Video Nystagmography (VNG) – NeuroEquilibrium International

Vestibular and oculomotor evaluation

Advanced Video Nystagmography (VNG)

NeuroEquilibrium VNG uses advanced eye-tracking technology with infrared cameras to evaluate the vestibular and oculomotor systems. The equipment eliminates contamination by myogenic and electrical noise seen in ENG.

Evaluation protocols

NeuroEquilibrium Video Nystagmography evaluates peripheral and central vestibular functions through the following protocols:

Spontaneous nystagmus

Caloric tests

Oculomotor tests

Gaze evoked nystagmus

Smooth tracking

Saccades

Skew deviation

Optokinetic test

Induced nystagmus

Positional test

Valsalva induced nystagmus

Hyperventilation induced nystagmus

Head shaking test

Intelligent software

Advanced eye tracking algorithm

Automatic calculation of slow phase velocity, canal paresis and fixation index in caloric test

Advanced algorithm to generate random saccades and remove anticipated saccades

Generates smooth pursuit at varying frequencies

Automatically generates graphs of all parameters with easy visual comparison with normative data

Industry-leading binocular goggle design

Binocular eye recording

No adjustment required for focus or mirror setting

Lightweight with direct USB connection to a laptop or desktop computer

Easy-fit magnetic cover allowing both occluded and unoccluded measurements

Built-in fixation light

Enhanced image quality through a high-frame-rate camera

Hot mirror to view the eye in the primary ocular axis. It allows eye imaging to be aligned within ±10° of the primary ocular axis to minimise parallax.
