OBJECTIVE: To aid in defining each phase of Ménière's disease (MD) and underlying vestibular pathophysiology by analyzing the evolving patterns of spontaneous, head-shaking (HSN), and vibration-induced nystagmus (VIN) during and between the attacks of MD.
STUDY DESIGN: Retrospective case series review.
METHODS: We analyzed the patterns of HSN and VIN during 123 attacks from 87 patients who had definite unilateral MD and underwent recording of eye movements both during and between the attacks using video-oculography.
RESULTS: HSN tended to beat toward the lesion side during the irritative phase (80.0%) and toward the healthy side during the paretic phase (82.9%). In contrast, VIN was more commonly induced during the irritative phase (63.7%) and more likely beat toward the healthy side irrespective of the phases evaluated (84.3%). Directional dissociation may occur between HSN and VIN, especially during the irritative phase when HSN mostly beat to the lesion side, but VIN is toward the healthy side.
CONCLUSION: The characteristic patterns of HSN and VIN during each phase of MD would aid in defining the acute phases of MD and understanding the underlying vestibular pathophysiology.
