Risk Factors of Retinopathy of Prematurity in Tertiary Hospital

Abstract

Introduction: Retinopathy of prematurity is a potentially blinding disease of the eye due to abnormal retinal vascularization. Gestational age, preterm birth, oxygen therapy, and RBC transfusion are some of the factors associated with ROP. Purpose: This study aims to determine the relation between gestational age, birth weight, duration of oxygen therapy, and RBC transfusion with ROP. Methods: This research is a case-control study using medical records data from Dr. Soetomo General Hospital in the period of January -June 2019. Data is analyzed using logistic regression analysis in SPSS v. 25. Results: The case group consists of 22 patients with ROP while the control group consists of 66 patients without ROP. Gestational age (p=0.030; OR=3.10, 95% CI 1.113-8.606) and duration of oxygen therapy (p=0.012; OR=3.75, 95% CI 1.342-10.481) shows a statistically significant relation with ROP. There is no relation between birth weight (p=0.098; OR= 2.30, 95% CI 0.857-6.171) and RBC transfusion (p=0.881; OR=1.09; 95% CI 0.343-3.480) with ROP. Conclusions: There is a relation between gestational age and duration of oxygen therapy with ROP. Meanwhile, birth weight and RBC transfusion have no relation with ROP.
