Amblyopia is the leading cause of monocular visual impairment in children, affecting 3% population. Patching can improve visual acuity for 73% to 90% of children with amblyopia, but 15% to 50% may never achieve normal visual acuity after a lengthy course of treatment. Amblyopia recurs after successful treatment in 25% to 50% of children, and normal binocularity is rarely restored after patching treatment.Because amblyopia arises from binocular discordance when pediatric eye disorders (eg, strabismus or anisometropia) are present, binocular treatments are likely to yield better vision outcomes.
A binocular iPad game was effective in treating childhood amblyopia and was more efficacious than patching at the 2-week visit. Binocular games that re balance contrast to overcome suppression are a promising additional option for treating amblyopia. Fellow eye patching has long been the standard…
