What is a VNG procedure?

A videonystagmography (VNG) test uses a special set of goggles with a camera to record your eye movements. It looks for a specific type of eye movement called nystagmus. Your healthcare provider may order this test if you have symptoms of an inner ear disorder.

How do you prepare for Videonystagmography?

Please wash your face thoroughly (mascara, make-up, creams and lotions should NOT be used). Avoid solid foods or milk for 2 to 4 hours before the test. Please do not have any coffee, tea, cola, or caffeine after midnight on the day of the test.

What can be diagnosed with VNG?

A videonystagmography, or VNG, is a test performed to help diagnose balance and motor-related disorders caused by inner ear, visual motor, and sensorimotor integration abnormalities. A pair of goggles are placed over the eyes and infrared cameras record eye movement.

What does a positive VNG mean?

“A person with a concussion, suspected Lyme disease or MS with dizziness or imbalance, may be referred for VNG testing”, she said. “The results can indicate or identify the underlying issue, whether it is due to a central/neurological condition or inner ear disorder.

What is the difference between Videonystagmography and ElectroNystagmoGraphy?

ENG is more affordable than VNG. ENG is used in cases that require measures of eye movements with eyes closed; it is the only method that offers this option. Differences between ENG and VNG include gauging, time and space resolution, and the specificities of the eye movement plane.

What is ElectroNystagmoGraphy and Videonystagmography?

ElectroNystagmoGraphy (ENG) and VideoNystagmoGraphy (VNG) tests are part of a comprehensive evaluation conducted to detect pathologies within the vestibular (balance) system and determine a potential site of lesion: either vestibular end organ or central vestibular system.
