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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at fluid and tissue samples from the eyes of people with glaucoma and cataracts, and compares them to samples from people with cataracts only. The goal is to find chemical and protein patterns that could help doctors diagnose or track glaucoma better in the future. About 40 adults scheduled for eye surgery will take part.

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 40 people

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

Started

Jan 2026

Expected to finish

Nov 2027

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.

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

Inclusion Criteria: * Age ≥ 18 years. * Scheduled for cataract surgery (phacoemulsification with intraocular lens implantation). * Ability to provide written informed consent. * For glaucoma arm: diagnosis of primary open-angle glaucoma (POAG) with coexisting cataract, and planned combined cataract surgery with glaucoma procedure. * For control arm: cataract without glaucoma and without other significant ocular pathology. Exclusion Criteria: * Age \< 18 years. * Pregnancy or breastfeeding. * Advanced visual impairment in the study eye (visual aquity worse than counting fingers). * Any glaucoma type other than primary open-angle glaucoma (e.g., angle-closure, secondary, neovascular glaucoma). * History of intraocular surgery in the study eye (including glaucoma surgery), vitreoretinal surgery, corneal transplantation, or refractive surgery. * Active or previous uveitis. * Other significant chronic ocular disease in the study eye (other than cataract and POAG in the glaucoma arm). * Inability to comply with study procedures or follow-up visits.
