3D Movie Viewing vs Occlusion for Treating Amblyopia in Children
Starting soon · Not applicable
Conditions studied: Anisometropic Amblyopia, Strabismic Amblyopia
In brief
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.
