Retinopathy of Prematurity Update on Classification, Screening, and Therapy

Retinopathy of prematurity (ROP) is a leading cause of preventable childhood blindness. This proliferative retinal vascular disease affects only prematurely born infants. Major risk factors include low gestational age and prolonged postnatal oxygen supplementation. ROP screening allows for timely identification of treatment-requiring infants and thus significantly reduces the risk of severe visual impairment and blindness from ROP. Current treatment options comprise retinal laser coagulation and intravitreal anti-vascular endothelial growth factor (VEGF) therapy. We provide a review of scientific data and current treatment recommendations, with special attention to the updated German guideline on ROP screening, the statement of the German ophthalmological societies on anti-VEGF therapy of ROP, and the new third edition of the International Classification of Retinopathy of Prematurity (ICROP3).
