Description After assessing static binocular visual acuity, dynamic visual acuity (DVA) is determined by repeating the test during horizontal and vertical head shaking at 2-3 Hz. Dynamic visual acuity is most important to test when bilateral vestibular loss is suspected. A loss of at least 4 lines is typical of bilateral vestibular loss (generally horizontally and vertically), and normal patients without vestibular loss should not lose more than 1 line or so on the acuity chart. Patients with unilateral vestibular loss may loss 2-3 lines on the acuity chart (usually horizontal DVA is more impaired than vertical DVA), and this can vary with the chronicity and degree of vestibular loss.
