pertaining to heat or to calories.
caloric test a test of third, sixth, and eighth cranial nerves. Irrigation of the normal ear with warm water produces caloric nystagmus toward the irrigated side; irrigation with cold water produces similar nystagmus away from that side. Called also oculovestibular test.

Bá·rá·ny ca·lor·ic test(bah'rah-nē),
a test for vestibular function, made by irrigating the external auditory canal with cool and warm water; this thermal stimulation of the vestibular apparatus results in nystagmus and past-pointing; in vestibular disease, the response may be reduced or absent.

caloric testNeurology A test of vestibular function in which the ear canal is irrigated with cold and hot water, which often identifies an impairment or loss of thermally induced nystagmus on the involved side; the use of thermic stimuli to induce endolymphatic flow in the horizontal semicircular canal and horizontal nystagmus by creating a temperature gradient between the 2 sides of the canal

caloric testA test of the balancing mechanisms in the inner ear. Instillation of hot and cold water into the ear causes jerky movement of the eyes (NYSTAGMUS) if the vestibular apparatus is functioning normally. If, however, there is disease of the balancing mechanism (semicircular canals) the nystagmus will be absent or much reduced in extent.
