CALORIC STIMULATION TEST
- Caloric stimulation test is done to detect disorder of the inner ear like meniere's disease. Alternating warm and cold water will be used.
- Instillation of warm water produces horizontal nystagmus toward the irrigated ear if the 8th cranial nerve is normal.
- Instillation of cold water will produce horizontal nystagmus away from the side of the irrigated ear if the brainstem is intact
- Severe nystagmus indicates normal inner ear
- Moderate nystagmus indicates Meniere's disease
- No nystagmus indicates acoustic neuroma
