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 This study
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 Results may not be published yet.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.

Summary

This study tests a device that uses real-time sound feedback to help people with vision loss fix their gaze on a target. Participants hear sounds that guide their eyes back to center when they drift. The goal is to improve the quality of eye imaging by reducing blur from eye movements. The trial includes 22 healthy volunteers and patients with retinal diseases or blindness.

What this could mean

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

Active substance
acoustic real-time biofeedback device (eyeFAST)
What this could lead to
If it works, this could help patients with vision loss hold their gaze steady, making eye scans faster and more accurate.
What could go wrong
This is a very small, early proof-of-concept study with only 22 participants. The device may not improve fixation in real-world clinical settings.

Study facts

What this study's own registry entry says, in plain language.

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 22 people

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

Started

Aug 2025

Expected to finish

May 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.
