International Classification of Retinopathy of Prematurity (2021) Michael F. Chiang, MD

Description

A consensus statement creating a standard nomenclature for the classification of retinopathy of prematurity (ROP). This Third Edition (ICROP3) addresses challenges posed by subjectivity, ophthalmic imaging innovations, novel anti-VEGF therapies, and varied ROP patterns globally. It retains current definitions of zone, stage, and extent, while introducing refinements like posterior zone II, notch, subcategorization of stage 5, and defining the continuous spectrum of vascular abnormality.
