Validation and Feasibility of the Postnatal Growth and Retinopathy of Prematurity Retinal Screening Criteria at a Level IV Tertiary Care Neonatal Intensive Care Unit.

Objective: Retinopathy of prematurity (ROP) is detected in preterm infants by standardized screening programs, but in general, they have poor sensitivity. The Postnatal Growth and Retinopathy of Prematurity (G-ROP) algorithm uses weight gain to predict ROP superior reported sensitivity. Our objectives are to (1) independently validate the sensitivity of G-ROP criteria for the detection of ROP in infants born at >28 weeks' gestation in a tertiary care unit in the United States and (2) to calculate the cost savings associated with a potential reduction in examinations.
