A robust oculocephalic reflex and intact visual acuity with active head movements (dynamic visual acuity) reflect good VOR. Absence of the oculocephalic reflex or a decrease in visual acuity with head movements reflects decreased vestibular function. Nystagmus observed under Frenzel glasses after rapid head shaking reflects asymmetric vestibular input.
