Transient visually evoked potentials (VEPs) to sinusoidal gratings over a range of spatial frequencies have been recorded in cases of optic neuritis. The use of the response to pattern onset in addition to the response to pattern reversal extended the range to higher spatial frequencies by up to two octaves. There was an increase in VEP delay and a greater degree of discrimination from a control group at higher spatial frequencies. This finding is discussed in the light of previous reports of luminance and checkerboard VEPs in demyelinating optic nerve disease. An attempt is made to relate amplitude changes in various VEP components to contrast sensitivity measurements in this group of patients.
在视神经炎病例中，已记录了在一系列空间频率下对正弦光栅的瞬态视觉诱发电位（VEP）。除了对图形反转的反应外，使用对图形起始的反应将范围扩展到更高的空间频率，最高可达两个八度。在更高的空间频率下，VEP延迟增加，与对照组的差异更大。根据先前关于脱髓鞘性视神经疾病中亮度和棋盘格VEP的报告对这一发现进行了讨论。试图将该组患者各种VEP成分的幅度变化与对比敏感度测量相关联。
