Figure 3: Ocular vestibular evoked myogenic potential waveforms in a Meniere's patient stage IV with affected left ear. The upper and lower waveforms are responses to 500 and 1000 Hz stimuli, respectively. The right ear shows normal frequency tuning with the 500 Hz responses being slightly enhanced (a). The left ear shows altered frequency tuning with the 1000 Hz responses being greater in amplitude compared with the 500 Hz waveforms (b)
