Find the real cause of your vertigo & dizziness
Get a complete VNG test in Patna at Mom’s Care, Rajendra Nagar. Our infrared-goggle assessment helps identify inner-ear weakness, BPPV and abnormal balance responses so your treatment can be based on objective findings.
What is a VNG test?
Videonystagmography is a computerised, non-invasive test that evaluates the relationship between your eyes, brain and inner-ear balance system.
The inner ear and eyes are connected through the vestibulo-ocular reflex. When one side of the balance system becomes weak or sends incorrect signals, the eyes may make small rhythmic movements called nystagmus.
Infrared VNG goggles record these movements during visual, positional and vestibular tasks. The findings help determine whether dizziness is more consistent with an inner-ear disorder or a pattern requiring further medical or neurological evaluation.
VNG does not treat vertigo by itself. It gives your clinician objective information so repositioning, rehabilitation or medical referral can be selected more accurately.
Common causes of vertigo and imbalance
“Dizziness” can describe several sensations. A structured vestibular assessment helps convert these symptoms into measurable findings.
BPPV or loose inner-ear crystals
Positional and Dix-Hallpike recordings can identify the direction, latency and duration of nystagmus and help determine the affected ear and canal.
Vestibular neuritis and labyrinthitis
Caloric testing compares responses from both ears and may quantify one-sided vestibular weakness after inflammation or infection.
Inner-ear fluid imbalance
Episodic vertigo, tinnitus, ear pressure and fluctuating hearing require correlation with audiometry and ENT evaluation.
Vestibular migraine
A near-normal peripheral VNG result may redirect evaluation toward migraine-related or visually triggered dizziness.
Bilateral vestibular loss
Reduced responses on both sides may explain poor balance in darkness, frequent falls or bouncing vision while walking.
Central vestibular warning patterns
Abnormal saccades, pursuit, gaze stability or fixation suppression may indicate that medical or neurological evaluation is appropriate. VNG is a screening tool and does not replace neurological examination.
Cervical dizziness
Testing helps assess whether a vestibular deficit is present alongside neck stiffness, injury or postural problems.
Tinnitus and dizziness
VNG with hearing tests provides a broader view when tinnitus, hearing changes and dizziness occur together.
Falls and age-related imbalance
Findings can support personalised balance retraining, mobility planning and fall-prevention strategies.
Seek emergency medical care for sudden vertigo with slurred speech, facial or limb weakness, double vision, fainting, severe headache, chest pain or sudden hearing loss.
Four important parts of a complete VNG test
Each stage examines a different part of the eye and balance pathways. Together, they create a more useful clinical picture.
Oculomotor tests
Gaze, saccade, smooth-pursuit and optokinetic tasks assess how accurately the eyes follow stationary and moving targets.
Spontaneous nystagmus
Eye movements are recorded while the head remains still, with and without visual fixation.
Positional testing
Dix-Hallpike and other positions assess whether movement triggers canal-specific BPPV nystagmus.
Caloric assessment
Warm and cool stimulation evaluates each ear separately and may identify unilateral or bilateral weakness.
What happens during a VNG appointment?
Your appointment follows one connected clinical journey—from history and examination to report interpretation and treatment planning.
Your vertigo history is mapped
The clinician records the type, duration and triggers of dizziness, medicines, hearing symptoms, migraine history and previous injuries.
Ear and hearing examination
Otoscopy and indicated hearing tests check for wax, eardrum perforation or middle-ear conditions affecting the protocol.
Infrared goggles and calibration
The goggles are fitted comfortably and calibrated while you look at a visual target.
Oculomotor recordings
You follow stationary and moving lights during gaze, saccade, pursuit and optokinetic tasks.
Head and body positions are assessed
The clinician guides you into selected positions, including Dix-Hallpike where clinically appropriate.
Caloric testing when suitable
Each ear may be stimulated separately. A brief spinning sensation may occur and usually settles quickly.
Recordings are reviewed
Eye traces, nystagmus, positional patterns and caloric calculations are interpreted with the clinical history.
Report and treatment plan
Findings are explained in Hindi or English. The next step may include repositioning, rehabilitation or medical referral.
How to prepare for your VNG test
Correct preparation improves recording quality and can make the appointment more comfortable.
What you should do
- Eat a light meal approximately two hours before testing.
- Ask your doctor whether vertigo medicines should be paused.
- Bring previous prescriptions, hearing reports and scans.
- Wear spectacles instead of contact lenses.
- Bring a family member or friend if possible.
- Arrive approximately ten minutes early.
What you should avoid
- Do not stop essential medicines without medical approval.
- Avoid alcohol for 48 hours unless instructed otherwise.
- Avoid caffeine, tobacco and nicotine on the test morning.
- Do not wear mascara, kajal, eyeliner or contact lenses.
- Avoid oily products around the eyes or forehead.
- Do not arrive severely sleep-deprived.
Inform the clinic if you have an eardrum perforation, active ear discharge, recent ear surgery, pregnancy, serious neck or back pain, or another condition requiring a modified protocol.
VNG report and interpretation
Your report may contain eye-movement traces, velocity measurements and caloric calculations interpreted with your symptoms and history.
| Example finding | Possible interpretation | Common next step |
|---|---|---|
| Torsional-upbeating nystagmus during Dix-Hallpike | Posterior-canal BPPV | Epley maneuver or canal-specific treatment |
| Horizontal nystagmus during the supine roll test | Horizontal-canal BPPV | Barbecue-roll or Gufoni-type maneuver |
| Significant unilateral caloric weakness | One-sided vestibular hypofunction | Clinical correlation and vestibular rehabilitation |
| Low responses from both ears | Possible bilateral hypofunction | Further assessment and balance retraining |
| Abnormal saccades, pursuit or fixation suppression | Possible central involvement | Medical or neurological referral when indicated |
| Normal VNG despite continuing symptoms | Another cause may be present | Consider migraine, PPPD, cervical or medical assessment |
A VNG report should not be interpreted in isolation. Results must be correlated with symptoms, examination and medical history.
Typical VNG reference values
Exact ranges differ according to equipment, stimulus settings, laboratory protocol and patient age.
| Parameter | Typical reference | Important note |
|---|---|---|
| Spontaneous nystagmus | Below approximately 4–6°/s | Direction and fixation also matter |
| Gaze-evoked nystagmus | Generally absent | Medication and fatigue may affect results |
| Saccade latency | Approximately 150–250 ms | Attention and age influence latency |
| Saccade accuracy | Approximately 80–120% | Persistent under- or overshoot requires interpretation |
| Smooth-pursuit gain | Often above 0.8 at low frequencies | Age and test frequency affect gain |
| Caloric unilateral weakness | Usually below 20–25% | Use the laboratory’s validated cut-off |
| Directional preponderance | Usually below 26–30% | This value is less strongly localising |

ENG vs VNG and other balance tests
Each test examines a different part or frequency range of the balance system. They often complement rather than replace one another.
| Test | What it measures | Useful for | Limitation |
|---|---|---|---|
| VNG | Eye movements using infrared video | BPPV, vestibular asymmetry and central screening | Does not assess every vestibular organ |
| ENG | Eye-movement signals using electrodes | Alternative where video testing is unavailable | Cannot directly record torsional movement |
| vHIT | High-frequency vestibulo-ocular reflex | Rapid semicircular-canal assessment | Does not replace positional VNG |
| VEMP | Otolith and vestibular-nerve responses | Selected otolith and nerve disorders | Depends on protocol and middle-ear health |
| Audiometry | Hearing thresholds | Hearing loss and Ménière’s-related symptoms | Does not directly measure balance |
| MRI or CT | Structural anatomy | Selected neurological concerns | Normal imaging does not exclude vestibular dysfunction |
