OBJECTIVE: Retinopathy of prematurity (ROP) remains one of the leading causes of childhood blindness. The current screening criteria in Canada have extremely high sensitivity but low specificity, leading to unnecessary examinations of neonates. Moreover, a screening algorithm that reduces the burden of screening is urgently needed owing to the increase in neonatal survival after extreme premature delivery, combined with the limited number of physicians qualified to screen for ROP. This retrospective study aimed to validate and compare the accuracy of the postnatal growth and ROP (G-ROP) and Weight, Insulin-like growth factor-1, Neonatal Retinopathy of Prematurity (WINROP) models for identifying neonates at risk for developing treatment-requiring ROP in a Canadian cohort.
DESIGN: Single-center retrospective cohort study conducted in Calgary, Alberta, Canada. Data from preterm infants born between 23- and 31-week gestational age or birth weight less than or equal to 1 250 grams were analyzed. A total of 1 001 infants were included in the study. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value for WINROP, and G-ROP algorithms were assessed in identifying neonates at risk of treatment-requiring ROP.
RESULTS: The WINROP algorithm yielded 95.7% sensitivity in identifying infants requiring ROP treatment compared to 100% sensitivity with the G-ROP model. Specificity for treatment-requiring ROP for WINROP was 41.7% and G-ROP was 30.4%.
CONCLUSIONS: The G-ROP model was found to be more appropriate in our cohort, lending itself seamlessly to clinical care, while providing 100% sensitivity and greater specificity compared to current screening guidelines in our cohort.
