Nystagmus test

From Biology-Online Dictionary | Biology-Online Dictionary

nystagmus test --> Barany's caloric test

A test for vestibular function, made by irrigating the external auditory meatus with either hot or cold water; this normally causes stimulation of the vestibular apparatus, resulting in nystagmus and past-pointing; in vestibular disease, the response may be reduced or absent.

Synonym: caloric test, nystagmus test.
