Introduction: The function of the semicircular canal receptors and the pathway of the vestibulo-ocular-reflex (VOR) can be diagnosed with the clinical head impulse test (cHIT). Recently, the video head impulse test (vHIT) has been introduced. Until now there is little clinical experience with the vHIT in patients with vestibular disorders.

Patients and Methods: Using the vHIT, we examined the VOR gain in patients with several vestibular disorders.

Results: Normal hVOR gain and/or the occurence of refixation saccades occur in patients with several vestibular disorders, especially peripheral vestibulopthies.

Conclusions: The vHIT detects abnormal hVOR changes in the combination of gain assessment and refixation saccades. Isolated covert saccades in hVOR changes can only be seen with vHIT.
