If you are looking for the best VNG test in Dhaka because of repeated dizziness, vertigo, imbalance, or unexplained spinning sensations, choosing the right diagnostic center is important. A proper vestibular assessment can help doctors understand whether your symptoms may be related to the inner ear, vestibular system, or other balance pathways.
Videonystagmography (VNG) is a specialized test that records eye movements while different visual and positional tasks are performed. These eye movements can provide useful information about how the balance system is working. VNG is commonly used as part of the evaluation of patients with vertigo, dizziness, and balance disorders.
If you want to learn more about the test itself, you can read our detailed VNG Test Theory page.
What Is a VNG Test?
VNG stands for Videonystagmography. It uses specialized video goggles to record eye movements during different parts of the examination.
The vestibular system in the inner ear works together with the eyes and brain to help maintain balance. When there is a problem in this system, abnormal eye movements called nystagmus may occur. VNG allows these movements to be recorded and analyzed.
A VNG test may include eye movement testing, positional testing, and caloric testing when clinically indicated. The results are interpreted together with the patient’s symptoms, medical history, and clinical examination.
Who May Need a VNG Test?
A VNG test may be recommended when a patient has symptoms such as:
- Recurrent or persistent vertigo
- Unexplained dizziness
- Balance problems
- Feeling that the room is spinning
- Difficulty walking steadily
- Suspected vestibular weakness
- Certain inner-ear balance disorders
- Dizziness with abnormal eye movements
- Symptoms that require further vestibular evaluation
However, VNG is not automatically required for every person with dizziness. Vestibular tests should be selected based on the patient’s symptoms and clinical assessment.

What Happens During a VNG Test?
During VNG testing, the patient usually wears video goggles that contain cameras to track eye movements.
Depending on the clinical requirement, the test may involve:
1. Eye Movement Testing
The patient follows visual targets while the equipment records eye movements. This can provide information about oculomotor function.
2. Gaze Testing
Eye movements are observed while looking in different directions. Abnormal eye movements can provide important information for further evaluation.
3. Positional Testing
The patient’s head and body are placed in different positions while eye movements are monitored. This can help identify positional nystagmus and support the assessment of certain vestibular conditions.
4. Caloric Testing
When indicated, caloric stimulation is used to evaluate vestibular function in each ear. Some people may experience temporary dizziness or nausea during this part of the examination. These symptoms generally settle shortly after the test.
Why Choose a Specialized VNG Test Center in Dhaka?
The quality of a vestibular test is not only about the equipment. Proper patient assessment, correct test selection, professional supervision, and appropriate interpretation are also important.
A specialized vertigo and balance center can evaluate your symptoms and determine whether VNG or another vestibular test is appropriate.
At Vertigo & Balance Center, specialized assessment is focused on vertigo, dizziness, balance disorders, and vestibular conditions. The center provides vestibular diagnostic services and specialist care in Dhaka.
VNG Test vs vHIT: What Is the Difference?
VNG and vHIT are different vestibular tests.
VNG evaluates eye movements through a broader test battery that may include oculomotor, positional, and caloric components. vHIT evaluates the vestibulo-ocular reflex during rapid head movements and can assess the function of individual semicircular canals.
These tests are not necessarily alternatives. Depending on the patient’s symptoms, a specialist may recommend one test or more than one test to obtain a clearer picture of vestibular function.

Is VNG Test Safe?
VNG is a non-invasive diagnostic test. It does not require surgery or needles.
Some patients may experience temporary dizziness or nausea, particularly during caloric testing. The test can be paused if the patient becomes uncomfortable.
Your doctor or testing center may also provide specific instructions before the examination. Depending on the test protocol, patients may be asked about medications, alcohol intake, meals, contact lenses, or eye makeup before testing. Always follow the instructions provided by your healthcare professional.
How Long Does a VNG Test Take?
The exact duration can vary depending on the test protocol and the number of components required.
A complete VNG assessment may take approximately 45–60 minutes when multiple components are included. Your testing time may be different depending on your clinical requirements.
Does Everyone With Vertigo Need a VNG Test?
No. VNG should not be treated as a routine test for everyone with vertigo.
For example, some patients with typical BPPV can be diagnosed clinically using appropriate positional testing, and additional vestibular testing may not be necessary unless there are other symptoms or findings.
This is why a specialist assessment before testing is important. The right test depends on the patient’s symptoms, history, examination findings, and suspected condition.
What Can VNG Results Tell You?
VNG results may provide information about:
- Abnormal eye movements
- Positional nystagmus
- Oculomotor abnormalities
- Vestibular asymmetry
- Possible peripheral vestibular dysfunction
- Findings that may require further neurological or vestibular evaluation
A VNG result should not be interpreted by itself. Doctors consider the test findings together with symptoms and other clinical information before making a diagnosis or treatment plan.
