Introduction: In the near future, retinopathy of prematurity (ROP) will be the most significant cause of blindness in upper and middle-income countries. Due to the increasing survival chances for premature and low birth weight infants and the importance of the diagnosis and treatment of ROP, this study was aimed at determining the prevalence of ROP and its related factors in Sanandaj, Iran, in 2014.

Methods: This cross-sectional study was performed on 47 preterm infants, weighing less than 2000 g or with a gestational age of less than of 34 weeks. The sampling method was census. From the first examination to 1 to 4 weeks later, until retinal vascularization completion, examinations were performed by the same ophthalmologist. Data were analyzed using SPSS version 20 and frequency, mean, SD and Chi-square tests.

Results: The prevalence of ROP in the infants was 10.6%. Prevalence among girls was 16% and among boys it was 4.5%. The results showed that 23.5% of infants with ROP needed mechanical ventilation. The difference between the two groups was statistically significant (p = 0.031).

Conclusion: In this study, the prevalence of ROP in the NICU and neonatal ward of Besat Hospital in Sanandaj was low. However, due to serious consequences of the disease in premature infants, timely screening, determination, and control of risk factors provided necessary support to manage the disease.
