Intended Use
The Orion rotary chair is an optional accessory for VisualEyes 525/VisualEyes 515 eye movement recording systems. 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 VisualEyes system is 5 years of age and above.
Device Story
Orion rotary chair is an accessory for VisualEyes 515/525 vestibular examination systems. It facilitates vestibular ocular reflex (VOR) testing by rotating the patient. Variants include Reclining (for caloric/positional/Dix-Hallpike tests), Auto Traverse, and Comprehensive (includes dark room enclosure, XY laser projector, optokinetic drum, and subjective visual vertical testing). Operated by trained medical professionals in clinical settings. The chair integrates with software that records and measures eye movement images from goggle-mounted cameras. Output assists clinicians in diagnosing vestibular disorders. Safety features include an electronic lock (Reclining model) to immobilize the chair during patient entry/exit and testing. The device replaces the System 2000 predicate, utilizing updated hardware and USB connectivity for goggles.
Clinical Evidence
No clinical tests were performed. Substantial equivalence is supported by non-clinical performance testing, including bench testing and validation comparisons between the Orion chair variants and the predicate System 2000 device to ensure specified performance, safety, and effectiveness.
Technological Characteristics
Rotary chair system with three variants (Reclining, Auto Traverse, Comprehensive). Features include motorized rotation, electronic locking mechanism, XY laser projector, and optokinetic drum. Connectivity via USB for video goggles. Operates within 0.01-0.64 Hz frequency range. Maximum step velocity 200-350 deg/sec; maximum acceleration 100-200 deg/sec2. Supported by VisualEyes 515/525 software.
Indications for Use
Indicated for patients 5 years of age and older undergoing nystagmographic evaluation for the diagnosis and documentation of vestibular disorders.

### Equivalent discussions (Software)
The evaluation of the VisualEves 515/525 compared to Spectrum was included in the 510(k) submission cleared under K163149. The evaluation was done for the System 2000 rotational chair. The Orion chair hardware equivalency was established by setting tests in VisualEyes 515/525 to certain parameters and then physically measuring the chair performance.
### Equivalent discussions (Mechanical Foot Brake)
The ORION Reclining Chair implements an electronic lock. This function is designed to place the chair into an immobile state in order to ensure patient safety when seating and/or disembarking the patient from the reclining chair. It is also used to keep the chair immobile during the VNG test battery. The lock chair function is only made available prior to the test and cannot be activated during the testing procedure. This will automatically be switched off when performing a rotational chair test.
The System 2000 Reclining chair does not have an electronic braking system. A manual foot brake is found on the side of the chair drum. The operator should apply the brake to keep the chair in place for patient entry and VNG testing. When reclining the chair for Dix Hallpike, Positional, and Caloric tests, the foot brake should be released in order to rotate the chair if needed due to space constraints. The foot brake should then be reapplied when the chair is reclined to the appropriate position to keep the chair from rotating during the test.
Interacoustics A/S appraise that the function of the Mechanical Foot Brake and the electric lock is essential equivalent.

### Performance Tests
Interacoustics A/S appraise that there are only minor updates and changes to the devices and that the safety and efficiency are essential the same.
Interacoustics A/S have performed comparisons between the updated revision of Orion chairs and the predicate device. All these activities, testing and validation show that Orion chairs performs as specified and are safe and effective.
### Clinical tests
No clinical tests were performed. Interacoustics A/S have performed comparisons between the Orion chairs and the predicate device. These activities, testing and validation show that Orion chairs perform as specified and are safe and effective.
## Discussion of differences
Interacoustics A/S did not find any essential or maior differences between the predicate and subject devices. Any deviations between Orion chairs and predicate device are appraised to have no impact on the safety and effectiveness of the device.
#### Conclusion
Interacoustics A/S have compared key issues for the Orion chairs and the predicate device. Interacoustics A/S have performed a comparison validation between Orion chairs and the predicate device.
Based upon non-clinical and clinical performance testing, the Orion chairs were found to have a safety and effectiveness profile that is comparable to the predicate device. Therefore, Interacoustics A/S has demonstrated that the Orion chairs are substantially equivalent to the stated predicate device.
