OUR EYE-TRACKING SYSTEM FOR NEURO-OTOLOGY DIAGNOSTICS: THE INTERACOUSTICS EYESEECAM vHIT
IN-DEPTH DIAGNOSIS OF BALANCE DISORDERS VIA HEAD IMPULSE TESTS
Together with our partner Interacoustics, we have developed a special version of the EyeSeeCam that can be used to examine disorders of the vestibular system quickly, precisely and reliably. The Interacoustics EyeSeeCam vHIT is optimized for video-based head impulse testing.
Horizontal and vertical head impulse test (vHIT)
During a head impulse test, the Interacoustics EyeSeeCam vHIT measures the vestibulo-ocular reflex (VOR) during sudden and rapid head movement. Disorders of the vestibular organ in the inner ear can be tested in all three semicircular canal planes (horizontal, LARP, RALP). The camera captures eye and head movements simultaneously and in real time, providing immediate feedback on the measurement.
THE GOGGLES – HIGH-QUALITY DESIGN FOR MEANINGFUL TESTS
Lightweight non-slip goggles
The Interacoustics EyeSeeCam vHIT goggles are extremely lightweight, flexible and non-slip. Thanks to their perfect fit, the vestibulo-ocular reflex can be recorded accurately and reliably during head impulse tests, all but eliminating errors of measurement. These goggles not only sit securely, they are also comfortable to wear.
Swappable monocular camera
A monocular ball-and-socket joint camera captures the function of eye movements during head impulse tests. Thanks to the modular video camera, right and left eyes can be tested individually. Recorded measurements can be played back at a later time via the integrated video functionality.
HOW-TO-MANUAL AND 3D MODEL FOR YOUR ASSISTANCE
Guidelines for testing and diagnostics
The accompanying Interacoustics EyeSeeCam vHIT manual contains precise recommendations on the acceleration and direction of the head impulses as well as precise information on the reliability of the measured values and their suitability for diagnostic purposes.
A 3D model with an anatomical representation of the semicircular canals provides additional real-time guidance during the head pulses.
