An Early Prospective Study of the Traq™ Device for Characterization of Binocular Ocular Function in Normal Subjects and Subjects With Recent Traumatic Brain Injury (REB-001)

July 30, 2026 updated by: Rebiscan, Inc.
The early prospective study of Traq™ (an investigational binocular ophthalmic neurodiagnostic device) will measure binocular ocular functions (bilateral foveal fixation, foveal binocularity, and fovea-tracked saccadic latency) in normal subjects and those with history of mild-to moderate traumatic brain injury (mTBI).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

An initial, single-center, prospective, non-masked, non-randomized, parallel-arm clinical study designed to collect Traq™ measurement data from normal subjects (normal arm) and subjects with a history of mild to moderate traumatic brain injury (mTBI) within the last six months (post-TBI arm) to characterize binocular ocular function measurement outcomes across the two study populations.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Eye care clinic patients

Description

Inclusion Criteria:

  1. Age 12 years or older at the time of enrollment.
  2. Able to understand and sign an informed consent form (or with parent/guardian for subjects less than 18 years of age).
  3. Willing and able to complete all required study visits and test assessments.
  4. Subjects with no history of traumatic brain injury (normal arm).
  5. Subjects with a history of mild to moderate traumatic brain injury (mTBI) within the last six months, (post-TBI arm).

Exclusion Criteria:

  1. Concurrent participation in another drug or device clinical investigation.
  2. Subject with a history of eye disease which could reduce, or limit reflected polarized light from the retina, such as corneal scarring, cataract, glaucoma, degenerative retinal conditions (e.g., age-related macular degeneration, diabetic retinopathy), or other conditions which may decrease device signal reflectance.
  3. Subjects who are pregnant, planning to become pregnant, or are breastfeeding.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Device Metrics
Time Frame: Four individual scans through study completion: Day 0, Day 30, Day 60, Day 90.

A composite Traq score will be calculated on a scale of 0.00-to-2.00 at each visit. The score will be a calculated combination of the following, additional outcome measures:

  • Bilateral foveal fixation
  • Foveal binocularity
  • Fovea-tracked saccadic latency
Four individual scans through study completion: Day 0, Day 30, Day 60, Day 90.
Device Metrics
Time Frame: Four individual scans through study completion: Day 0, Day 30, Day 60, Day 90.
Bilateral foveal fixation will be measured as a percentage (from 0.00-1.00%) of time in which both eyes fixate together during the scan.
Four individual scans through study completion: Day 0, Day 30, Day 60, Day 90.
Foveal fixation
Time Frame: Four individual scans through study completion: Day 0, Day 30, Day 60, Day 90.
The device will capture each individual eye's ability to fixate as a percentage (from 0.00 to 1.00) of time during the scan. A result will be provided for each individual eye.
Four individual scans through study completion: Day 0, Day 30, Day 60, Day 90.
Device outputs
Time Frame: Four individual scans through study completion: Day 0, Day 30, Day 60, Day 90.
Fovea-tracked saccadic latency will be calculated in milliseconds to measure when fixation is attained and lost throughout the scan.
Four individual scans through study completion: Day 0, Day 30, Day 60, Day 90.
