Abstract:
Objective:Dynamic visual acuity (DVA) is defined as the visual acuity when there are relative movements between subjects and visual targets. The purpose of this study was to discuss the correlation between bedside DVA test and other examinations of vestibular function, and to assess the value of DVA test for clinical diagnosis.
Methods:Retrospective analysis of 323 cases with peripheral vestibular disorder, and analyzing the correlation between bedside DVA results and caloric test were performed.
Results:Out of these 323 cases, 113 cases showed positive results of DVA.Among these 113 cases with positive DVA test, 109 cases were bilateral or unilateral vestibular function loss according to the results of caloric test or VEMP. The disease with the highest positive rate of DVA was bilateral vestibulopathy(BVP), followed by vestibular neuritis (VN) and profound sudden sensorineural hearing loss (pSSNHL).
Conclusions:Bedside DVA is effective to determine the cases with BVP and severe unilateral vestibular function loss.
