Dynamic Visual Acuity and Gaze Stabilization in a Clinically Normal Population of Military-Trained Aviators
Abstract
The dynamic visual acuity (DVA) test and gaze stabilization test (GST) are functional assessments of the vestibuloocular reflex. Both the DVA test and GST have shown great sensitivity/specificity in the identification of unilateral and bilateral peripheral vestibular deficits. The DVA test is recommended for inclusion in fitness-for-duty evaluations for military occupations, like that of aviators. The goal of the current study was establish a reference dataset for clinically normal military aviators on both the DVA test and GST. Forty-four military trained aviators completed the informed consent process and participated in this study. The data from 40 participants were analyzed. Results of this study suggest that military aviators are high-performers when compared to the publically available results from populations of clinically normal adults. The results from this study may provide the practicing clinician a comparative normal cohort when analyzing and interpreting the VOR function in military aviators.
