What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study tests a device called HITT that scans the eyes to look for changes in eye movement that may occur after a mild traumatic brain injury (TBI). Participants who have had head trauma within the past two weeks will have their eyes scanned briefly, and their results will be compared to those without brain injury. The goal is to see if the device can accurately identify TBI, which could lead to faster and easier diagnosis in the future.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Head and Intraocular Trauma Tool (HITT) - a device that scans the eyes to detect changes in eye movement linked to brain injury
What this could lead to
If successful, this could lead to a fast, non-invasive way to detect mild traumatic brain injury, potentially aiding in quicker diagnosis and treatment.
What could go wrong
This is an early-stage study with a small number of participants, so the device may not prove accurate enough for wider use. Eye scans may not reliably distinguish TBI from other conditions.
