Role of Cord Blood Cytokines and Perinatal Factors in Prediction of Retinopathy of Prematurity

Cord blood will be taken after birth for evaluation of cytokines level. At age of 4-6 weeks, we will do fundus examination for babies . Retrograde, we will study the perinatal risk factors in subjects found to have retinopathy. Follow up fundus will be done according to results of the first examination. By this study,we will be able later on to predict whom of preterm infants are more prone to develop retinopathy of prematurity.
