Intended Use / Indications for Use
The EyeBOX is intended to measure and analyze eye movements as an aid in the diagnosis of concussion, also known as mild traumatic brain injury (mTBI), in patients 5 through 67 years of age in conjunction with a standard neurological assessment of concussion.
A negative BOX Score classification may correspond to eye movement that is consistent with a lack of concussion within one week of injury.
A positive BOX Score classification corresponds to eye movement that may be present in both patients with or without concussion within one week of injury.
The EyeBOX provides a set of eye-tracking metrics in relation to a reference database of uninjured individuals.
Summary of Technological Characteristics
- Eye-tracking is the technological principle for both the subject and predicate devices. The EyeBOX uses eye-tracking technology and a data processing algorithm to detect subtle changes in eye movements resulting from concussion. The eye tracking takes 220 seconds to complete, is non-invasive and involves watching a video move around the perimeter of an LCD monitor positioned in front of the patient while a high speed near-infrared (IR) camera records gaze positions 500 times per second. The data are analyzed automatically to produce one or more outcome measures in the form of a report. This report, in conjunction with other standard of care assessments, are used to aid in the diagnosis of concussion. A BOX score is the main diagnostic outcome measure and ranges between 0 and 20, with scores below 10 associated with lower risk of concussion and scores equal to or greater than 10 suggestive of possible concussion. The BOX Score may be used within one week of the known head injury. In addition to the BOX Score, a number of measurements are presented in relation to a normative database of uninjured individuals. The normative database allows physicians to compare ocular motor function of the patient being tested to the normal population. The measurements include pupil size and dynamics, saccades, horizontal/vertical disconjugacy, path departure from stimulus, average gaze displacement ("travel"), and blinks. The addition of more available eye tracking parameters does not raise new questions of safety or effectiveness, and the available testing demonstrates that the addition of these parameters does not adversely impact performance with respect to accuracy.
At a high level, the subject and predicate devices are based on the following same technological elements:
- The hardware for the EyeBOX Model EBX-4.0 and Model EBX 4.1 are exactly the same. This includes all components, and the form factor
- The algorithm for the BOX Score is exactly the same as the EyeBOX Model EBX-4.0
Page 7
Oculogica's EyeBOX uses eye-tracking technology and a data processing algorithm to detect subtle changes in eye movements resulting from concussion. The EyeBOX principles of operation have not changed. The principles of operation are identical to its predicate device. The technological characteristics important to device function as an aid in diagnosis of concussion are not changed; the eye tracking performance and proprietary EyeBOX algorithm, which processes the eye tracking data and outputs the BOX score, are not changed.
The following technological differences exist between the subject and predicate devices:
Output report changes, including:
- Additional eye-tracking and pupillometry metrics
- Inclusion of a reference database of healthy subjects
- Display "Not Computed" for spurious metric values
Upgrades to third party software components to remove cyber security vulnerabilities.
None of the changes in technology raise new questions of safety or effectiveness. The hardware provides the same functionality as the predicate. The inclusion of additional pupillometric metrics in the EyeBOX Model EBX-4.1 (i.e., pupil size, pupil dynamics) for contextual clinical information does not raise different questions of safety and effectiveness because both devices use multiple eye tracking parameters. Although the specific parameters measured by each device differ slightly, the fundamental principles and technological characteristics are similar, i.e., both use infrared-based eye-tracking at a high frequency and corneal reflection to measure pupil position. These differences in eye-tracking metrics are supported by performance testing based on acceptable methods that demonstrate the proposed device is as safe and effective as the predicate.

| Device Description | Oculogica's EyeBOX is an eye-tracking device with custom software. The device is comprised of a host PC with integrated touchscreen interface for the operator and patient stimulus, eye tracking camera, and separate head-stabilizing rest for the patient, and data processing algorithm. The data processing algorithm detects subtle changes in eye movements resulting from concussion. The eye tracking task takes about 4 minutes to complete and involves watching a video move around the perimeter of an LCD monitor positioned in front of the patient while a high speed infrared (IR) camera records gaze positions 500 times per second. The post-processed data are analyzed automatically to produce one or more outcome measures. | SyncThink's EYE-SYNCTM consists of two components. These components are provided as a system with preloaded software. The EYE-SYNC is a fully-integrated, head-mounted eye-tracking system with two primary system components: 1) the head mounted display, containing the eye-tracking hardware and software system; and, 2) an integrated handheld peripheral used to administer the test and store testing results. The eye tracking unit includes two high-speed infrared cameras connected to a dedicated image analysis computing system. Camera lighting is provided by 12 high quality Light-emitting Diodes (LEDs) centered at 850 nanometers. EYE-SYNC is a less than one minute, non-invasive eye-tracking test that provides a quantitative representation of attention using precise measurements of eye gaze position relative to a target stimulus. Eye gaze tracking is performed using a proprietary implementation of the pupil-corneal reaction method. Display and eye tracking are controlled using the attached Windows-based handheld. Batteries provide power for remote use (away from power source). As a subject tracks a predictable moving target that follows a circular trajectory on a screen within the head mounted system, eye gaze position and time stamp are recorded by the use of cameras in the head mounted system. Multiple eye gaze positions relative to the target stimulus are measured and analyzed for position error variability using installed software, and the results are displayed and stored on the handheld peripheral | Oculogica's EyeBOX is an eye-tracking device with custom software.
