A Comparative Study of the Efficacy of AR Based Amblyopia Training Therapy and Occlusion Therapy in Older Children and Adults With Amblyopia
China60 participantsStarted 2026-06-01
Plain-language summary
The goal of this clinical trial is to investigate the efficacy and safety of dichoptic treatment based on Augmented Reality (AR) technology in treating monocular amblyopia aged 12 to 55 years, and compare dichoptic AR treatment with the standard patching therapy. The main questions it aims to answer are:
Does dichoptic AR treatment safely and effectively improve visual acuity and other monocular/binocular visual functions in older children and adults with amblyopia? Is binocular therapy superior to occlusion therapy?

Inclusion criteria
. Individuals aged 12 to 55 years (12 ≤ age ≤ 55 years). Written informed consent shall be obtained from participants aged 18 years and above, or their legal guardians for those aged 12 to 17 years.
. Unilateral amblyopia with the following criteria: the best-corrected visual acuity (BCVA) of the dominant eye ≥ 0.8, and an interocular BCVA difference of two or more lines. Participants shall have confirmed amblyopia with relevant risk factors and no organic ocular diseases.
. For Individuals with refractive errors: the spherical equivalent (SE) measured via cycloplegic autorefraction or phoropter refraction ≤ -6.00 D. All participants shall have received optical refractive correction for more than 3 months, with stable visual acuity (acuity change \< 1 line) within the latest 2 months.
. Individuals with orthotropic eye position, including patients with strabismic amblyopia after strabismus correction. The distance manifest deviation measured at 6 m using the prism and alternate cover test shall be within 5 prism diopters (△).
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?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
