Abstract: Objective To probe the classification of retinal hemorrhage(RH) in vaginal delivery term newborns according to digital wide-angle retinal imaging device(RetCam-3 ). Methods A total of 1 021 healthy full-term normal delivery newborns(2 042 eyes)were enrolled in this study.A digital wide-angle retinal imaging device(RetCam m) was used to examine the subjects at about 3 days after birth. Newborns with RH were reexamined after three, four and six weeks. RH was classified according to the location of RH and degree of hemorrhage in macular by RetCam-3. Results In 1 021 cases of newborns,retinal hemorrhages were found in 165 infants(17.14%).Within these 165 infants,155 infants(16.16%)wereⅠdegree retinal hemorrhage, 9 infants(0.88%) were Ⅱdegree retinal hemorrhage and 1 infant (0.01%) was Ⅲ degree retinal hemorrhage. The average time of second stage of labor in newborns without RH was 49.81±5.3 minites. The average time of second stage of labor in newborns with RH was 51.13±6.12 minutes. Newborns with RH had longer second stage of labor than those without RH. The difference was statistically significant (t=2.839, P=0.005). Conclusion According to the result of RetCam-3 of 2 042 eyes, we classify RH in degreeⅠ,Ⅱ and Ⅲ. RH of DegreeⅠis located in the superficial retina and resolves itself within three weeks after birth. RH of DegreeⅡ is located in the superficial retina including macular and resolves itself within six weeks after birth. RH of Degree Ⅲ is located ahead of retina including macular and does not resolve itself within six weeks after birth.Prolonged second stage of labor may play roles of risk factor in retinal hemorrhage.
