Indications for Use
NeuroSwift Pro is intended for Viewing and recording eye movements in support of identifying vestibular disorders.The system is to be used by trained healthcare personnel in an appropriate healthcare setting. This system provides no diagnosis and does not provide diagnostic recommendations. The target population is 12+ years of age.
Device Story
NeuroSwift Pro (NS01-2) is a binocular video nystagmograph system consisting of see-through goggles with infrared (IR) cameras and software. Used by trained healthcare personnel in clinical settings to record and display eye movements. Hardware includes IR LEDs (940 nm), head strap, face cushion, and USB interface. Software records eye movement videos while displaying visual targets (stationary spots, moving targets, checkerboard patterns) on a computer screen. Clinician performs tests (gaze, saccade, pursuit, optokinetic, positional) while patient follows targets. Software measures slow phase velocity, eye position shift, and trace. Output includes eye movement traces, velocities, and analytical data for clinician review to support vestibular disorder identification. Device provides no automated diagnosis.
Clinical Evidence
Comparative performance study with 10 subjects evaluated by two professionals using both subject and predicate devices. Primary endpoints included calibration, eye movement direction, and quantitative metrics analyzed via Deming regression (95% CI). Results demonstrated equivalent performance across all tested vestibular functions (calibration, spontaneous nystagmus, gaze, saccade, pursuit, optokinetic, positional), meeting all pre-specified acceptance criteria.

Device Description The NeuroSwift Pro is intended for viewing and recording eye And Technology movements in support of identifying vestibular disorders. The Characteristics system is to be used by trained healthcare personnel in an appropriate healthcare setting. This system provides no diagnosis and does not provide diagnostic recommendations. NeuroSwift Pro. model NS01-2 contains goggles and software. The NeuroSwift Pro is a combination of hardware and software, designed to provide information for clinicians as a supplement in clinical decision-making by eye movements. The NeuroSwift Pro goggle is a see-through binocular video goggle with a pair of light reflectors and 3 metered, nylon braided USB cable connecting to the computer interface. Accompanying components include a stable and sturdy head strap, face cushion, and a lightweight eye cover. The hardware provides high-definition video recording capability. The NeuroSwift Pro software is a computer interface designed to record eye movement videos and simultaneously display the visual target(s) on the
{4}------------------------------------------------
computer screen. The software provides vestibular test modes and calibration functions. Initially, the software instructs the users to follow calibration functions. Then, the examiner can observe spontaneous nystagmus using the eye cover. The examiner can perform oculomotor tests with the goggles, while the patient follows visual targets on the screen. During gaze tests, the patient will fixate on stationary white spots that are positioned at center, right, left, up and down. In saccade tests the patient is asked to stare at the target moving in horizontal, vertical, or mixed pattern. In pursuit tests the patient's ability to track a target that moves in a sinusoidal or triangular pattern across the screen. The optokinetic function provides a large moving checkerboard pattern on the screen. Patients can change in various body positions as directed by the clinician. The software measures the eye movement via slow phase velocity and measures the eye position shift and trace. The recorded video and test protocols are processed in the NeuroSwift Pro software. The NeuroSwift Pro generates the traces of eye movements, eye velocities, and analytical data, which allows the clinician to determine the response of the patient according to the test functions.
The device contains the following vestibular test protocols:
- Calibration -
- Spontaneous nystagmus test -
- -Gaze test
- -Saccade test
- Pursuit test -
- Optokinetic test -
- Positional test -

Evaluation was completed following above standards and documents. Conformity to these standards demonstrates that the proposed subject device met the standards' established acceptance criteria for the device. This supports substantial equivalence to its predicates.
### Clinical Performance A performance comparison test was conducted to support the Testing substantial equivalence of the subject device. For this test, two experienced healthcare professionals (Evaluators) were recruited to evaluate the vestibular functions of 10 subjects using both the subject device and a legally marketed device (predicate device).
{10}------------------------------------------------
During the test, each subject underwent one round of testing with the subject device and another round of testing with the predicate device. The evaluators were responsible for observing the eye movements, generating test reports for each vestibular function test, and comparing the results between the two devices. The data analyzer utilized the Deming regression method (95% CI) to analyze and plot the data for comparison. The evaluators then assessed and rated the "Pass/Fail" status for all criteria of all tested subjects, including the calibration ability, eye movement direction, and Deming regression results. The test results successfully met all pre-specified acceptance criteria, demonstrating the equivalent performance between the subject device and the predicate device.

| Calibration | same |
| Spontaneous nystagmus | same |
| Gaze | same |
| Saccade | same |
| Pursuit | same |
| Optokinetic | same |

- Conclusion: The verification and validation testing, NeuroSwift Pro meets the pre-specified acceptance criteria, that are considered essential for its intended use and is considered substantially equivalent to the predicate device.
