Physiological nystagmus is a form of involuntary eye movement that is part of the vestibulo-ocular reflex (VOR), characterized by alternating smooth pursuit in one direction and saccadic movement in the other direction. The key signs and symptoms of vestibular neuritis are rotatory vertigo with an acute onset lasting several days, horizontal spontaneous nystagmus (with a rotational component) toward the unaffected ear, a pathologic head-impulse test toward the affected ear, a deviation of the subjective visual vertical toward the affected ear, postural imbalance with falls toward the affected ear, and nausea. indeliberate eye motions comprised of slow drift in one direction, and subsequently, a swift motion in the converse direction, elicited by arousal of the vestibular apparatus while rotating the head. VESTIBULAR NYSTAGMUS: "Vestibular nystagmus is also known as rotational nystagmus." Discussion of vestibular nystagmus.

Seen with peripheral disorders and central disorders, and in two varieties: spontaneous and positional. Horizontal jerk with small amplitude. The movements considered below are the compensatory eye movement (slow component of nystagmus), the vestibulo-ocular reflex (VOR), when the canal in question is stimulated, not the beat or fast component. Horizontal (lateral) canals right and left: VOR response would be to the left and right, respectively. Nystagmus is a back and forth movement of the eyes with the eyes often moving one direction slowly and the other direction more quickly.
