Which of the following is not true of caloric test?
Nystagmus can be induced both by cold as well as thermal stimulationCold stimulation causes nystagmus towards opposite side while thermal stimulation causes Nystagmus towards same side. (COWS)In canal paresis either there is a reduced or absent response (causes of U/L canal paresis are-U/L vestibular Schwannoma or vestibular neuritis).B/L absence of caloric nystagmus is seen in case of amminoglycoside ototoxicity or postmeningitis
Induction of nystagmus by thermal stimulation
Normally, cold water induces nystatmus to opposite side and warm water to same side
In canal paresis, the test is inconclusive
None
