This study compared the measurement of VOR in older populations using the 'gold standard' measure of search-coil measurement with the Interacoustics EyeSeeCam™. Six subjects from the older population (age 70 years and older) were recruited. Simultaneous recordings were made using search coils and EyeSeeCam™ during the same manual head impulses. Overt, covert and anti-compensatory eye movements were captured by both methods and demonstrated significant correlation between VOR gain measurements. In this small sample size of older adults vHIT using the EyeSeeCam™ demonstrated significant correlation with the 'gold standard' measurement by search-coil measurement. This study demonstrates the clinical utility EyeSeeCam™ as a portable office based assessment that extends physiologic vestibular testing in the older population.
