Abstract

A retrospective analytic study was to determine the incidence and the significant risk factors of retinopathy of prematurity (ROP) in preterm infants at Chaoprayayomaraj Hospital during October 2005 and September 2008. The study enrolled the preterm infants with gestational age (GA) less than 37 weeks and birth weight less than 2,500 gm who received ophthalmologic eye ground examination at 4-6 weeks of chronological age. The incidence of ROP infants is 28.8 (128/427) percent. The study showed the significant risk factors by univariate analysis were the duration of oxygen therapy ≥ 31 days, gestational age (GA) less than 32 weeks and birth weight ≤ 1,000 gm. The duration of oxygen therapy ≥ 31 days and gestational age (GA) ≤ 32 weeks were found significantly odd ratio by multiple logistic regression analysis.
