Amblyopia
Conditions
Brief summary
This project addresses the challenge of visual function intervention in children with monocular anisometropic amblyopia. It employs two innovatively designed digital games combined with occlusion therapy to conduct visual function training through parent-child interaction in home or multi-scenario environments. The study will compare this combined approach against traditional occlusion therapy alone, evaluating improvements in visual function, intrinsic motivation, and emotion regulation before and after the intervention. The research aims to promote the implementation and dissemination of personalized and engaging healthcare services. Ultimately, it seeks to establish a comprehensive visual function training product and service system suitable for daily use in home settings, with the goals of reducing medical anxiety in children and holistically enhancing treatment efficacy, training compliance, and overall clinical experience.
