A new dynamic visual acuity test to assess peripheral vestibular function.

Objective: To evaluate a novel test for dynamic visual acuity (DVA) that uses an adaptive algorithm for changing the size of Landolt rings presented during active or passive head impulses, and to compare the results with search-coil head impulse testing.

Design: Prospective study in healthy individuals and patients with peripheral vestibular deficits.

Setting: Tertiary academic center.
