Abstract

OBJECTIVE: To characterize the response in the video head-impulse test for the assessment of the vestibulo-ocular reflex (VOR) in patients because of vertigo and dizziness.

 

MATERIALS and METHODS: After rightward and leftward head impulses, the following results evaluated were: gain of the reflex and appearance of refixation saccades. A particular type of response (normal gain VOR and refixation saccades) was evaluated in a group of patients.

 

RESULTS: In patients with a unilateral abnormality consisting of normal gain and refixation saccades, there was a close concordance with the diseased side and the side to which head impulses elicited the abnormal result.

 

 

CONCLUSION: In the assessment of patients with dizziness, finding a normal gain VOR with refixation saccades indicates the existence of a peripheral vestibulopathy and localizes to the side of the lesion.
