摘　　要：目的洛阳市城乡结合部学龄前儿童屈光发育现状调查,应用Thibos矢量分析法分析该群体的散光参数,为学龄前儿童眼保健工作提供科学依据。方法回顾性调查设计;分层整群随机抽样法选取3~4岁小班组270例(540眼),4~5岁中班组360例(720眼),5~6岁大班组360例(720眼);将入组学龄前儿童的眼健康体检数据进行统计分析。结果我市城乡结合部学龄前儿童低常视力发生率为27.47%,组间差异具有统计学意义(P<0.001)。不同年龄组球镜、柱镜及等效球镜(M值)组间差异具有统计学意义(均P<0.05)。对三组散光参数进行傅利叶矢量转化后的规则散光(J_(0)成分)及不规则散光(J_(45)成分)组间差异无统计学意义(P均>0.05),而矢量长度(P成分)组间差异具有可比性(P<0.001);三组散光类型分布无明显统计学差异(P>0.05);在三组M值(等效球镜)及P成分参数组间多重对比中,3~4岁组与4~5岁组(P<0.001)、3~4岁组与5~6岁组(P<0.001)存在统计学差异;Spearman相关性分析发现三组M值参数与P成分参数均呈正相关性(均P<0.001)。结论我市城乡结合部学龄前儿童具有较高的视力低常及散光发生率,M值可作为评估学龄前儿童屈光发育状态的有效指标;应明确傅利叶矢量转换在分析屈光参数准确性中的优势。Objective Based on the investigation of the refractive development status of preschool children in the urban-rural fringe of Luoyang city,The Thibos vector analysis method was used to analyze the astigmatism parameters of the group and to provide a scientific basis for the eye care work of preschool children in the urban-rural fringe.Methods Retrospective survey design.According to the stratified cluster random sampling method,270 cases(540 eyes)were selected in primary class aged 3~4 years old,360 cases(720 eyes)were selected in middle class aged 4~5 years old,360 cases(720 eyes)were selected in top class aged 5~6 years old.The eye health examination data of preschool children were analyzed.Results The incidence of low normal vision of preschool children in the urban and rural fringe was 27.47%,and the difference between the groups was statistical significant(P<0.001).The sphere,column,and equivalent sphere(M value)differences were significant(all P<0.05).The regular astigmatism(J_(O) component)and irregular astigmatism(J_(45) component)differences of the three groups of astigmatism parameters were not statistically significant(all P>0.05),while the vector length(P component)differences were comparable(P<0.001);There was no statistical difference in astigmatism type distribution(P>0.05).In the multiple comparisons between the three groups for the M values and P component parameters,there were statistical differences between 3~4 and 4~5 years old(P<0.001),3~4 and5~6 years old(P<0.001).Spearman correlation analysis found a positive correlation between M value and P component parameters in the three groups(all P<0.001).Conclusion Preschool children in the urban and rural fringe areas of our city have a high incidence of low vision and astigmatism,the M value can be used as an effective indicator to evaluate the refractive development status of preschool children.The advantages of Thibos vector analysis method in analyzing the accuracy of astigmatism parameters should be clarified.
