[End position nystagmus caused by prolonged lateral gaze (author's transl)]

Electronystagmograms were recorded from six normal subjects who had to maintain an extreme sideward gaze either in the dark or using a fixation target. End position nystagmus occured in three subjects immediately, in two subjects with a latency of several seconds, and in one subject with a latency of 90 seconds. The nystagmus was typically dissociated and was similar whether the subject viewed a fixation point or was recorded from in darkness.
