3D Movie Viewing vs Occlusion for Treating Amblyopia in Children
56 participantsStarted 2026-05-01
Plain-language summary
Amblyopia is a common childhood visual disorder that affects vision in one eye and can also impair depth perception (stereopsis). Standard treatment typically involves occlusion therapy (patching the stronger eye), which improves visual acuity but often does not fully restore binocular vision.
This study aims to evaluate whether watching 3D movies, combined with occlusion therapy, improves visual outcomes more than occlusion therapy alone in children with amblyopia. The immersive nature of 3D content may stimulate binocular vision and enhance treatment effectiveness.
In this randomized controlled trial, children aged 4 to 14 years with amblyopia will be assigned to one of two groups: one group will receive standard occlusion therapy, while the other will receive occlusion combined with weekly 3D movie sessions. After an initial phase, all participants will have access to 3D viewing sessions.
The study will assess improvements in depth perception, visual acuity, and eye alignment over time. The goal is to determine whether this combined approach provides additional benefits and could be used as a complementary therapy for amblyopia.

Inclusion Criteria:
Children aged 4 to 14 years Diagnosis of unilateral amblyopia (anisometropic, strabismic, or mixed) Interocular visual acuity difference ≥ 0.2 logMAR (equivalent to ≥ 2 Snellen lines) Ability to understand and follow age-appropriate instructions Written informed consent from parents or legal guardians Child assent obtained when applicable
Exclusion Criteria:
Previous treatment for amblyopia Ocular surgery within the last 6 months Strabismus with deviation greater than 10 prism diopters Presence of other ocular pathologies affecting vision (e.g., cataract, nystagmus, ptosis, corneal opacity, retinal disease, optic neuropathy) Neurological or cognitive impairment preventing compliance with study procedures Prior intensive exposure to 3D movies or virtual reality/3D video games that could act as a confounding factor Refusal of the child or family to participate
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
