In-Depth Analysis: The vHIT EyeSeeCam – A Key Tool for Vestibular Assessment
The vHIT EyeSeeCam, developed by Interacoustics, is a groundbreaking measurement system in the field of audiology and balance diagnostics. This system allows for rapid, objective, and non-invasive evaluation of the vestibulo-ocular reflex (VOR), a critical mechanism for stabilizing gaze during head movements. The device operates by recording simultaneous, real-time movements of the head and eyes. When a patient undergoes a head impulse, a healthy vestibular system maintains fixation on a target. In cases of vestibular dysfunction, the eyes perform a corrective movement, known as a saccade, to return to the target. The vHIT detects both visible and covert saccades and analyzes them with high accuracy.
The vHIT EyeSeeCam evaluates all six semicircular canals (lateral, RALP, and LARP) with advanced 3D modeling. This modeling provides an anatomically accurate representation of the canals, enhancing test reliability and improving data interpretation. The user interface displays data in an intuitive format, including gain values at 40, 60, and 80 ms, along with velocity regression curves, ensuring comprehensive VOR analysis.
The EyeSeeCam mask is designed to minimize motion artifacts. Its lightweight construction and integrated stabilizers keep it securely in place during testing. It is compatible with both the right and left eyes through interchangeable spherical cameras. The high-speed camera ensures precise eye movement tracking, while built-in laser markers allow for quick and accurate calibration in any clinical setting.
The vHIT EyeSeeCam also supports the SHIMP protocol, a complementary method for deeper vestibular function evaluation. The software offers customizable threshold suggestions, allowing clinicians to tailor diagnostics to each patient. Additionally, video recording and playback functionality enhance case review and training.
Interacoustics, known for its innovation, delivers with the vHIT a highly reliable and flexible tool suitable for everyday clinical use. It integrates seamlessly into a full suite of vestibular and audiometric solutions, making it an essential part of comprehensive patient diagnostics.
