Video head impulse test (vHIT) was found to be more sensitive than the clinical head impulse test (cHIT) in identifying symptoms of disorders impacting vestibulo-ocular reflexes, particularly isolated covert saccades. Vestibular disorders identified by vHIT include unilateral vestibular neuritis and unilateral or bilateral gentamicin vestibulopathy. vHIT was found to be a complimentary test with caloric test for identifying Meneire's disease and vestibular schwannoma. Because no nausea or vomiting is associated with vHIT, this test was found to be well tolerated by patients.
