 normal subjects (32 eyes) and 39 patients (78 eyes) with signs of visual system abnormality. Latencies and amplitudes (plus standard deviations) of 5 components of each response, correlation coefficients of the normal and abnormal responses and false negatives and positives are presented for the 3 kinds of stimuli. The data show that responses to LED stimuli are very similar to those of FL stimuli and should be useful in the operating room to monitor the visual pathways, if various endogenous factors known to affect late responses can be stabilized.
在16名正常受试者（32只眼）和39名有视觉系统异常体征的患者（78只眼）中，使用发光二极管（LED）、闪光（FL）和图形翻转（PR）刺激来诱发视觉诱发电位（VEP）。给出了三种刺激下每个反应的5个成分的潜伏期和振幅（加上标准差）、正常反应与异常反应的相关系数以及假阴性和假阳性结果。数据表明，对LED刺激的反应与FL刺激的反应非常相似，如果已知影响晚期反应的各种内源性因素能够稳定下来，那么LED刺激在手术室监测视觉通路方面应该是有用的。
