Abstract
Saccades and vergence were studied in adults with vertigo but without abnormal vestibular function; vertigo was associated with headaches and occurred mostly after prolonged computer work. Horizontal eye movements from both eyes were recorded simultaneously with the IRIS SKALAR device. Several of the specific characteristics of eye movements described previously in controls were not present in vertigo adults: latency of convergence was not longer than that of divergence; components of combined saccade-vergence movements did not have longer latency than pure saccades or vergence; vergence velocity was not accelerated by the saccade during combined movements. Relative to control adults, vertigo subjects showed longer latencies of saccades to distant targets, divergence and convergence (tendency), slower speed for convergence, divergence and vergence components of combined movements. Eye movement abnormalities could be useful for the differential diagnosis of pseudo-vestibular syndrome (without vestibular dysfunction). Oculomotor training is suggested for such subjects with vertigo to improve their abnormal eye movements and reduce symptoms.
