Italicized data from the age-matched healthy control subjects. pDVA data in LogMAR units; Time from onset represents number of weeks from condition onset to initiation of vestibular physical therapy; Note that only ipsilesional data was collected on UVH Subject age 58. BVH – bilateral vestibular hypofunction; UVH – unilateral vestibular hypofunction; NL –normal; CS – compensatory saccade; pDVA – passive dynamic visual acuity; Ipsi – ipsilesional head rotation; Contra –contralesional head rotation; L – left, R – right; n/a – not applicable.
