Abstract:AIM: To investigate the relationship between the macular hemorrhage and refractive abnormalities,and analyze the occurrence probability and the factors of refractive abnormalities in high-risk neonates.
METHODS: From January 2017 to January 2018, a total of 1 229 neonates with high-risk factors invided into 3 groups, according to the different parts of retinal hemorrhage, examined by RetCamⅢ device. All the subjects were checked the refractive status by autorefractor when they were 1 to 1.5 years old. The abnormalities were checked their refractive status under using of 1% atropine oculentum after 7d. The relationship between the macular hemorrhage and refractive abnormalities, and the occurrence probability and the factors of refractive abnormalities were analyzed.
RESULTS: Among 205 eyes which were retinal hemorrhage irrelated macula 6 eyes had refractive abnormality(2.93%)in group A. 57 eyes which were macular hemorrhage 17 eyes had refractive abnormality(29.82%)in group B. 2 196 eyes which were no retinal hemorrhage 40 eyes had refractive abnormality(1.82%)in group C. It had significant difference between groups A and B, groups B and C(P<0.001), but had no significant difference between groups A and C(P=0.27). Multivariate Logistic regression analysis showed that macular hemorrhage and neonatal hypoxic ischemic encephalopathy were the independent risk factors for refractive status.
CONCLUSION: The incidence of refractive abnormality was high in macular hemorrhage. Macular hemorrhage and neonatal hypoxic ischemic encephalopathy were the independent risk factors for refractive abnormality,and we should strengthen the observation and intervention of such new-borns.
