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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether adding osteopathic manual therapy (a type of hands-on body treatment) to standard vision therapy can help people with eye coordination problems that cause eyestrain, blurred vision, and headaches. The trial will involve 100 adults who work on screens and have symptoms of binocular vision dysfunction. Participants will be split into three groups: vision therapy alone, vision therapy plus real osteopathy, or vision therapy plus a sham (fake) osteopathy treatment, and researchers will measure changes in eye movement and symptom scores.

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 100 people

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

Expected to start

Apr 2026

An estimate. Start dates often move.

Expected to finish

Feb 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.

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: * Adult workers (≥18 years) whose regular occupational duties involve screen-based work. * Presence of symptoms consistent with binocular vision dysfunction, defined as a Convergence Insufficiency Symptom Survey (CISS-V15) score ≥21 at baseline screening. Exclusion Criteria: * Severe ocular disease or systemic conditions affecting vision (e.g., age-related macular degeneration, retinopathies, glaucoma, keratoconus). * Neurological disorders affecting ocular motility or visual function (e.g., multiple sclerosis; cranial nerve III, IV, V, or VI palsy). * Manifest ocular deviation not suitable for management with visual therapy. * Inadequate refractive correction or prism requirement \>10 prism diopters (\>10Δ). * Refractive surgery (LASIK/PRK), cataract surgery, or any ocular surgery likely to influence binocular vision within the past 6 months. * Use of medications known to affect ocular motility or accommodative function. * Cognitive impairment or neurological conditions interfering with adherence to therapy instructions. * Suppression or severe amblyopia limiting response to visual therapy. * Best-corrected visual acuity \<0.5 decimal (equivalent to worse than 20/40) at distance or near.
