Head and Intraocular Trauma Tool for the Identification of Mild Traumatic Brain Injury

Active, not recruiting

• Conditions: Brain Injuries, Traumatic

• Registration Number: NCT05092295
• Lead Sponsor: Rebiscan, Inc.

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.

Study & Design

• Study Type: OBSERVATIONAL
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
TBI Detection	1 day	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.

Secondary Outcome Measures

Name	Time	Method
TBI Monitor	14 days	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.
