EyeSeeCam Video Head Impulse Test (vHIT) has been launched by Interacoustics for quick and objective measurements of the vestibular ocular reflex (VOR).
The EyeSeeCam vHIT system comprises a light weight goggle with a high-frequency camera, head accelerometer, calibration laser and a laptop. Thanks to its no-slippage-goggle design, EyeSeeCam vHIT produces more accurate and reliable test results, and the flexible design allows for testing on left or right eye on a wide range of patients.
During data collection, eye and head movements can be viewed simultaneously in real time, and a practical “impulse guide” will help the user to adjust their impulses to the correct amplitude and velocity. EyeSeeCam vHIT features a comprehensive test report with instantaneous velocity measurements as well as velocity regression. The informative report displays both overt and covert saccades in 2D or 3D rotations as well as gain calculations @ 40, 60 and 80 ms.
