Overview

Cross-sectional study estimates ROP prevalence in preterm infants, indicating severe risk factors.

Key Points

  • To estimate the prevalence of retinopathy of prematurity (ROP) in preterm infants and identify associated risk factors.
  • Retrospective observational cohort study
  • Analyzed medical records of infants with GA ≤ 32 weeks and/or birth weight ≤ 1,500 g between March 2022 and February 2024
  • Statistical analyses included Mann–Whitney U test, chi-square test, Fisher's exact test, and multivariable logistic regression with LASSO
  • Prevalence of ROP was 19.2% among 208 infants, with stage 2 being the most common (42.5%)
  • Treatment was needed for 25% of ROP cases
  • Extreme prematurity and female sex were identified as independent risk factors for ROP, while jaundice showed an inverse association
