Introduction : Retinopathy of prematurity (ROP) is a retinal proliferative vascular disorder of premature infants. In spite of improvement in the management of neonatal disorders, ROP is one of the leading causes of blindness in premature infants in the world. Present screening of ROP first is based on risk factors of birth weight and gestational age. Nevertheless, some authors believe that other risk factors, including maternal and perinatal factors and nutrition and genetics, are effective too. Nevertheless, we decided to study risk factors of ROP in neonates. Materials & Methods : This cross-sectional study on the population of neonates born in Ilam hospitals during 2012-2018. In this study we evaluated ROP in premature infants that were hospitalized in Ilam hospitals. Results : Altogether, 627 infants were evaluated, among them 332 boys and 295 girls. For the mean of birth weight between them, there was a significant difference (P-value=0.001). In addition, gestational age according to sex had a difference; in girls it was less than boys, and it was statistically significantly different (P-value=0.001). ROP was found to be significantly more prevalent in girls compared to boys. Prevalence of ROP among girls and boys was 27.8% and 15.7%, respectively. The prevalence of retinopathy in two sexes was 18.7%. Conclusion : Among these factors, birth weight, gestational age, blood transfusion history, PDA, and asphyxia had statistically significant differences with the occurrence of ROP. The best way to avoid the progression of ROP is screening and examination and timely treatment of this disorder.
