Videonystagmography (VNG) is a diagnostic test that is used to evaluate patients with symptoms of dizziness, vertigo, and balance disorders. It is a non-invasive test that is performed in a Audio-vestibular clinic and is used to diagnose a wide range of conditions that can affect the inner ear and the balance system of the body.
VNG is a test that is performed by an audiologist (Spacially trained in Vestibular assesment), who will place a VOG goggle in the eyes and ask the patient to perform certain eye and head movements. The camera in the goggle will measure the eye movements of the patient, which are then analyzed by a computer to determine if there are any abnormalities in the inner ear or the balance system.
One of the most common conditions that VNG is used to diagnose is benign paroxysmal positional vertigo (BPPV). BPPV is a condition that causes brief episodes of vertigo or dizziness, usually when the head is moved in a certain position. VNG can help to diagnose BPPV by measuring the eye movements of the patient and determining if there is a specific pattern of eye movements that is associated with the condition.
VNG is also used to diagnose other inner ear conditions, such as Meniere’s disease, vestibular neuritis, and labyrinthitis. These conditions can cause symptoms such as dizziness, vertigo, and hearing loss, and VNG can help to diagnose these conditions by measuring the eye movements of the patient and determining if there are any abnormalities in the inner ear.
In addition to diagnosing inner ear conditions, VNG can also be used to evaluate patients with balance disorders. Balance disorders can cause symptoms such as dizziness, unsteadiness, and falls, and VNG can help to diagnose these conditions by measuring the eye movements of the patient and determining if there are any abnormalities in the balance system.
One of the benefits of VNG is that it is a non-invasive test that does not require any radiation or sedation. It is also a relatively quick test that can be performed in a hearing aid clinic, making it convenient for patients.
VNG is a test that is covered by most insurance plans, and it is usually recommended for patients with symptoms of dizziness, vertigo, and balance disorders. If you are experiencing any of these symptoms, please schedule an appointment with our hearing aid clinic, and an audiologist will be able to evaluate you and determine if VNG is the right test for you.
In conclusion, VNG is an important diagnostic test that is used to evaluate patients with symptoms of dizziness, vertigo, and balance disorders. It is a non-invasive test that is performed in a hearing aid clinic and is used to diagnose a wide range of conditions that can affect the inner ear and the balance system of the body. If you are experiencing any of these symptoms, please schedule an appointment with our hearing aid clinic, and an audiologist will be able to evaluate you and determine if VNG is the right test for you.
