Peak saccade velocity in function HIMP HVOR gain in normal subjects and in patients suffering from different vestibular pathologies and tested at different stages following the lesion. (A) Peak saccade velocity in UVL patients operated for vestibular schwannoma tested at acute stage and normal subjects. Notice that when HIMP gain is low, the peak saccade velocity in acute UVL patients (gray squares) was significantly lower than the ones in normal subjects (black circles). (B) Patients suffering from different vestibular pathologies and areflexic to the caloric test were tested with SHIMPs at chronic stage. Again that the SHIMPs peak saccade velocity vary in function of the HIMP HVOR gain. Gray diamonds: patients with vestibular schwannoma operated after 6 weeks; empty triangle: patients with vestibular schwannoma treated by gamma knife; gray circles: patients suffering from Meniere’s disease and treated by intratympanic gentamycin injection. (C) Peak saccade velocity in BVL Patients and normal subjects. Notice that when HIMP gain is low, the peak saccade velocity in BVL patients (gray triangles) was significantly lower than the ones in normal subjects (black circles).
