What is the Videonystagmography Test?

VNG is used to find out if there is a disorder in the vestibular system (balance structures in your inner ear) or the part of the brain that controls balance.

What is Videonystagmography?

Complaints of dizziness (vertigo) and feeling of imbalance are quite common in our society.
We use videonystagmography (VNG) in our dizziness and balance laboratory to determine the diagnosis correctly and plan the appropriate treatment after a detailed ear, nose and throat examination. VNG is a test that measures involuntary eye movement called 'nystagmus'. These movements can be slow or fast, steady or jerky.
Your vestibular system includes the organs, nerves, and structures found in your inner ear. It is the main balance center of your body. The vestibular system works with your eyes, sense of touch, cerebellum and brain. Your brain communicates with different systems in your body to control your balance.
Vestibular disorder symptoms; If you feel dizzy, unsteady, or lose balance, you may need a VNG test. It is also a guide in terms of diagnosis in the complaints of ringing in the ears, fullness or pressure sensation accompanying dizziness. Special goggles are worn during the
VNG test. The glasses have a camera that records eye movements, and VNG has three main parts.

• Ocular tests (in which moving and non-moving points are tracked on the light bar)
• Positional tests (moving your head and body in different positions)
• The caloric test (done with warm and cold air in each ear)

The test may cause dizziness for a few minutes. If the dizziness persists for longer, you may want to get someone to help drive you home.
