Videonystagmography (VNG) & Electronystagmography (ENG)
Audiologists of the Jefferson Balance and Hearing Center perform a series of noninvasive tests known as videonystagmography and electronystagmography that are designed to document a person's ability to follow visual objects with their eyes and how well the eyes respond to information from the vestibular system.
What Does VNG/ENG Testing Involve?
To measure your visual responses, VNG tests involve the use of video goggles while ENG tests use electrodes. If you are experiencing problems with your balance or you are feeling dizzy, this test will help determine if a vestibular (inner ear) disease is behind the cause of your problem.
Three Parts to VNG/ENG Testing
- Ocular and optokinetic testing: These may indicate a central or neurological problem, or a problem in the pathway connecting the vestibular system to the brain.
- Positional nystagmus: This test is looking at positional changes and their effect on your vestibular system.
- Caloric testing: This test assesses your vestibular system for each ear and reveals whether they are working and responding to stimulation. Testing is conducted with warm and cool water or air.
