Screening of infants' retina by RetcamⅢ / 中国医师杂志

ABSTRACT

Objective To investigate incidence and severity of retinopathy of prematurity (ROP)screened by RetcamⅢ and the related factors.Comparative case series were designed.Methods A study was performed among infants who required screening by RetcamⅢ in the second Affiliated Hospital & Yuying Children's Hospital of Wenzhou Medical University,and carried out between May 2012 and April 2013.A total of 1097 infants met the study criteria,and were divided into group Ⅰ (n =333 from outpatient screening) and group Ⅱ (n =764 from inpatient screening).Variables were recorded,including birth weight (BW),gestational age (GA),number of births (NOB,singleton/twins/triplets),gender,neonatal respiratory distress syndrome (NRDS),patent ductus arteriosus (PDA),neonatal asphyxia,neonatal hyperbilirubinemia,intracranial hemorrhage,congenital heart disease,neonatal anemia,neonatal sepsis,necrotizing enterocolitis (NEC),and bronchopulmonary dysplasia (BPD).The results of ophthalmological examinations by RetcamⅢ were also recorded.Spearman correlation analysis was used to identify the variables most significantly associated with ROP.Results There were 98 infants of ROP in group Ⅱ (total 764,12.8％).There was a significant association of ROP with variables (P ＜0.05),including BW,GA,and NOB.There was a significant association of ROP with diseases (P ＜ 0.05),including NRDS,neonatal asphyxia,intracranial hemorrhage,neonatal anemia,neonatal sepsis,NEC,and BPD.However,there was no association of ROP with diseases (P ＞ 0.05),including PDA,neonatal hyperbilirubinemia,and congenital heart disease.Conclusions RetcamⅢ can be used to screen retina of infants.ROP is still the most common eye disease in preterm infants.The incidence of ROP was 12.83％ in Wenzhou.Variables,including BW,GA,NOB,NRDS,neonatal asphyxia,intracranial hemorrhage,neonatal anemia,neonatal sepsis,NEC,and BPD,were the most significant factors associated with ROP.
