Caloric test with oculogyral illusion as response.
It has been demonstrated that the caloric test can be simplified further by making use of the oculogyral illusion. Since the test is conducted under conditions of optic fixation, this method probably also enhances the sensitivity of the caloric test. The reproducibility of the tests also appears high, at least in respect of measures of "canal paresis". When used in conjunction with other tests for detecting vestibular imbalance, e.g. examination for spontaneous and provocation nystagmus using Frenzel glasses, this OGI caloric test should provide a convenient procedure for the clinical examination of vestibular function.
