Intended Use

The VisualEyes system provides information to assist in the nystagmographic evaluation, diagnosis and documentation of vestibular disorders. Nystagmus of the eye is recorded by use of a goggle mounted with cameras. These images are measured, recorded, displayed and stored in the software. This information then can be used by a trained medical professional to assist in diagnosing vestibular disorders. The target population for VisualEves system is 5 years of age+

Device Story

VisualEyes 505/515/525 is a software-based vestibular analysis system. It captures eye movement data via head-mounted video goggles equipped with cameras. The software processes these video inputs to measure, record, display, and store nystagmus data. Used in clinical settings by trained professionals (audiologists, ENT surgeons, hearing healthcare professionals), the system assists in diagnosing vestibular disorders by performing tests such as Spontaneous Nystagmus, Gaze, Smooth Pursuit, Saccade, Optokinetic, Dix-Hallpike, Positional, Caloric, SHA, Step, and Visual VOR. The output provides clinicians with objective documentation of eye movements, facilitating clinical decision-making regarding vestibular function. The system benefits patients by providing a non-invasive method for evaluating vestibular health.

Clinical Evidence

Clinical comparison validation performed. Side-by-side testing conducted on human subjects with conjugate eye movements, where one eye was processed by the predicate device and the other by the subject device. Results showed high correlation and equivalence between the subject device and predicates for nystagmus detection and analysis algorithms.

Technological Characteristics

System comprises head-mounted video goggles/mask, camera unit, and software running on a standard Microsoft Windows PC. Utilizes video-oculography (VOG) sensing. Software performs automated analysis of eye movements. Tests conform to ANSI S3.45 sections 5-9.

Indications for Use

Indicated for nystagmographic evaluation, diagnosis, and documentation of vestibular disorders in patients 5 years of age and older.

Regulatory Classification

Identification

# VIDEO EYE TRAKKER vs. VisualEyes

# Summary of IFU similarities

We appraise that the slightly different phrasing in the indications for use are the only deviation in the comparisons. The deviations are discussed above and appraised to be substantially equivalent and hence do not raise any issues regarding safety and efficiency

# Performance Tests

We presented a comparison of the subject device and the predicate devices to demonstrate that the key algorithms for detecting and analysing nystagmus were similar. The demonstration was carried out as a side by side comparison where the same patient was analysed by the subject device and the predicate device simultaneously. All tests were performed on test subjects with conjugate eye movements. This means that an eye movement on one eye will match the movement of the other eye. One camera recorded the left eye and was processed in the predicate device and the other recorded the right eye and was processed in subject device. All results showed equivalence between the predicates and the subject, this means that results processed in predicates are showing equivalence to results from the subject device.

{10}------------------------------------------------

#### Clinical tests

We have performed clinical comparisons between the three systems. These activities, testing and validation show that VisualEyes 505/515/ 525 perform as specified and is safe and effective.

### Discussion of differences

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

### Conclusion

We have compared key issues for the VisualEyes 505/515/ 525 and the predicate devices. We have performed a comparison validation between VisualEyes 505/515/ 525 and the predicate devices. All similarities and differences have been discussed. We trust that the results of these comparisons demonstrate that the VisualEyes 505/515/ 525 is substantially equivalent to the marketed predicate devices.

Any deviations between VisualEyes 505/515/ 525 and predicate devices are appraised to have no adverse effect on the safety and effectiveness of the device.
