What Is a VNG Test?

Videonystagmography (VNG) is the internationally recognised gold-standard diagnostic test for evaluating how well your inner ear and brain coordinate balance. At Care of Balance Speech & Hearing, located at Gauri Shankar Complex, behind Domino's Pizza, Kankarbagh, Patna – 800020, this test is performed by Dr. Abhijeet Kumar (B.ASLP, M.ASLP, former audiologist at IGIMS Patna and AIISH Mysuru, RCI Reg. A74216).

The VNG uses lightweight infrared goggles fitted with high-resolution cameras to precisely track involuntary eye movements called nystagmus. These eye movements are directly linked to your vestibular (balance) system. By analysing the pattern, speed, and direction of nystagmus during a series of controlled tasks, the audiologist can determine whether your dizziness originates from the inner ear, the vestibular nerve, or a central (brain-related) cause.

The test is completely non-invasive, painless, and takes approximately 1.5 to 2 hours. It does not require any injections or sedation. Your report is prepared and explained on the same day, in Hindi or English.

⚠ When to Seek Urgent Medical Help

If you experience sudden severe vertigo with slurred speech, facial numbness, double vision, difficulty walking, or severe headache — go to the nearest emergency room immediately. These may be signs of a stroke, not an inner-ear problem.

When Should You Get a VNG Test?

Many patients delay testing, hoping dizziness will resolve on its own. We recommend a VNG evaluation if you have experienced two or more of the following symptoms persistently:

Room Spinning

High Priority

Feeling that you or your surroundings are spinning — even when perfectly still. Classic sign of vestibular dysfunction.

Dizziness on Lying Down

BPPV Marker

Head spins when you lie down, sit up, or roll over in bed — hallmark symptom of Benign Paroxysmal Positional Vertigo.

Loss of Balance

Fall Risk

Feeling unsteady while walking, drifting to one side, or constant fear of falling — especially dangerous in elderly patients.

Tinnitus + Dizziness

Inner Ear

Ringing or buzzing in the ears combined with episodes of dizziness — may indicate labyrinthitis or Meniere's Disease.

Nausea with Vertigo

Acute Episode

Dizziness accompanied by nausea or vomiting — common during acute vestibular episodes and requires proper evaluation.

Recurring Episodes

Chronic

Repeated dizziness affecting daily life, work, sleep, and confidence — should not be ignored beyond 2 weeks.

Conditions a VNG Test Can Identify

VNG results help your specialist accurately diagnose the following vestibular and balance conditions for effective vertigo treatment in Patna:

BPPV (Benign Paroxysmal Positional Vertigo): Displaced calcium crystals in the inner ear causing position-triggered spinning. Most common vertigo cause — highly treatable with the Epley Maneuver.
Vestibular Neuritis: Inflammation of the vestibular nerve causing sudden, severe vertigo lasting days. VNG reveals unilateral caloric weakness.
Labyrinthitis: Inner ear infection affecting both hearing and balance. VNG combined with audiometry confirms the diagnosis.
Meniere's Disease: Recurrent vertigo attacks with hearing loss, tinnitus, and ear fullness. VNG helps track vestibular function over time.
Central Vestibular Disorders: Brain-related dizziness from stroke, tumour, or MS. VNG detects abnormal oculomotor patterns that signal a neurological referral.
PPPD (Persistent Postural-Perceptual Dizziness): Chronic dizziness without clear inner-ear findings. VNG helps rule out peripheral causes, guiding VRT treatment.
Bilateral Vestibulopathy: Reduced function in both inner ears. Caloric testing during VNG quantifies the degree of bilateral weakness.
Vestibular Migraine: Migraine-related dizziness that may not show clear VNG abnormalities but requires differential diagnosis with other vestibular conditions.

The Four VNG Sub-Tests

A complete VNG evaluation consists of four distinct assessments, each targeting a different aspect of your vestibular system:

Oculomotor

Tracks smooth eye movements as you follow a moving target on screen. Evaluates the central nervous system.

Positional

Records eye movements while you are placed in specific head and body positions. Detects BPPV and position-triggered vertigo.

Dix-Hallpike

The specialist moves your head through specific positions to provoke nystagmus — the gold-standard manoeuvre for BPPV.

Caloric Test

Warm and cool air gently delivered into each ear canal. Measures each inner ear's response independently.

Peripheral vs. Central Vertigo: Why VNG Matters

One of the most critical roles of VNG is distinguishing between peripheral (inner ear) and central (brain) causes of dizziness. The treatment approach is fundamentally different for each:

Peripheral Vertigo (Inner Ear)

Common Causes BPPV, Vestibular Neuritis, Labyrinthitis, Meniere's Disease.

VNG Findings Unilateral caloric weakness, fatiguing positional nystagmus, normal smooth pursuit.

Typical Treatment Epley Maneuver, vestibular rehabilitation, medication management — treated at our Kankarbagh clinic.

Prognosis Most cases are highly treatable, often resolving in 1–3 sessions or a few weeks of therapy.

Central Vertigo (Brain-Related)

Common Causes Stroke, acoustic neuroma, multiple sclerosis, brainstem lesions.

VNG Findings Direction-changing nystagmus, abnormal smooth pursuit, saccade deficits, gaze-evoked nystagmus.

Typical Treatment Urgent neurological referral, MRI, specialist management. VNG documentation provided for referral.

Prognosis Varies by cause. Early detection through VNG is critical for timely intervention.

Your Visit: Step-by-Step VNG Procedure

Here is exactly what happens during your VNG test at our Kankarbagh clinic — no surprises:

Check-in & Case History

You arrive at the clinic. The audiologist reviews your symptoms, medication history, and any previous test reports.

~15 minutes

Goggles Fitting & Calibration

Lightweight infrared VNG goggles are placed over your eyes. The cameras are calibrated to accurately track your eye movements in complete darkness.

~5 minutes

Oculomotor Evaluation

You follow a moving dot on a screen. The system records smooth pursuit, saccades, and optokinetic responses to check central function.

~15 minutes

Positional & Dix-Hallpike Tests

The specialist guides you through various head and body positions, including the Dix-Hallpike manoeuvre, while the goggles record eye movements for BPPV detection.

~20 minutes

Caloric Testing

Warm and cool air is gently introduced into each ear. This tests each inner ear's response independently. You may feel brief, mild dizziness — it passes quickly.

~30 minutes

Rest & Recovery

After the caloric sub-test, you rest comfortably for a few minutes until any residual dizziness settles completely.

~10 minutes

Same-Day Report & Counselling

Dr. Abhijeet Kumar reviews the results with you in simple language (Hindi or English), explains the diagnosis, and discusses the recommended treatment plan.

Understanding Your VNG Report

Dr. Abhijeet Kumar will explain every detail in Hindi or English. Here is a quick reference guide to common VNG findings:

Finding	Status	What It Means	Next Steps
Symmetric caloric responses	Normal	Both inner ears responding equally — no peripheral weakness detected.	Reassurance; explore other causes if symptoms persist.
Unilateral weakness (>25%)	Attention	One inner ear responding significantly less than the other.	May indicate vestibular neuritis or labyrinthitis. Treatment plan discussed same day.
Direction-changing nystagmus	Referral	Eye movements change direction with gaze — suggests possible central cause.	Neurological referral recommended; MRI may be advised.
Positional nystagmus (fatiguing)	Attention	Nystagmus triggered by head position that fades after a few seconds.	Classic BPPV pattern. Epley Maneuver often resolves it in 1–3 sessions.
Abnormal smooth pursuit	Attention	Eyes cannot smoothly follow a moving target — may indicate central involvement.	Further evaluation recommended; medication review.
