Study of retinopathy of prematurity in high risk infants

Abstract

Background: Retinopathy of prematurity is a vaso-proliferative disorder of retina in premature babies. The objective of this study was to study retinopathy of prematurity in premature babies and to study associated risk factors.Methods: Study was a prospective study was conducted among infants in high risk follow up clinic of our department KT Children Hospital, tertiary teaching hospital attached to Government medical college, Rajkot. Sample size of study was conducted on 100 high risk neonates who were brought to high risk follow up clinic at K T children hospital, Rajkot.Results: Out of studied 100 infant, 40% developed ROP, 12% developed stage 1 ROP, 13% developed stage 2 ROP,15% developed stage 3 ROP. Out of 100 cases 40% were ROP positive.15% occurred between 28-30 weeks of gestation. In 31-33 weeks of gestation 82.5%. In 34-36 weeks of gestation 2.5%. 15% of cases between 740-1000 gm of birth weight developed ROP.67.5% between 1000-1500 gm of birth weight developed ROP.15% between 1500-2000 gm of birth weight developed ROP.2.5% between 1500-2000 gm of birth weight developed ROP. 70 newborns received oxygen, 95% of newborns developed ROP. 5% newborns who have not received oxygen developed ROP. In present study there is association of ROP with oxygen therapy. 40 cases had apnea. Out of 40 cases 55% had ROP. Association between apnea and ROP. 21 received blood products.57% of them had ROP. Association between blood transfusion and ROP. 20 received ventilation. 75% of them had ROP. Association between ventilation and ROP. Out of 40 positive newborns there 17 were male and 23 were female. No difference in distribution of ROP in male and female sex. Significant relationship between gestational age, O2 therapy, mechanical ventilation, apnea and blood products. Insignificant relationship between sexes.Conclusions: This study has identified ROP is found to be associated with gestational age, o2 therapy, mechanical ventilation, apnea and blood products.
