Videonystagmoscope
(VNS)

Looking through the eyes to understand dizziness.

VNS is a diagnostic tool that uses infrared video goggles to directly observe and analyze eye movements in real time. Since the eyes and inner ear are functionally linked, monitoring these movements helps determine whether a patient’s dizziness or imbalance is related to peripheral vestibular dysfunction or central causes.

What it’s
used for

All vertigo cases including Benign Paroxysmal Positional Vertigo (BPPV), Vestibular neuritis or labyrinthitis, vestibular migraine, endolymphatic hydrops, Persistent Postural-Perceptual Dizziness (PPPD), Meniere’s disease, unilateral or bilateral vestibular weakness etc…
Differentiation between central and peripheral vestibular disorders
Unexplained dizziness or imbalance

Why it
works

When there is a dysfunction in the inner ear, the eyes often respond with compensatory movements. VNS allows us to detect involuntary eye movements (nystagmus) during specific head or body maneuvers, providing insights into the underlying vestibular pathology.

What to
expect

The patient wears infrared video goggles while seated and performs a series of guided head and body movements such as lying down, turning, or shaking the head. These tests are designed to provoke and observe nystagmus. The procedure is non-invasive and typically takes between 10 to 20 minutes, depending on the individual case.

Why clients
love it

VNS offers immediate visual feedback and objective data that help patients better understand the nature of their condition. This clarity often brings reassurance and allows us to create a targeted and personalized treatment plan based on clinical findings.
