WebbPURPOSE To investigate the correlation between directional asymmetry in ocular responses to monocularly viewed optokinetic stimuli (monocular optokinetic nystagmus, MOKN) and sensory fusion in infants and toddlers with early-onset esotropia. METHODS Subjects were 14 infants and toddlers with early-onset esotropia (7-26 months old; … WebbTip: horizontal-rotary nystagmus with a fast phase that does not change directions in extremes of gaze (“non direction-changing”) and whose amplitude increases with gaze … signs of rack and pinion going bad

The direction of the nystagmus, by convention, is named for the fast phase, so the spontaneous nystagmus … WebbNystagmus is divided into a fast phase and a slow phase. The slow phase drives the nystagmus, it is the manifestation of the slow drift toward the affected ear caused by the lesion. For example, a lesion in the left vestibular system will cause a slow drifting of the eyes toward the left. WebbPendular Nystagmus: a type of nystagmus resulting in oscillation of equal amplitude with no fast or slow phases. The eye moves in a sinusoidal trajectory that is similar to that of a pendulum. The pendular movements of the eyes may be in any direction including vertical, horizontal, torsional, or a combination thereof. signs of rabies in humans after bite
