Vestibular Dysfunction

Head tilt is indicative of vestibular disease and is the most consistent sign of a unilateral vestibular deficit. Nystagmus is a term used to denote the involuntary rhythmic oscillation of the eyeballs; the eye movements have a slow phase in one direction and a rapid recovery in the opposite direction, which can be horizontal, rotary, or vertical in character.


Other clinical signs of vestibular dysfunction include ataxia, a wide-based stance, circling, leaning, falling, or rolling toward the side of the head tilt, and positional strabismus, where the eye on the affected side deviates ventrally or ventrolaterally when the head is elevated. Animals with acute vestibular disease can present with anorexia or vomiting associated with the disequilibrium
