      Binocular visual evoked responses (VERs) were examined in normal subjects and in patients with prolonged monocular latency.
      Visual evoked responses to binocular stimulation are normally similar to the response to monocular stimulation but are somewhat larger. When conduction from one eye is slowed relative to that from its fellow (as often occurs in demyelinating disease) binocular interaction varies widely. When the interocular difference in latency is substantially elevated the binocular response is often that of the fastest pathway with little or no contribution from the slower pathway. These findings suggest a delayed reciprocal inhibition between the inputs from the two eyes which may suppress late arriving signals.
