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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is testing whether a special training program can help children with visual impairment learn better viewing strategies. The training involves six weeks of exercises that teach kids how to look in a structured way, zoom in and out, and tell objects apart. Researchers will measure changes in reading accuracy, reading speed, and visual search skills in 60 children aged 5 to 12.

What this could mean

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

Active substance
viewing strategy training
What this could lead to
If successful, this could provide an evidence-based training method to help children with visual impairment process visual information more efficiently.
What could go wrong
This is an early-stage study with only 60 participants, and it is not yet known if the training will lead to lasting improvements. Results may not apply to all children with visual impairment.

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 60 people

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

Started

Oct 2024

Expected to finish

Dec 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

5 to 12 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 typically developing children with normal vision: * Age 5-12 years * linear distant visual acuity of 0.1 logMAR or better * Verbal IQ above 70 * Absence of developmental disorders or psychiatric problems like ASS or AD(H)D Inclusion criteria for children with ocular visual impairment: * Age 5-12 years * Children with linear distance visual acuity better \<=1.3logMAR and \>0.1 logMAR * Intact central visual field (at least \> 30 degrees) * Children with a verbal IQ above 70 * Absence of developmental disorders or psychiatric problems like ASS or AD(H)D Inclusion criteria for children with cerebral visual impairment: * Age 5-12 years * Linear distance visual acuity \<=0.3 logMAR * Having the diagnosis CVI (verified by ophthalmologists) * Children with a verbal IQ above 70 * Absence of psychiatric problems like ASS or AD(H)D Additional inclusion criterion for study 2 (evaluating training effectiveness): children with (cerebral) visual impairment should have an indication for viewing strategy training. Training should not be indicated if children have no problems performing academic tasks (i.e. when speed and accuracy of visual processing is within the normal range). The age range for study 2 is 5-9 years. Exclusion criteria: * Children with VI: linear near visual acuity \>1.0 logMAR * Children with visual field defect \< 30 degrees * Children with a verbal IQ below 70 * Children who attended a form of vision training in the past two years * Children with psychiatric problems like ASS or AD(H)D * Auditory impairment or language impairments * Major life events during training
