An interventional study of Autostereoscopic 3D Training and Conventional Patching in Amblyopia, Visual Training and Visual Functions, sponsored by Beijing Tongren Hospital. Not yet recruiting at 1 site in China. Open to participants aged 7 Years to 12 Years. Per ClinicalTrials.gov, last updated 2026-07-17.
Sponsored by Beijing Tongren Hospital · Not applicable, Interventional, and Treatment
The goal of this clinical trial is to learn if an autostereoscopic 3D amblyopia training system works to improve vision in children and adolescents with amblyopia. It will also learn about the safety and tolerability of the 3D training system. The main questions it aims to answer are:
Participants will:
189 studies on the registry are indexed under Amblyopia; 41 are open to participants now.
This study's planned enrollment of 34 is below the median of 60 across 137 interventional studies indexed under Amblyopia.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Device: Autostereoscopic 3D Training
Device: Conventional Patching
Daily 20-minute autostereoscopic 3D amblyopia training session, 5+ days per week for 6 months. Training consists of 15 minutes of monocular perceptual learning with Gabor patches (adaptive difficulty algorithm) and 5 minutes of binocular vergence training. Home-based training with remote data monitoring.
Daily continuous 2-hour occlusion of the non-amblyopic eye using medical adhesive eye patches, 5+ days per week for 6 months. Patients are encouraged to perform near visual activities (reading, writing, puzzles) during patching to enhance amblyopic eye stimulation. Parent-supervised home therapy with daily patching logs.

Start is estimated for Jul 2026; primary completion for May 2027, 10 months later.
Of 58 non-industry interventional studies with no phase under Amblyopia, half reached primary completion within 34 months of starting (the median), counting those still running; a quarter within 21 and three quarters within 72. This study's planned 10 months is below that.
Counting every sponsor, half of 71 studies reached it within 33 months; a quarter within 17 and three quarters within 47.
