"videonystagmography" 的定义和意义

What is "videonystagmography"?

Videonystagmography (VNG) is a diagnostic test used to evaluate how well the inner ear and brain are working together to control eye movements and balance. During the test, a small camera or video goggles are worn by the patient to record eye movements in response to various triggers, such as changes in head position, temperature, or visual patterns. VNG helps diagnose conditions that affect balance and dizziness, such as vestibular disorders, Meniere’s disease, or vertigo, by analyzing how the eyes move and respond to these triggers.
