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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a six-week program of eye exercises delivered through virtual reality can help adults aged 18 to 42 who have vision problems after a concussion. Participants are randomly assigned to either the eye exercise program or usual care (education and symptom management). The main goal is to see if a larger trial is possible, looking at recruitment, completion, and safety.

What this could mean

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

Active substance
Oculomotor exercises delivered in virtual reality
What this could lead to
If this approach works, it could point toward a new treatment for vision problems after concussion, helping people return to work and daily life more quickly.
What could go wrong
This is a small feasibility study, not designed to prove effectiveness. The exercises may not help everyone, and some people might find them uncomfortable or difficult to complete.
