What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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

Summary

This study tests whether an extra 8-minute MRI scan can better detect anterior ischemic optic neuropathy (AION), a type of eye stroke. Researchers will enroll 250 adults with suspected AION and compare the new scan to standard MRI. The goal is to see if the new method is more sensitive at finding nerve damage in the eye.

What this could mean

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

Active substance
MRI scan with an added diffusion sequence
What this could lead to
If successful, this could provide a faster, more accurate way to diagnose eye stroke, helping doctors start treatment sooner.
What could go wrong
This is an early diagnostic study, not a treatment trial. The new MRI sequence may not prove more accurate than standard scans, and results may not apply to all patients.
