Diagnostic value of refixation saccades in the Video Head Impulse Test (vHIT) in unilateral definite Meniere's disease.

We currently interpret the video Head Impulse Test (vHIT) results mainly based on the gain value. The purpose of this study is to evaluate vHIT results for both gain and re-fixation saccades on unilateral definite Meniere's disease (MD) subjects in comparison with normal healthy subjects. Forty unilateral definite MD subjects and age-matched healthy subjects were recruited.
