为了解决多发性硬化症患者视觉诱发电位(VEP)记录和Snellen视力之间的一些报道不一致的问题，我们将这些测试结果与正弦波栅对比敏感度曲线进行了比较。对高空间频率的视觉敏感度降低，而不是低空间频率的疾病，与受影响眼睛的视力下降和小格子VEP减弱有关，而大格子VEP不减弱。当对所有空间频率的视觉敏感度降低时，大格子和小格子VEP均减弱，Snellen敏感度降低。一般来说，对比敏感度曲线的异常预示着VEP波幅的异常，但VEP延迟的预测不太准确。
In an attempt to resolve some of the reported disagreements between visual evoked potential (VEP) recordings and Snellen visual acuity in patients with multiple sclerosis, we compared these test results with sine-wave grating-contrast sensitivity curves. Disease that depressed visual sensitivity for high spatial frequencies, sparing low spatial frequencies, was associated with depressed visual acuity and attenuated small-check VEPs in the affected eye, while large-check VEPs were not attenuated. When visual sensitivity to all spatial frequencies was depressed, both large-check and small-check VEPs were attenuated, and Snellen acuity was reduced. In general, abnormalities in the contrast sensitivity curve predicted abnormalities in VEP amplitude, but VEP delay was less accurately predicted.
