The device is designed to "assess the vestibular-ocular-reflex (VOR) by measuring, recording, displaying, and analyzing eye and head movements," which is a diagnostic function to determine the state of a physiological function.
No
The device description explicitly states it consists of a "remote camera" and a "built-in infrared illuminator," which are hardware components. The software processes data from this hardware.
Based on the provided information, the Synapsys VHIT device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The Synapsys VHIT device directly measures and analyzes eye and head movements of the patient in real-time. It does not involve the analysis of biological samples like blood, urine, tissue, etc.
- The intended use describes a direct assessment of a physiological reflex (VOR) by measuring physical movements. This is a functional assessment, not a diagnostic test performed on a specimen.
The device falls under the category of a medical device used for functional assessment and measurement, not an IVD.

Device Description
Synapsys VHT (Video Head Impulse Test) allows to assess the vestibular-ocular-reflex (VOR) by measuring, and analyzing eye and head movements. Synapsys VHT does not require the patient to wear goggles, since it consists of a remote camera placed 90 cm from the subject, framing the subject's eyes and head. The device features real-time eyes detection and tracking, thanks to a built-in infrared illuminator hat lights up the subject. Head displacements are retrieved using algorithms that extract motion data from real time images recorded by the camera.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The Synapsys VHT device underwent a comprehensive series of tests for its Verification, which included verification of all VHIT software and system requirements within their intended operating environment, covering functionality, performance, usability, safety and security.
A comparative analysis of VOR gain measurement has been conducted in Synapsys VHIT and ICS Impulse. Each device has been used, according to the information reported in their User Manual, to perform a test both on pathological and non-pathological patients. The primary emphasis of the analysis was to verify that the average VOR Gain computed by the two devices fell within a confidence interval of ±0.1. Secondary to this goal, trajectories were examined to assess whether similar patterns or behaviors. The results of the comparative analysis demonstrate that the VOR gain differences fall within the predefined confidence interval of ±0.1. Additionally, the consistency observed in the trajectories of head and eye movements during head impulse maneuvers further bolsters the case for their equivalence. The bench and comparative testing results confirm the substantial equivalence (SE) of the Inventis Synapsys VHT device with the predicate device Natus ICS Impulse.

Synapsys VHT does not require the patient to wear goggles, since it consists of a remote camera placed 90 cm from the subject, framing the subject's eyes and head.

Intended Use/Indications for Use 21 CFR 807.92(a)(5) The Synapsys VHIT is a medical device designed to assess the vestibular-ocular-reflex (VOR) by measuring, and analyzing eye and head movements. Indications for Use Comparison 21 CFR 807.92(a)(5) The Indications for Use of Synapsys VHIT device and the predicate device (ICS Impulse) are the same. Technological Comparison 21 CFR 807.92(a)(6)
Synapsys VHIT has different technological characteristics from the predicate device. Predicate device Natus ICS Impulse consists of head mount goggles which measure the velocity of the head through an accelerometric sensor, and frame eye movements thanks to an infrared camera mounted on the image of the eye reflected on a
5
siver mirror placed in front of the eye itself. The software, running on a PC connected to the Natus ICS Impulse device, performs eye detection on real time images recorded by the camera and combines this data with information coming from the accelerometric sensor. In contrast, Synapsys VHT device consists of an infrared remote-camera that frames the subjects face without the need for gogles, avoiding any contact between patient and device. The device lights up the subject's face, placed 90 cm from the camera, thanks to a built-in infrared illuminator. Synapsys VHT software, running on a PC connected to the device, measures eyes and head velocities using software algorithms for eye tracking and head pose estimation, based on analysis of real time images recorded by the camera. Moreover, while Natus ICS Impulse can track and analyze the right eye only, due to the infrared camera permanently fixed on the right side of the goggle, the Inventis Synapsys VHIT can record and analyze both eyes during lateral head impulses.
Both Synapsys VHIT and Natus ICS Impulse devices enable to perform Video Head Impulse Tests on Laterior and Posterior planes, allowing comprehensive assessment of all six semicircular canals. They also both provide the same clinical metrics, including VOR gain, head peak velocities, and quantitative data on detected covert saccades. Additionally, they display a range of informative graphs, such as an overall VOR Gain summary of the performed examination, time-based head and eye velocity traces for each maneuver, and a Gain vs. Head Peak Velocity graph.
Non-Clinical and/or Clinical Tests Summary & Conclusions 21 CFR 807.92(b)
The Synapsys VHT device underwent a comprehensive series of tests for its Verification. These tests included verification of all VHIT software and system requirements within their intended operating environment. The testing covered various aspects, including functionality, performance, usability, safety and security, ensuring that the Synapsys VHT device meets its defined software and system specifications.
The Synapsys VHIT device was further tested and validated according to the following standards:

In addition to the tests performed for Verification of System and Software requirements of Synapsys VHT device, a comparative analysis of VOR gain measurement has been conducted in Synapsys VHIT and ICS Impulse.
Each device has been used, according to the information reported in their User Manual, to perform a test both on pathological and nonpathological patients.
The primary emphasis of the analysis was to verify that the average VOR Gain computed by the two devices fell within a confidence interval of ±0.1. Secondary to this goal, we examined the trajectories to assess whether similar patterns or behaviors. The results of the comparative analysis demonstrate that the VOR gain differences fall within the predefined confidence interval of ±0.1.
This provides evidence that the devices are equivalent for clinical practice, in both pathological subjects.
Additionally, the consistency observed in the trajectories of head and eye movements during head impulse maneuvers further bolsters the case for their equivalence.
In conclusion, the bench and comparative testing results confirm the substantial equivalence (SE) of the Inventis Synapsys VHT device with the predicate device Natus ICS Impulse.
