electronystagmography

Last reviewed 01/2018

Electronystagmography is a technique which allows the recording of nystagmus on a paper trace. Eye movements are detected by means of electrodes placed at each outer canthus.

Full electronystagmography involves multiple tests including eye movements, caloric testing, head position and eyes open and closed.

Full electronystagmography can answer three questions:

  • whether there is spontaneous nystagmus
  • whether the cause is central or peripheral
  • which side a peripheral lesion is affecting
