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 Results may not be published yet.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 tested a minimally invasive surgery called GATT in 30 children who developed glaucoma after cataract surgery. The procedure aims to lower eye pressure by improving fluid drainage inside the eye. Researchers measured changes in eye pressure and the number of glaucoma medications needed over 12 months.

What this could mean

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

Active substance
gonioscopy-assisted transluminal trabeculotomy (GATT) procedure
What this could lead to
If successful, this procedure could offer a safer, less invasive way to control eye pressure in children with glaucoma after cataract surgery, reducing the need for medications.
What could go wrong
This is a small, single-center study with only 30 participants and no comparison group. Results may not apply to all children, and long-term safety beyond 12 months is unknown.
