Binenbaum G, Tomlinson LA, de Alba Campomanes AG, et al. - Researchers conducted this prospective validation cohort study to assess the generalizability of the Postnatal Growth and Retinopathy of Prematurity (G-ROP) screening criteria in a new cohort of at-risk infants. This investigation was carried out at 41 hospitals in the United States and Canada from September 8, 2015, to June 13, 2017. The G-ROP criteria accurately predicted type 1 retinopathy of prematurity in 219 of 219 infants in a cohort study of 3,981 premature infants, while decreasing the number of infants receiving examinations by 35.6% if only infants meeting screening criteria received examinations. The revised screening criteria have been validated and could be clinically used to decrease the number of infants receiving examinations while consistently identifying retinopathy of prematurity that requires treatment.
