Case 1: Diopsys™ Custom Test OU
The VEPs above were obtained to smaller checks at high contrast (pattern reversal stimulus contains 64 x 64 checks). Under these conditions, the VEP P100 wave was delayed to 160 msec which is nearly a 50 msec difference when compared to the left eye. Such large delays are known to occur because of demyelination, often in Multiple Sclerosis (MS).
