Vestibular Testing Diagnostic
Typical Use
Record eye movements to evaluate vestibular function and nystagmus.
Description
A system combining infrared video goggles and computerized analysis to record and quantify spontaneous, gaze evoked, and positional nystagmus as well as responses to caloric stimulation, aiding diagnosis of peripheral versus central vestibular disorders and guiding vestibular rehabilitation. VNG testing requires patient cooperation, controlled stimuli, and interpretation by clinicians experienced in vestibular physiology; results inform treatment plans for vertigo, balance disorders, and vestibular neuritis. Integration with vestibular evoked myogenic potentials and imaging enhances diagnostic precision in complex cases.
