About

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.

Enrollment: 60 estimated patients

Trial design

60 participants in 2 patient groups

Controls

Description:

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.

Treatment:

Device: Head and Intraocular Trauma Tool

TBI-Suspected Patients

Description:

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.

Treatment:

Device: Head and Intraocular Trauma Tool
