VORTEQ is available as an option on the VisualEyes VNG or as a stand-alone VORTEQ system. With the VNG, the AHR/VHIT/DVAT tests are integrated into the VNG test protocol for a comprehensive evaluation of the dizzy patient. As a stand-alone unit the Vorteq system becomes a more portable clinical tool. To help identify spontaneous or congenital nystagmus, a billable gaze nystagmus test is included with the Vorteq.


VORTEQ™ quickly analyzes the Vestibular Ocular Reflex (VOR) in patients with vertigo or balance disorders providing quantitative test results. Vorteq tests include video head impulse, dynamic visual acuity, and active head rotation VOR. All six semi-circular canals are evaluated for correct function of the inferior and superior vestibular nerves and the integrity of the vestibular end organs.

Binocular high speed (150 to 250Hz) eye video recordings (both eyes simultaneously) are not affected by a prosthetic eye, a lazy eye, a cataract in one eye, or blindness in one eye since the “good” eye can be still be recorded.

The Micromedical goggles are comfortable and light weight (10.2oz). They hug the bony structure of the face and thus stay in place during head thrusts. A goggles mounted angular velocity sensor (gyroscope) accurately measures head velocity. Clinical software notifies the examiner if a correct thrust velocity and acceleration were applied in VHIT and DVAT tests.
