Purpose
To compare the results of video head impulse test (vHIT) and caloric testing (CT) in patients with vestibular migraine (VM) and Ménière’s disease (MD) and to investigate the relationship between these two tests.
Methods
Patients with definite unilateral MD and VM were included in the study. All patients underwent both vHIT and CT. The vestibulo-ocular reflex (VOR) gains of lateral semicircular canals and saccadic waves in vHIT and the canal paresis factor for the CT were examined.
Results
CT was found abnormal in 39 (66.1%) patients with MD and in 17 (34%) patients with VM, while abnormal gain of the lateral canal was obtained in 23 MD (39%) patients and 9 (18%) VM patients. In all, 11.9% of patients with an abnormal vHIT had a normal CT, whereas 33.9% of those with an abnormal CT had a normal vHIT.
Conclusion
Loss of VOR detected by caloric testing is more common and severe in MD than VM. Although vHIT is useful and can give complementary information, vestibular testing with the caloric test still seems more sensitive for detecting hVOR pathology.
