3D Movie Viewing vs Occlusion for Treating Amblyopia in Children
Sponsor: Universitat Politècnica de Catalunya
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.

Interventions
3D Movie Viewing
Participants will watch 3D movies using active shutter glasses in a controlled environment. Sessions will be conducted once weekly, each lasting approximately 90-120 minutes, over a total of 3 to 6 sessions. This intervention aims to stimulate binocular vision through exposure to large binocular disparities in an immersive and engaging setting.
Occlusion Therapy
Standard occlusion therapy of the non-amblyopic eye prescribed according to clinical guidelines and amblyopia severity. Treatment is performed at home for a specified number of hours per day, depending on clinical indication, with the goal of improving visual acuity in the amblyopic eye.
