Videonystagmography

Videonystagmography
Medical diagnostics

Videonystagmography (VNG) is a technology for testing inner ear and central motor functions, a process known as vestibular assessment.[1] It involves the use of infrared goggles to trace eye movements during visual stimulation and positional changes.[2] VNG can determine whether dizziness is caused by inner ear disease, particularly benign paroxysmal positional vertigo (BPPV), as opposed to some other cause such as low blood pressure or anxiety.[3]
