Popis:	Introduction: Current clinical practice considers the vestibulo-ocular reflex (VOR) gain as registered by the video head impulse test (vHIT) as the primary measure for semicircular canal function, while the role of the re-fixation saccades (RSs) is still under evaluation. The goal of the study was to appraise the added benefit of RS towards the improvement of vHIT diagnostic accuracy in cases of suspected left horizontal semicircular canal dysfunction. Methods: The vHIT recordings of 40 patients with left-sided horizontal VOR gains Results: Gain values >0.72 were found in all patients with no vestibular disease and in 4 (20%) patients having vestibulopathy. Significantly higher average left-sided RS velocity and frequency were found among the vestibular patients. VOR gain 80% largely improved vHIT diagnostic accuracy. Conclusions: Although VOR gain 80% could improve vHIT diagnostic ability in these patients.
