Aim to quantify the risk of treatment for retinopathy of prematurity (ROP) among infants meeting current U.S. screening guidelines. Among infants ≤1500 g birth weight or ≤30 weeks gestation screened for ROP from 2006-2015, we developed a risk prediction model to identify infants treated for ROP. Applied to 6,127 infants discharged in 2016, our model had 97.9% sensitivity, 63.3% specificity, positive predictive value of 4.0%, and negative predictive value of 99.9%. Large numbers of infants at low risk of developing ROP are required to undergo screening. Refining current ROP guidelines may reduce unnecessary examinations.

This study aimed to determine the association between hyperglycemia, insulin therapy, and severe retinopathy of prematurity (ROP) in extremely low-birth-weight (ELBW) infants. Hyperglycemia alone was not associated with severe ROP in ELBW infants. However, researchers did observe a possible trend between the use of insulin and severe ROP.

We identified premature infants who were discharged from Pediatrix Medical Group neonatal intensive care units from 2003–2012 and who received an ophthalmologic exam. We matched each infant exposed to sildenafil prior to first eye exam to three non-exposed infants using propensity scoring to control for differences in baseline infant characteristics. We evaluated the association between sildenafil exposure and development of severe ROP using conditional logistic regression.
