videonystagmography, also called a VNG test, records eye movements during a vertigo or balance assessment. Because the inner ear and eye movements are linked, this test can give useful clues when dizziness, spinning, imbalance or unclear vertigo keeps coming back.

In simple words, VNG does not replace the doctor's examination. It helps connect your symptom story with eye-movement patterns, positional testing, hearing symptoms and the next useful treatment or rehabilitation plan.

First, choose the right path

Book a clinic review when dizziness is recurrent, confusing, mixed with imbalance, or not improving after initial treatment. Go to emergency care first for new weakness, facial droop, slurred speech, double vision, severe new headache, fainting, chest pain, sudden hearing loss, repeated vomiting, a serious fall, or inability to walk safely.

What videonystagmography means

Videonystagmography uses goggles or cameras to record eye movements. The test looks for patterns of nystagmus, which means involuntary eye movement. These patterns can support a diagnosis when the symptoms may be coming from BPPV, vestibular weakness, vestibular migraine, Meniere's disease, medicine effects, anxiety-related dizziness or a central neurological cause.

Patients do not need to memorize the anatomy. The useful question is: does the test result fit the timing, trigger and body clues you are feeling?

When a VNG test for vertigo is useful

A VNG test for vertigo is most useful when the diagnosis is not clear from history and examination alone, when attacks are recurrent, when imbalance persists after an acute episode, or when treatment has not matched the symptom pattern. It may also help before planning vestibular rehabilitation therapy.

If the dizziness is clearly positional, the doctor may first perform positional testing and compare the result with the BPPV treatment pathway. If symptoms include hearing change, tinnitus or ear fullness, hearing tests may be needed with the balance test.

What happens during videonystagmography

The test may include watching moving targets, checking eye movements in different head or body positions, and in some protocols, warm or cool air or water stimulation in the ear. The exact test set depends on the clinic and the patient's safety profile.

Tell the doctor about neck stiffness, recent ear surgery, severe anxiety, heart symptoms, pregnancy, current medicines, migraine history and whether loud sounds trigger dizziness. These details can change which parts of vestibular testing are appropriate.

Some patients feel short dizziness or nausea during parts of the test because the aim is to safely reproduce useful eye-movement clues. This does not mean the test is dangerous by itself, but it should be planned carefully if the patient is frail, has severe vomiting, cannot sit safely, or has symptoms that sound more like fainting than spinning vertigo.

How I use the VNG result in clinic

I use VNG as one part of the decision, not as a standalone label. A report should be read with the patient's timeline, eye examination, ear symptoms, walking confidence, fall risk, migraine features, blood pressure history and previous reports.

This reduces two common mistakes: calling every dizzy spell BPPV, or using tablets repeatedly without checking the actual balance pathway. The best result is a clearer next step – repositioning maneuver, vestibular rehab, hearing review, migraine care, medical review, or urgent referral when red flags are present.

A helpful report should answer a practical question: does the pattern support an inner-ear balance weakness, positional vertigo, a mixed vestibular picture, or a need to look outside the ear? If the report and symptoms do not match, the answer is not to ignore the patient. The answer is to review the history, medicines, blood pressure, migraine pattern, hearing symptoms and neurological signs again.

What to bring for the appointment

Bring old audiometry reports, VNG or ENG reports, MRI or CT reports, medicine list, videos of visible eye movements if available, and a short note of when the dizziness starts, how long it lasts, and what triggers it. Mention whether you feel spinning, floating, fainting, imbalance, ear pressure, tinnitus, hearing change, headache, neck pain or fear of falling. These patient words help the test result make sense.
