To evaluate if broadening the criteria for retinopathy of prematurity (ROP) screening to include babies with gestational age ≥32 weeks and/or birth weight ≥1500 g, would have an impact on the number of babies diagnosed as having ROP.

A prospective cohort study was carried out at the Aga Khan University Hospital, Karachi, Pakistan. Infants with gestational age ≤35 weeks or birth weight ≤2000 g born in this hospital from May 2010 to December 2012 were screened for the presence of ROP 4–6 weeks after birth. Subsequent examinations were performed at intervals based on the findings of initial eye examinations. Infants diagnosed as having ROP were treated with argon laser therapy. Neonatal risk factors were also assessed. Cumulative incidence of ROP was calculated for babies falling within and outside current screening criteria. Multivariate logistic regression analysis was performed …
