Amblyopia is a condition in which the best-corrected visual acuity is less than the age-appropriate visual a-cuity or is two or more lines worse than the fellow eye,due to form deprivation and/or abnormal binocular interaction dur-ing visual immaturity.In 2022,the American Academy of Ophthalmology updated the treatment recommendations in the Preferred Practice Pattern(PPP).In 2021,the Chinese Association for Pediatric Ophthalmology and Strabismus published the Expert Consensus on Prevention and Treatment of Amblyopia in Children(2021).This article compares and analyzes the PPP 2022,the Amblyopia Preferred Practice Pattern 2017 and the Chinese Expert Consensus 2021,focusing on the up-dates of the new version of the PPP in terms of treatment,as well as the differences between China and foreign countries in treatment modalities and follow-up assessment,with a view to share with Chinese ophthalmic colleagues about the latest treatment of amblyopia.
