Study Of The Retinopathy Of Prematurity Based On Gestational Age And Birth Body Weight

Abstract

The clinic can also indicate the incidence of ROP at the Tabriz University of Medical Sciences. The aim of this study was to evaluate the retinopathy of preterm infants based on birth weight and gestational age. Materials and Methods: After determining the frequency of neonatal retinopathy according to the rate of referral to the ROP clinic of Nikokari hospital during 2016, the neonates were divided into groups of 500 to 1000, 1001 to 1500, 1501 to 2000 and above 2000 grams and the frequency of ROP in each weight group was compared. Neonates were also divided into the following under 28 weeks, 29 to 30 weeks, 31 to 32 weeks, 33 to 34 weeks and over 34 weeks and the frequency of ROP in each age group was compared. Results: 661 patients were studied. 379 cases (57.3%) were male and 282 cases (42.7%) were female. 93 cases (14.1%) had ROP. The mean±SD of patients birth weight of patients with ROP was 1199.51±406.80 gr and was significantly lower than patients without ROP who had mean birth weight of 2022.69±649.73 gr (p=0.001). The mean±SD of gestational age of patients with ROP was 29.22±2.67 weeks and was significantly lower than non-ROP patients who had mean gestational age of 33.41±2.73 weeks (p=0.001).
