3Treatment groups
Experimental Treatment
Active Control
Group I: Binocular cartoon treatment in officeExperimental Treatment1 Intervention
Participants will view a dichoptic binocular cartoon (provided by BBC) on the Nintendo 3DS-XL in office. They will continue to watch the cartoon for 60 minutes, 4 times a week, for 2 weeks. After 2 weeks, they will be given the option to continue for an additional 2 weeks (total of 4 weeks). Watching the cartoon does not require any special glasses. They will discontinue patching during this time.
Group II: Binocular cartoon treatment at homeExperimental Treatment1 Intervention
Participants will view a dichoptic binocular cartoon (provided by BBC) on the Nintendo 3DS-XL at home. They will continue to watch the cartoon for 60 minutes, 4 times a week, for 2 weeks. After 2 weeks, they will be given the option to continue for an additional 2 weeks (total of 4 weeks). Watching the cartoon does not require any special glasses. They will discontinue patching during this time.
Group III: Control groupActive Control1 Intervention
Participants will patch for 2 hours every day at home. After 2 weeks, they will be given the option to crossover to the teratment group for an additional 2 weeks (total of 4 weeks). Patching is a common treatment for amblyopia, often considered the "golden standard." It is the most common comparison as a "control" group in amblyopia and vision therapy literature.
