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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 study tested a custom, low-cost eye imaging device to see if it can produce retinal images as good as those from expensive commercial machines. Eleven healthy adults had their retinas scanned with both devices. The goal was to check if the cheaper device could clearly show the retina's structure, which could help make eye screening more affordable worldwide.

What this could mean

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

Active substance
low-cost optical coherence tomography device
What this could lead to
If successful, this could make retinal imaging more affordable and accessible, especially in low-resource settings.
What could go wrong
This is a very small, early-stage device comparison with only 11 participants. It does not test treatment or health outcomes, only image quality.

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

11 people

The number who actually took part.

Started

Mar 2024

Finished

May 2024

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 to 85 years

Sex

Anyone

Healthy volunteers

Accepted

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

Show the full entry requirements

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

Inclusion Criteria: * able to provide informed consent Exclusion Criteria: * potentially confounding ocular conditions, such as: glaucoma, current corneal injury, retinal damage, diabetes, corrected distance visual acuity worse than 20/40 * eyes that have had intraocular surgery, other than cataract surgery If two eyes satisfy the inclusion / exclusion criteria, both eyes will be included in the study. If only one eye satisfies the criteria, only the qualifying eye will be included in the study.
