Prevalence and predisposing factros of retinopathy of prematurity in very low-birth-weight infants discharged from NICU

ABSTRACT

Retinopathy of prematurity [ROP] is a disease of the eye caused by disorganized growth of retinal blood vessels resulting in scarring and retinal detachment. All preterm babies are at high risk for ROP, and very low birth weight is an additional risk factor. An increased incidence of ROP is expected in Iran because of improved survival of low birth weight and premature babies, and it is obvious that pediatricians and ophthalmologists are concerned about prevention and timely treatment of ROP in these children. To asses the real situation of ROP in our NICU we studied its prevalence and risk factors. This was a retrospective analysis of premature infants with birth weight of gestational age of Neonatal Intensive Care Unit of Qaem Hospital, Mashhad, Iran. The collected data of 47 cases in this cross-sectional study are analyzed by SPSS [Mann-Whitney, t-Student]. Forty five infants were included in the study. Out of these, 4 [8.5%] developed ROP [inclusive all stages]. Our analysis revealed that low gestational age, sepsis and respiratory distress syndrome were independent predictors for the development of ROP. The frequency of ROP in our hospital was lower than the range reported in developed countries, and our risk factors were a little different
