International Classification of Retinopathy of Prematurity, 3rd Edition (ICROP3)

ICROP is a consensus statement that creates a standard nomenclature for ROP care. It was initially published in 1984, revisited in 2005, and now revised in 2021. This third edition is required because of advances in pediatric retinal imaging that are creating concerns about subjectivity in diagnosis, and new disease therapies (eg, anti-VEGF agents) that are creating challenges related to post-treatment regression and reactivation. Every pediatric ophthalmologist should become familiar with ICROP3 because it affects routine ROP care.
