Nystagmographical.examination with a long recorcling portable electronystagmograph was carried out in a patient with vestibular neuronitis. Nystagmus was the direction-fixed nystagmus beating to the healthy side in both the first and follow-up examination during the course of the illness. In the first examination, two days after the onset, nystagmus was recorded frequently. In the follow-up examination, eight days after the onset, nystagmus was recorded only before falling asleep at night and arising early in the morning. The long recording portable electronystagmograph may be useful to monitor the course of vestibular neuronitis.
