Video-oculography (VOG) is a widely used and accepted method to track and analyze eye movements, particularly for neuro-otologic and balance testing. Building on recent technological advances, Neuro Kinetics, Inc. (NKI) has produced a new video-oculography system that delivers accurate, affordable, 4-dimensional eye measurement and analysis. With Neuro Kinetics' I-Portal^® system, a wider range of clinicians and researchers have the opportunity to improve diagnoses and increase understanding of both the vestibular and ocular-motor systems.

I-Portal^® VNG delivers improved accuracy and precision, torsional eye tracking, an affordable price, and easy-to-use VEST™ software.

All components of the Neuro Kinetics' clinical testing system are controlled by VEST™ software, VNG Edition, and run on Windows^® XP. Preset protocols prompt the operator through a series of tests, and at the click of a button a web-enabled report is available for patient files and insurance documentation. VEST™ software includes all the standard and reimbursable VNG tests with software upgrades available for Subjective Visual Vertical and Horizontal, and Dynamic Visual Acuity Testing (available in mid 2007).
