Keywords:Low birth weight, Prematurity in preterm infant, Retinopathy, Oxygen therapy
Background: Premature infants have avascular or incompletely vascularized retina at birth and ROP evolves over 4-5 weeks after birth. The aim of this study is to know the prevalence of retinopathy of prematurity in preterm infants, with birth weight ? 1500 grams and/or gestational age ?32 weeks in a tertiary care center.
Material and methods: The study was conducted in a tertiary care center of Bihar region India The sample size is 145 babies. All preterm infants admitted with a birth weight of ?1500 grams and/or ? 32 weeks of gestation and baby those at risk of ROP.
Results: 145 babies have enrolled during the study period of which 124 babies fulfilled the inclusion criteria and completed this prospective study.15 babies could not complete the follow-up protocol and 6 babies died before full vascularization of the retina. 124 babies who fulfilled the inclusion criteria were screened and 33 babies were found to have ROP. The prevalence of ROP in this study is 26.6%.
Conclusions: Among the preventable causes of blindness in children, ROP figures very high on the agenda. Low birth weight and gestational age were found to be the most important risk factors for the development of ROP.
