title: Steady state VER measurement of visual system latency in normal and multiple sclerosis patients.
abstract: VERs were recorded from 30 normal and two multiple sclerosis (MS) subjects using a steady state checkerboard stimulus. The normal subjects produced a mean OU latency of 90.8 msec with a mean absolute interocular latency difference of 3.2 msec. Latencies from the MS patients were up to 13 standard deviations longer than the latencies from the normal subjects.
