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 This study
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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compares three commonly used instruments for scleral depression, a routine eye exam technique that presses on the eye to view the retina. The goal is to see which tool causes the least pain and is easiest for doctors to use. Adults with symptoms of posterior vitreous detachment will have each eye examined with a different instrument and rate their discomfort.

What this could mean

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

Active substance
Three scleral indentation instruments: Schocket scleral depressor, Josephberg-Besser scleral depressor, and cotton tip applicator
What this could lead to
If one instrument proves more comfortable, it could become the preferred tool for routine retinal exams, reducing patient discomfort.
What could go wrong
The trial is small and measures subjective pain, which varies widely. Results may not apply to all patients or 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 75 people

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

Expected to start

Jul 2027

An estimate. Start dates often move.

Expected to finish

Jul 2028

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 to 100 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: * Symptomatic posterior vitreous detachment with or without vitreoretinal pathology Exclusion Criteria: * Monocular status. * Media opacity which precludes view of the peripheral retina. * Inadequate examination (cooperation with examination, inability to achieve all directions of gaze). * Underlying oculodynia (recent surgery, intraocular inflammation, abnormal intraocular pressure, ocular dysesthesia syndromes (ocular, adnexal or orbital). * History of pain-sensitizing conditions or current analgesic use. * Previous scleral indented examination poorly tolerated.
