Integrated Eye Tracking and Neural Monitoring for TBI: Optimization
An observational study of Traumatic Brain Injury, run by United States Naval Medical Center, San Diego at 1 site in United States.
Trial summary
Traumatic brain injury (TBI) is one of the most frequent injuries affecting service members. Unfortunately, current neurocognitive assessment tools are unable to reliably detect mild TBI more than a few days post- injury. Read more about this study

About this study
Official title: Integrated Eye Tracking and Neural Monitoring for Enhanced Assessment of Mild TBI: Clinical Optimization Study
Traumatic brain injury (TBI) is one of the most frequent injuries affecting service members. Unfortunately, current neurocognitive assessment tools are unable to reliably detect mild TBI more than a few days post- injury. Therefore, development of advanced systems for assessment and diagnosis of TBI are a top priority within Department of Defense. This project aims to evaluate a combined electroencephalography (EEG) and eye tracking system capable of assessing compromised cognitive function stemming from TBI, with the goal of enhancing operational readiness and aiding in diagnosis, improving health care and rehabilitation for affected military personnel.
Read the detailed description
This study (N=100) will be a correlational study to assess cognitive function in healthy controls, individuals with mild TBI, and individuals with moderate-to-severe TBI.
In general, participants will provide demographic information, medical history, and details of their head injury. Participants will also complete a brief neuropsychological assessment to obtain an index of cognitive ability, along with the Fusion Test with eye tracking and linked EEG. MRI data may also be obtained.

What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Mild TBI Group | History of head injury, Active Duty Service Member or Veteran, age 18-55, fluent in English | |

What is being measured
The primary outcome is the main question the study is designed to answer.
EEG
Spectral features and event related responses collected from scalp measurements during performance of an eye movement and working memory task.
Measured: One study visit
Eye Tracking
Saccadic latencies measured in response to cognitive task including working memory demands.
Measured: One study visit
Secondary outcomes (4)
Neurobehavioral Symptom Inventory (NSI)
Self-report measure of post-concussive symptoms

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
EEG (time frame: One study visit). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Feb 2022; AzTrials last refreshed its copy on 6 Nov 2026.
