Objective. The purpose of this study was to explore the underlying clinical factors associated with the degree of retinal hemorrhage (RH) in full-term newborns. Methods. A total of 3054 full-term infants were included in this study. Eye examinations were performed with RetCamIII within one week of birth for all infants. Maternal, obstetric, and neonatal parameters were compared between newborns with RH and controls. The RH group was divided into three sections (I, II, and III) based on the degree of RH. Results. RH was observed in 1202 of 3054 infants (39.36%) in this study. The quantity and proportion of newborns in groups I, II, and III were 408 (13.36%), 610 (19.97%), and 184 (6.03%), respectively. Spontaneous vaginal delivery (SVD), prolonged duration of second stage of labor, advanced maternal age, and neonatal intracranial hemorrhage positively correlated with aggravation of the degree of RH in newborns. Conversely, cesarean section was protective against the incidence of RH. Conclusions. SVD, prolonged duration of second stage of labor, advanced maternal age, and neonatal intracranial hemorrhage were potential risk factors for aggravation of the degree of RH in full-term infants. Accordingly, infants with these risk factors may require greater attention with respect to RH development.
