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 Results may not be published yet.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.

Summary

Researchers are testing a home computer game that uses special glasses to train the weaker eye in children with lazy eye (amblyopia). The game shows patterns called Gabor patches to the lazy eye while the stronger eye sees a noise mask. The trial compares this game with standard patching therapy in children aged 4 to 12, and also tests whether combining the game with patching helps when patching alone fails. The main goal is to see if the game can improve visual acuity as well as or better than patching.

What this could mean

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

Active substance
a home-based computer game using dichoptic Gabor patches and anaglyph glasses
What this could lead to
If it works, children with lazy eye could have a home-based alternative to patching that is easier to stick with.
What could go wrong
The game may not improve vision as much as patching, and some children may find it hard to use consistently. This is a mid-stage trial, so results may not apply to all children with lazy eye.

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

Inclusion Criteria: * The sample will be made up of children with amblyopia from 4 to 12 years old (amblyopia will be defined as the best corrected visual acuity less o equal to 0.8 in decimal units or \> 2 lines of difference between both eyes). Strabismus inclusion criteria will be \< 25 prismatic diopters, with a deviation ≥ 2 prismatic diopters. Exclusion Criteria: * Subjects with nystagmus, ocular pathology o cognitive delay will be excluded.
