title: Nystagmus episodes related to sea sickness.
abstract: In order to test the possible presence of nystagmus during episodes of sea sickness, we performed electronystagmography (ENG) on nine subjects before and during sailing on a 35-ton vessel in a somewhat heavy sea. In addition, the accelerations of the x, y and z axes of the ship were also monitored and simultaneously recorded. Nystagmus was not detected in pre-sailing recordings, while all of the subjects demonstrated clear positional nystagmus during sailing. The nystagmus was episodic, direction-fixed and its intensity was greater in sea-sick than in non-sick subjects. Our findings suggest that the nystagmus recorded is labyrinthine in origin and stems from temporary peripheral vestibular dysfunction elicited by sea sickness.
