Binocular Visual Therapy and Video Games for Amblyopia Treatment in Children Aged 4 to 10 Years

What this Trial Is About

Amblyopia, also known as lazy eye, is a condition where one or both eyes have reduced vision that cannot be explained by an eye abnormality alone. It causes problems with contrast perception, movement detection, visual sharpness, focusing, and depth perception. Traditionally, treatment involves patching the stronger eye for two hours daily, but this can have compliance issues and vision often regresses after stopping treatment. Recent research suggests amblyopia may involve both eyes due to changes in brain visual pathways, leading to new binocular treatments that aim to improve vision in the lazy eye and restore depth perception. This study compares three treatment methods in children with amblyopia aged 4 to 10 years: Group A uses an eye patch on the stronger eye with near-vision activities like reading and drawing; Group B uses an eye patch on the stronger eye combined with an electronic tablet; Group C uses red-green glasses with an electronic tablet. Each group receives their assigned treatment for two hours every day over four months, followed by a two-month break to assess if vision problems return. Participants will have their vision and depth perception tested at the start, monthly during treatment, and two months after stopping treatment to check for relapse. The study will measure the best corrected visual acuity in the lazy eye and stereopsis at these times. The trial is double-blind and randomized, aiming to find which treatment helps improve vision and binocular function the most. The total involvement lasts about six months, including treatment and follow-up evaluations.
