Failure of suppression of post-caloric nystagmus by fixation. 1982

A Katsarkas, and T H Kirkham

One hundred and seven patients who had failure of fixation suppression (FFS) of their post-caloric nystagmus were studied. Most of them had other ocular motor abnormalities such as defective pursuit, gaze paretic and rebound nystagmus, and saccadic dysmetria. The presence of FFS was unrelated to the type of post-caloric response. The data from this study are compatible with the idea that FFS is a manifestation of a disturbance in the visual-vestibular interaction. While FFS alone is not a useful localizing sign, its presence is patients who are not taking drugs should lead to a search for neurological disease particularly in the posterior fossa.

D001927	Brain Diseases	Pathologic conditions affecting the BRAIN, which is composed of the intracranial components of the CENTRAL NERVOUS SYSTEM. This includes (but is not limited to) the CEREBRAL CORTEX; intracranial white matter; BASAL GANGLIA; THALAMUS; HYPOTHALAMUS; BRAIN STEM; and CEREBELLUM.

D002150	Caloric Tests	Elicitation of a rotatory nystagmus by stimulating the semicircular canals with water or air which is above or below body temperature. In warm caloric stimulation a rotatory nystagmus is developed toward the side of the stimulated ear; in cold, away from the stimulated side. Absence of nystagmus indicates the labyrinth is not functioning.	Barany Test,Barany's Test,Baranys Test,Caloric Test,Test, Barany,Test, Barany's,Test, Caloric,Tests, Caloric
D003388	Cranial Fossa, Posterior	The infratentorial compartment that contains the CEREBELLUM and BRAIN STEM. It is formed by the posterior third of the superior surface of the body of the sphenoid (SPHENOID BONE), by the occipital, the petrous, and mastoid portions of the TEMPORAL BONE, and the posterior inferior angle of the PARIETAL BONE.
