caloric reflex test
Barany's test

Any other temperature may cause vertigo, just as used when testing the caloric reflex test.

The simplest one is the caloric reflex test, in which one external auditory meatus is irrigated with warm or cold water or air.

Absent oculovestibular reflexes - no eye movements following the slow injection of at least 50ml of ice-cold water into each ear in turn (the caloric reflex test).

Reflexes include pupillary response (fixed pupils), oculocephalic reflex, corneal reflex, no response to the caloric reflex test and no spontaneous respirations.

A similar test is performed for testing vertigo by using the caloric reflex test, which can be induced by air or water of specific temperatures, typically +/- 7 degrees Celsius from body temperature.

In medicine, the caloric reflex test (sometimes termed 'vestibular caloric stimulation') is a test of the vestibulo-ocular reflex that involves irrigating cold or warm water or air into the external auditory canal.

Another way of testing the VOR response is a caloric reflex test, which is an attempt to induce nystagmus (compensatory eye movement in the absence of head motion) by pouring cold or warm water into the ear.
