Training in vHIT
Validation of EyeSeeCam vHIT
Description
Summary of: Mossman, B., Mossman, S., Purdie, G. et al. Age dependent normal horizontal VOR gain of head impulse test as measured with video-oculography. J of Otolaryngol - Head & Neck Surg 44, 29 (2015). https://doi.org/10.1186/s40463-015-0081-7
The aim of this study was to measure the relationship between horizontal VOR gain, velocity and age. The study included 63 participants between the ages of 20 to 80 years old. All hVOR measurements were recorded using the EyeSeeCam™ by Interacoustics. Normative data was collected for each decade of age. The study findings established the mean gain values for both 60ms and 80ms instantaneous gain using the EyeSeeCam™ vHIT system. Whilst the study participants showed a reduction in hVOR gain with age, with lower gains being recorded in older adults. The results of this study allow future comparisons between this normal group and patients with vestibular pathology. The authors conclude that the EyeSeeCam™ vHIT system allowed successful quantitative recordings of eye and head movement during head impulses. This was an advantage over search-coil measurements as it is less invasive, simple to set-up, and readily available for clinicians to utilise.
