Objective:
The objective of this study is to investigate the potential influence of refractive error on Video Head Impulse Test outcomes.
Material And Methods:
Eighty-two patients were included in the study, and all patients underwent video head impulse testing. Patients were divided into four groups according to their refractive error: myopia, myopia-astigmatism, astigmatism, and emmetropia as control.
Results:
Patients with myopia are younger than patients with astigmatism and controls; similarly, patients with myopia-astigmatism are younger than patients with astigmatism. The right and left lateral, anterior, and posterior gain values were statistically significantly lower in the control group compared with myopia and myopia-astigmatism patients (p < 0.05). There was a statistically significant relationship between the right and left lateral, anterior, and posterior gain values and the degree of myopia in the patients (p < 0.05).
Conclusion:
The results of the Video Head Impulse Test gain in myopia patients are higher than that in patients without refractive error. In addition, age may have an effect on gain values. It is important to consider this factor when evaluating the results of the Video Head Impulse Test in patients, and corrections should be made if necessary.
