What is Videonystagmography (VNG) Testing?

VNG testing determines if a vestibular (inner ear) disease is the source of your dizziness or balance problems. This series of tests evaluates your ability to follow objects with your eyes and measures how well the eyes respond to information from the vestibular (inner ear) system.

What do your eyes have to do with your ears?

Neural pathways connect the inner ear balance mechanism to eye muscles. A disorder of the balance mechanism can result in quick eye movements that can only be detected with advanced optics.

An older test, called electronystagmography (ENG), used electrodes to measure the muscle activity around the eye. VNG testing, which uses a special infrared camera to measure eye movements, is much more comfortable for patients and yields more accurate results. VNG is also the only test that can distinguish between unilateral (one ear) and bilateral (two ear) vestibular loss, so it’s easy to understand why audiologists have adopted it as the new best-practice technique for evaluating inner ear functions.

VNG testing also addresses ear functionality to determine if a vestibular deficit might be causing your balance or dizziness problems.

What to Expect During VNG Testing

You’ll wear goggles fitted with an infrared camera that will record your eye movements as you look back and forth between designated points, track moving lights, and move your head and body into different positions.

Although you might feel minor discomfort from wearing the goggles, VNG testing is painless and non-invasive. Appointments last about 1 ½ hours, and all insurances cover the testing.

Steps of VNG Testing

The 4 main parts of VNG testing include:

  1. Ocular Mobility: Here, you’ll use your eyes to follow objects that jump from place to place, stand still and move smoothly. As you follow these visual targets, our team will look for inaccuracies or slowness that could indicate a neurological or central nervous condition, or trouble with the pathway between the brain to the vestibular system.
  2. Optokinetic Nystagmus: Your team will ask you to view a large, moving image to see if your eyes properly track such movements. Like the ocular mobility segment, we’ll be examining your ability to follow visual targets.
  3. Positional Nystagmus: Our technician will place your body and head into different positions to ensure that there aren’t inappropriate rapid eye movements as you move. This test examines your inner ear system and the endolymph fluid in your semi-circular ear canals. We’re verifying that otoconia, or small calcium carbonate particles, aren’t disturbing the natural flow of fluid.
  4. Caloric Testing: One at a time, our team will simulate your inner ears with warm, followed by cool, air. We’ll monitor your eye movements to ensure that both of your ears sense and respond to stimulation. This is the portion of the test that can distinguish between unilateral and bilateral vestibular loss.

Based on your VNG test results, your audiologist may recommend hearing aids or other medical treatments to correct your dizziness or balance disorder. Schedule your VNG testing with Hearing Associates by calling 888.760.2032.

An Audiologist is a licensed health care professional who diagnoses hearing loss, balance problems and vestibular system conditions of the ear. They are trained to diagnose, prevent and manage these conditions. After a review of your health history and a hearing evaluation, an audiologist will determine if your condition might be medically treatable. If your condition is not medically treatable, they will make recommendations for treatment which might include the use of hearing aids, listening devices, balance therapy and aural rehabilitation.

What Education is Required to Become an Audiologist?

Audiologists need to have either a masters or doctoral degree in audiology from an accredited university. They are regulated by state licensure or registration in all 50 states and the District of Columbia. The profession’s requirements are transitioning into requiring a doctorate as the initial degree to practice audiology.
Minimum requirements for the degree include:

  •  A minimum of 75 semester hours of post-baccalaureate study
  • Meeting prescribed competencies
  • Passing a national exam given by Praxis Series of the Educational Testing Service
  • Teaching programs that are equivalent to a minimum of 12 months of full-time, supervised experience.

Audiologists will also earn a certificate from the American Speech-Language-Hearing Association or through the American Board of Audiology (ABA). To remain licensed, most states have continuing education and renewal requirements that must be met.

Where do Audiologists Work?

Audiologists will work in a variety of settings:

  • Hospitals and medical centers
  • Schools and universities
  • Clinics and rehabilitation facilities
  • Cochlear implant centers and speech and hearing centers
  • Private audiology practices, otolaryngology (ENT physician) and hearing aid dispensing offices
  • Hearing aid manufacturing facilities

What is a Typical Day for an Audiologist?

In a 40-50 hour work week, Audiologists are involved in the testing, diagnosis and management of hearing loss in patients of all ages. An audiologist can refer their patients to physicians when the history and results of their audiometric evaluation show the possibility of a serious condition. They also dispense hearing aids and listening devices, counsel families through any new diagnosis of hearing loss, and help educate about managing of the patient’s condition. Audiologists help minimize the negative effect of these disorders for their patients, leading to improved outcomes.
