The aim of this study was to investigate the risk factors for Retinopathy of Prematurity (ROP) development and the potential effect of human breast milk among these factors. For this purpose, infants admitted to a tertiary referral clinic for ROP screening and treatment between April 2013 and May 2015, were included in this retrospective study. The demographic data, accompanying diseases, previous surgery, type of feeding and duration of human breast milk intake were recorded. According to the ROP screening examination results, infants were divided into two groups as those with ROP (infants at any stage of ROP) and those without ROP. Relationship between the risk factors and ROP were evaluated. The comparison of 221 infants without ROP and 99 infants with ROP; revealed that gestational age at birth, birth weight, mechanical ventilation support, bronchopulmonary and cardiac diseases, hydrocephaly, any previous surgery, infections, steroid treatment percentages were high and human breast milk intake percentage was low among infants with ROP. Mean breast feeding time for infants with ROP (3.81 ± 2.33 month) was shorter than the infants without ROP (5.51 ± 1.43 month) (p < 0.001). In logistic regression analysis, the duration of breast feeding was inversely related with ROP (OR 0.744; 95% CI 0.621-0.891; p < 0,001). These results suggest that gestational age at birth and accompanying diseases are the main risk factors for the development of ROP. As the duration of the breast feeding of the infants without ROP was longer than the infants with ROP; breast feeding may have a preventive effect on ROP development.
