To study this question DC eye movement recordings of 52 patients with horizontal gaze-evoked nystagmus and/or smooth pursuit deficits were studied in detail. The vestibulo-ocular reflex (VOR) is a reflex acting to stabilize gaze during head movement, with eye movement due to activation of the vestibular system.The reflex acts to stabilize images on the retinas of the eye during head movement, holding gaze is held steadily on a location, by producing eye movements in the direction opposite to head movement. Smooth pursuit gain increased from 0.63 in children aged 5-8 years old to 0.85 in children aged 15-17 years (P = 0.0001). The percentage of gain asymmetry was significantly different in the youngest two groups.
