mTBI Identification and Monitoring Through Retinal Scanning

May 18, 2026 updated by: Rebiscan, Inc.

Mild Traumatic Brain Injury Identification and Monitoring Through Retional Scanning

Rebion has developed a device, the Rebion trauma tool (referred to as the head and intraocular trauma tool, or "HITT"), that detects ocular fixation and alignment using a binocular retinal scan. Preliminary data obtained from hospitalized patients with a clinically-confirmed traumatic brain injury (TBI) and uninjured controls indicates that the device can detect changes in ocular fixation, alignment, and saccades that are related to brain injury. This study seeks to evaluate the ability of the Rebion trauma tool to assess perturbations in eye movements resulting from TBI. The study will enroll 60 TBI patients and 20 controls.

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

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Controls
Participants should not be part of the Intended Use Population. Subjects that present to the hospital, clinic, or emergency department, either as a patient or non-patient, with no history of head trauma and, are 18-45 years of age.
Device: Head and Intraocular Trauma Tool
HITT device to scan the eyes of participants up to 3 times (~45 seconds each) at the time of admittance to study. The participant is to place the chin in the chin-rest and fixate on the illuminated light on the device.
Other Names:
  • HITT
TBI-Suspected Patients
TBI participants 18-45 years of age, recruited from patients at a clinical research facility who present with head trauma. Clinical evaluation for the patient can be positive (target condition present) or negative (target condition absent) for mTBI. Testing will occur on Day-0, Day-14, and Day-30.

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
TBI Detection
Time Frame: 1 day
Patients who present with suspected TBI to the clinic will have their eyes scanned to identify whether the HITT device can accurately identify patients with TBI.
1 day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
TBI Monitor
Time Frame: 14 days
Patients who present with suspected TBI to the clinic and had initially been tested for TBI detection will receive a second set of scans at 2 weeks to identify whether the HITT device can accurately identify patients with TBI.
14 days
TBI Monitor
Time Frame: 30 days
Patients who present with suspected TBI to the clinic and had initially been tested for TBI detection will receive a second set fo scans at one month to identify whether the HITT device can accurately identify patients with TBI.
