The Vestibulo-ocular Reflex and VertigoJames A. Sharpe, Hugh O. Barber This volume reviews clinically relevant studies of the vestibulo-ocular reflex, the otolithic-ocular reflex, and related eye movements and highlights the practical applications of these findings in the management of patients with vertigo (dizziness and/or balance disturbance) and the design of exercise programmes for vestibular rehabillitation. The section on diagnosis and treatment of vertigo addresses conerns such as psychogenic dizziness, imbalance and falls in the aged, and perilymph fistula, and includes descriptions of outpatient and postoperative vestibular rehabilitation programmes and surgical treatment of benign postural vertigo. Nystagmus, a cardinal physical sign of vestibular disorder, is also discussed in detail. Other contributors describe new approaches to testing the vestibulo-ocular reflex and otolithic function. |
