@#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. <p>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.<p>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(<i>P</i><0.001), but had no significant difference between groups A and C(<i>P</i>=0.27). Multivariate Logistic regression analysis showed that macular hemorrhage and neonatal hypoxic ischemic encephalopathy were the independent risk factors for refractive status.<p>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.

@#AIM:To investigate the situation of amblyopia in preschool children, and to provide evidence for the protection of visual acuity and prevention of amblyopia in children. <p>METHODS: From 2010 to 2015, a total of 236 203 school aged children in our hospital in Chengdu were examined with routine visual acuity. This study was performed by the professional eye doctor in our hospital using the international standard visual acuity chart and statistically analyzed.<p>RESULTS: There were 18.85%(44 516/236 203)of the subjects in the children with refractive errors, and the rate of amblyopia was 6.12%(14 453/236 203). In anisometropic amblyopia type the rate was 68.19%(9 856/14 453), significantly higher than the proportion of other types, and the difference was statistically significant(<i>P</i><0.05). The composition ratio of mild amblyopia and medium amblyopiawas 53.69%(7 760/14 453)and 41.38%(5 980/14 453), which were significantly higher than that of severe amblyopia constitute 4.93%(713/14 453). Central monitor amblyopia proportion, 80.09%(11 575/14 453), was significantly higher than that of non center, and walk the proportion of amblyopia. The subjects were grouped according to their age. Amblyopia children who was <5 years old was 5.48%(6 254/114 213), higher than 5.33%(6 499/121 990)in ≥5 years old amblyopia children, but the difference was not statistically significant(<i>P</i>>0.05). <p>CONCLUSION: School-age children with anisometropic amblyopia type constructed the main body of amblyopia children in our city. Mild to moderate amblyopia and the central vision amblyopia were large proportion of children with amblyopia. We should strengthen the visual inspection of school-age children in our city and do the work of prevention and early treatment of amblyopia.
