VOR Abnormal, HIT Abnormal

This video is an example of what a patient with bilateral vestibular loss experiences while walking. Without a VOR, there is no mechanism to ensure retinal stability of the world with each head movement, and oscillopsia (illusion of movement of the stationary environment) is the result. Jumpy vision during ambulation or when driving on a bumpy road for example is highly suggestive of bilateral vestibular loss, and head impulse testing and evaluation of the VOR are warranted. Oscillopsia in these patients is not spontaneous (as it would be with nystagmus). To see the eye movements of a patient with abnormal VOR in addition to the oscillopsia, view item: https://collections.lib.utah.edu/details?id=1213435
1, the symptom of oscillopsia with head movements (particularly while walking) is almost universally endorsed by patients with bilateral vestibular loss
