HITT for the Identification of Mild Traumatic Brain Injury

Study Overview
=================
Brief Summary
-----------------
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 100 TBI patients and 100 controls.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| TBI Patients<br>TBI participants 13 to 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. Enrollment is to occur within 2 weeks of the incident injury. | Device: Head and Intraocular Trauma Tool<br>* HITT device to scan eyes of participants up to 3 times ( 45 seconds each) at time of admittance to study. Participant is to place chin in chin-rest and fixate on illuminated light on device.<br>* Other names: HITT;Diagnostic Test: SCAT-5<br>* Participant is to complete Step 2 (Symptom Evaluation) and Step 3 (Cognitive Screening) of SCAT-5 test.<br>* Other names: Sport Concussion Assessment Tool - 5th Edition;|
| Controls<br>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. | Device: Head and Intraocular Trauma Tool<br>* HITT device to scan eyes of participants up to 3 times ( 45 seconds each) at time of admittance to study. Participant is to place chin in chin-rest and fixate on illuminated light on device.<br>* Other names: HITT;Diagnostic Test: SCAT-5<br>* Participant is to complete Step 2 (Symptom Evaluation) and Step 3 (Cognitive Screening) of SCAT-5 test.<br>* Other names: Sport Concussion Assessment Tool - 5th Edition;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| TBI Detection | Patients who have diagnosed TBI and are admitted to the hospital for treatment will have their eyes scanned to identify whether the HITT device can accurately identify patients with TBI. | 1 day | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| TBI Monitor | Patients who have remained in the hospital for TBI and received initial HITT device scan will receive a second set of scans at 2 weeks to identify whether the HITT device can accurately identify patients with TBI. | 14 days |
