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 This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial compares a new autostereoscopic 3D vision training system to standard eye patching for children aged 7 to 12 with amblyopia (lazy eye). Participants use the 3D system for 20 minutes daily or wear an eye patch for 2 hours daily over 6 months. The study measures improvements in vision and any side effects to see if the 3D approach is a better treatment option.

What this could mean

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

Active substance
autostereoscopic 3D vision therapy system
What this could lead to
If it works, this could offer a more engaging and effective alternative to eye patching for treating amblyopia in children.
What could go wrong
This is a small early-stage trial, so results may not apply broadly. The 3D training could cause discomfort or side effects like eye strain.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 34 people

The number the study aims to enrol. It can still change while the study runs.
