To analyze the frequency in which vibration-induced nystagmus (VIN) with ipsilesional direction appears in subjects with Ménière's disease (MD) or vestibular schwannoma (VS).

Study Design:

Cross-sectional study.


Tertiary referral center.


Fifty-two subjects with MD and 21 subjects with vestibular schwannoma.


Videonystagmographic recordings of VIN at 30, 60, and 100 Hz.

Main Outcome Measures:

Direction and slow phase velocity of VIN at 30, 60, and 100 Hz.


Ipsilesional Nystagmus was observed in 8 of 52 subjects with MD (15.4%) and in 11 of 21 subjects affected of unilateral VS (52.4%). Ipsilesional nystagmus was significantly higher in patients with VS (p = 0.003). The frequency of appearance of ipsilesional nystagmus in the subjects with VS who has not been treated was significantly higher than those who underwent radiosurgery (84.6% vs 0%, p = 0.046).


Ipsilesional vibration-induced Nystagmus can be present in subjects with vestibular deficits caused by MD and VS.
