Training in vHIT
Using vHIT to detect peripheral vestibular disorders (2013)
Description
Summary of: Blödow, A., Pannasch, S., & Walther, L. E. (2013). Detection of isolated covert saccades with the video head impulse test in peripheral vestibular disorders. Auris, nasus, larynx, 40(4), 348–351. https://doi.org/10.1016/j.anl.2012.11.002
This study examined the results of video head impulse testing using the Interacoustics EyeSeeCam™ in 4 groups of peripheral vestibular disorders. The 4 conditions included in the study were 1) vestibular neuritis 2) vestibular schwannoma 3) Meniere's disease 4) bilateral vestibulopathy. The study group include 117 adults (65 females, 52 males). The findings indicated that vHIT was abnormal (reduced gain and refixation saccades) in 79% of cases. The highest abnormality was with VN and bilateral vestibulopathy. The most variability in response was seen in patients with MD and VS. However, no differentiation between acute or chronic vestibulopathy was made in the study population and this may have an effect on the presence of reduced gain and refixation saccades with vHIT. The EyeSeeCam™ vHIT is a reliable method to establish peripheral vestibular changes in hVOR.
