Intended Use

The EyeSeeCam vHIT is designed to provide information on the performance of the vestibular ocular reflex (VOR) by providing objective measures of eye-velocity response to head-velocity stimulus, showing the VOR gain in the plane of rotation of the head.

Device Story

EyeSeeCam vHIT is a vestibular analysis system for assessing VOR in patients with dizziness. System components: head-mounted silicone goggle, monocular IR camera, calibration laser, and PC software. Operation: clinician performs head impulses; IMU (accelerometer/gyroscope) in camera housing records head angular velocity; IR camera records eye movements in darkness. Data processed on PC to calculate VOR gain (eye-velocity vs. head-velocity). Output: Velocity Regression Plot and Gain Plot. Clinician uses results to identify vestibular disorders. Benefits: quick, objective assessment of side-specific vestibular function.

Clinical Evidence

Clinical testing compared EyeSeeCam vHIT results against the predicate device (VORTEQ). Results demonstrated compliance and substantial equivalence between the two instruments. No specific sensitivity/specificity metrics provided; verification and validation activities confirmed device performance as specified.

Technological Characteristics

System includes head-mounted silicone goggle, monocular IR camera, and IMU (accelerometer/gyroscope). Connectivity: USB to PC. Calibration: head-mounted laser. Standards: IEC 60601-1, ANSI/AAMI ES60601-1, IEC 60601-1-2, IEC 62471-1, IEC 60825-1. Sampling rate: 220Hz. Software-based analysis of VOR gain.

Indications for Use

Indicated for patients experiencing dizziness or balance problems to assess vestibular ocular reflex (VOR) performance via objective measurement of eye-velocity response to head-velocity stimulus. Intended for use by trained personnel including audiologists, ENT surgeons, neurologists, and hearing healthcare professionals.

Device Description

vHIT is intended to be used as a quick and objective measurement of the vestibular ocular reflex (VOR) in response to head movements in the natural range of daily motions. The results will yield immediate information regarding side-specific vestibular function. EyeSeeCam vHIT allows the healthcare professional to efficiently assess the "dizzy" patient and quickly decide if the dizziness the patient is experiencing is related to a vestibular disorder.

The EyeSeeCam vHIT system consists of a head mounted goggle/mask, a camera unit with calibration laser and a software application running on a standard PC.

The vHIT goggle generally has one camera (monocular) fixed at the top side(s) of the mask. The camera is held in place mechanically with a spherical ball-and-socket joint. The vHIT goggle has support for camera position-for the left and for the right eye. Therefore the camera is interchangeable between the left and right eyes.

The vHIT goggle supports the camera that is used to record the eye images. This constitutes the major component of the vHIT system.

The USB camera uses infrared light (IR), which is not visible to the naked eye. The IR illumination enables sessions to be performed in complete darkness.

The vHIT goggle has dichroic mirrors that allow visible light to pass through and infra red light to be reflected towards the cameras.

A calibration laser is placed in the center of the goggle. This is used for camera / pupil calibration before testing.

The complete system is operated from a standard PC/Laptop via a standard USB connection. The PC application software controls the camera recordings and shows the results of the tests.

EyeSeeCam utilizes an inertial measurement unit (IMU) which is an accelerometer and gyroscope combined. The IMU is contained inside the camera unit. The camera housing is attached to a light weight goggle. The camera records eye movements and the IMU records an electronic waveform that is proportional to head angular velocity (deg/sec).

#### EyeSeeCam vHIT

#### Discussion, Similarities in indications for use

The vestibulo-ocular reflex (VOR) is a reflex eve movement that stabilizes images on the retina during head movement by producing an eye movement in the direction opposite to head movement, thus preserving the image on the center of the visual field. For example, when the head moves to the right, the eyes move to the left and when the head moves up the eyes move down. The indication for use for EyeSeeCam includes a slightly more detailed description of the same head impulse test procedure used to measure the VOR - including the canal tested is in the direction of the head movement - this includes both vertical and horizontal VOR test described by VORTEQ is certainly capable of testing both horizontal and vertical canals, it just doesn't specify which canals are tested in the intended use statement.

#### Summary of similarities

We appraise that slightly different technologies have been used in the two products (e.g. USB or Firewire / one or two cameras) but the functionality is ascertained to have the same purpose.

#### Discussion of differences

We did not find any essential or major differences between the two devices.

#### Verification and validation summary

We have verified EMC, safety and software performance. We have performed clinical comparisons between the EyeSeeCam and VORTEQ. We have reviewed the literature for articles about vestibular testing with vHT. All these activities, testing and validation show that EyeSeeCam vHIT performs as specified and is safe and effective.

#### Conclusion

We have compared key issues for the EyeSeeCam vHIT and the predicate device VORTEQ. We have performed a comparison validation between EyeSeeCam and VORTEQ. All similarities and differences have been discussed. We trust that the results of these comparisons demonstrate that the EyeSeeCam vHIT is substantially equivalent to the marketed predicate device.

Any deviations between EyeSeeCam vHIT and predicate devices are appraised to have no adverse affect on the safety and effectiveness of the device.
