Advanced VNG Test for Vertigo and Balance Evaluation
VNG (Videonystagmography) is a specialized diagnostic test used to evaluate the vestibular system and eye movements in patients experiencing vertigo, dizziness, imbalance, or other balance-related symptoms. It helps assess how the eyes respond to different visual and positional stimuli, providing valuable information about the functioning of the inner-ear balance system.
At Dr. Pareek’s Deafness Clinic and ENT Centre, VNG testing forms part of our comprehensive Balance Services, helping specialists investigate possible vestibular causes of dizziness and develop an appropriate evaluation plan.
When Is a VNG Test Recommended?
Your ENT specialist may recommend VNG testing if you experience:
- Recurrent vertigo or spinning sensations
- Persistent or unexplained dizziness
- Balance difficulties
- Unsteadiness while walking
- Dizziness triggered by head movements
- Nausea associated with vertigo
- Recurrent episodes of imbalance
- Hearing or ear symptoms accompanied by dizziness
- Suspected inner-ear balance disorders
A detailed clinical history and ENT examination are generally performed before deciding whether VNG is appropriate.
How Does VNG Testing Work?
During a Videonystagmography test, specialized video goggles equipped with infrared cameras monitor and record eye movements. These movements provide important information about how the vestibular system and brain coordinate balance.
Depending on the testing protocol, the patient may be asked to:
- Follow specific visual targets.
- Maintain certain head or body positions.
- Move the head in controlled directions.
- Respond to positional changes.
- Undergo specific vestibular stimulation as required.
The recorded eye movements are analyzed to identify patterns that may suggest abnormalities in the balance system.
What Does VNG Evaluate?
VNG can provide information about:
- Eye movement responses
- Vestibular system function
- Positional vertigo patterns
- Possible inner-ear balance abnormalities
- Coordination between the eyes and balance system
- Causes contributing to dizziness and imbalance
The test results are interpreted alongside symptoms, medical history, physical examination, and other investigations.
VNG with Hearing and Balance Assessment
Depending on your symptoms, VNG may be considered alongside other diagnostic tests, including:
- Audiometry
- Tympanometry
- OAE
- BERA
- Clinical vertigo assessment
Combining appropriate tests can provide a more comprehensive understanding of hearing and balance function.
