What Is a Videonystagmography (VNG) Test?

A videonystagmography (VNG) test is a specialized diagnostic tool used to assess involuntary eye movements called nystagmus. These eye movements are closely linked to balance and spatial orientation. By measuring how your eyes respond to specific visual stimuli, we can detect issues in your inner ear (vestibular system) and the brain areas that control balance.

Key Purpose: Identifies whether balance problems originate from the inner ear or the central nervous system.
Primary Use: Diagnosing causes of dizziness, vertigo, balance disorders, and related neurological conditions.
Used For: Patients with chronic dizziness, unexplained falls, or suspected vestibular disorders.

According to the NIH, vestibular dysfunction affects an estimated 35% of adults aged 40 years and older in the U.S.

For more in-depth guidance on vestibular disorders and diagnostics, you can also refer to Johns Hopkins Medicine’s vestibular testing guide and our disc injury resource.

How Does the VNG Test Work?

Videonystagmography in Jacksonville, FL works by recording your eye movements using infrared cameras or video goggles while you perform a series of visual tasks and head positions. These responses help identify how effectively your inner ear and brain coordinate to maintain balance.

Key Components of the Test:

Oculomotor Testing: Tracks eye movements as you follow lights or objects on a screen to detect abnormalities.
Positional Testing: Measures nystagmus triggered by specific head positions to identify conditions like BPPV (Benign Paroxysmal Positional Vertigo).
Caloric Testing: Stimulates the inner ear with warm or cold air/water to test the strength of each ear’s balance response.
Gaze Testing: Evaluates your eye movement control while maintaining a fixed gaze or looking in different directions.

Each section helps isolate different parts of your vestibular and neurological systems to provide a clear diagnosis.

How to Prepare for Videonystagmography in Jacksonville, FL

Preparing properly for your VNG test ensures more accurate results:

Avoid caffeine, alcohol, or sedatives 24 hours before the test.
Do not wear makeup, especially around the eyes.
Bring a list of current medications for review.
Wear comfortable clothing for easy head movement.

What Do the Results Mean?

Once completed, your VNG results are analyzed by our chiropractic neurologist and team to determine the cause of your symptoms. Here’s how they may be interpreted:

Normal VNG: Likely indicates your balance issues are not caused by your inner ear.
Abnormal VNG: Could indicate vestibular dysfunction, central nervous system pathology, or BPPV.
Localized Findings: Help pinpoint the specific area (left vs. right ear, central vs. peripheral cause).

At East Coast Injury Clinic, we take the time to explain your results in plain language and outline the next steps for recovery. Learn how our chiropractic adjustments and eye tracking therapy complement your care.

Heather and Ariyana are always welcoming! The staff is unbelievable sweet and thoughtful. Very considerate of everyone and their time. Never ever feels like a gimmick. I truly wish this company could be my family doctor as well! Nothing like healing in the right place, the right time with the right people.

The sessions are excellent, with a highly skilled and friendly staff. The physical exercise staff, massage, and chiropractic sessions are all great. When I first arrived, I had limited mobility, but thanks to their effective treatments, I already feel a significant improvement in my healing process. I am extremely grateful to each and every one of you.

This place is amazing! The staff is super friendly. The physical therapists are kind and understanding and helped me heal. The doctors listened to all my concerns! I would highly recommend to anyone who wants to feel better! Bianca is hands down the BEST manual therapist and Bradley was often my PT and is very knowledgeable.

I feel like my treatment is in great hands. The organizational culture in this office is superb. Everyone is always happy and get along with each other. Most importantly, they show sincere appreciation and care for every single patient. The office manager is the BEST as well.

Absolutely love love love this place. I’ve done treatment here twice now after two car accidents within a year. Dr.V and her team are so sweet, super caring and will absolutely help you with whatever. Bianca is the most sweetest person I’ve ever met in my life, I enjoy all the conversations I get to have with her doing our Manual sessions.

I cannot express how helpful this amazing business is! Tried out their Shockwave therapy and I will forever sing its praises. It was immediate relief! The staff is so very kind and knowledgeable the second you walk in the door! Ms Connie was the best person with such a gentle touch for the Shockwave. She explains as she goes and continues to ask if it is feeling okay. Cannot recommend enough! Reach out to them, you will not regret it! ~ Linda G.
