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 Results may not be published yet.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
The full record has not been published yet, so there is little to show here.

This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a type of eye training called biofeedback can improve vision and quality of life in people with glaucoma. Glaucoma damages the optic nerve and can cause blind spots. The training teaches patients to move their eyes to use healthier parts of their retina. Seventy participants will be randomly assigned to receive the training or not, and their vision and daily function will be measured over time.

What this could mean

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

Active substance
visual biofeedback training
What this could lead to
If it works, this could offer a non-invasive way to help people with glaucoma make better use of their remaining vision and improve daily life.
What could go wrong
This is a small, early-stage trial with only 70 people. Biofeedback training may not lead to meaningful vision improvements, and results may not apply to all glaucoma patients.

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 70 people

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

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * 18-95 years old. * Glaucoma cases with adequate intraocular pressure control. * Presence of paracentral scotomata within two degrees of fixation. * Ability to follow instructions for biofeedback training. Exclusion Criteria: * Prior or current low vision rehabilitation treatment. * Ocular diseases or severe clinical conditions unrelated to glaucoma * Media opacities that prevent reliable microperimetry testing in both eyes. * Inability to perform study assessments or follow instructions for biofeedback training.
