摘　　要：目的探讨5~14岁儿童屈光不正与年龄、眼轴长度及角膜表面形态改变的关系。方法回顾性分析2017年3月—2019年12月在大连市某医院眼科门诊就诊的121例(242眼)儿童临床资料,根据年龄分为5~7岁组[48例(96眼)]、8~10岁组[43例(86眼)]、11~14岁组[30例(60眼)]。比较不同年龄及不同屈光度儿童的眼轴长度(AL)、角膜曲率,分析各年龄组屈光度与AL、角膜曲率的相关性。结果3组儿童眼睛角膜曲率比较,差异均无统计学意义(P>0.05);3组儿童眼睛屈光度比较,5~7岁组>8~10岁组>11~14岁组,差异均有统计学意义(P<0.05);3组儿童眼睛AL比较,5~7岁组<8~10岁组<11~14岁组,差异均有统计学意义(P<0.05);Pearson相关分析发现,年龄与屈光度呈负相关(r=-0.687,P<0.05),年龄与AL呈正相关(r=0.426,P<0.05)。不同年龄组不同屈光度儿童眼睛角膜曲率比较,差异均无统计学意义(P>0.05);各年龄组不同屈光度儿童眼睛AL比较,均为近视>正视>远视,差异均有统计学意义(P<0.05);Pearson相关分析发现,各年龄组儿童眼睛屈光度与AL均呈负相关(P<0.05)。结论随着年龄增加、眼轴增长,儿童屈光度逐渐降低,近视深度增加。临床应采取措施延缓儿童眼轴增长,以改善儿童屈光不正状态。Objective To investigate the interrelationship between age,axial length,corneal surface morphology changes anel refractive error in children aged 5 to 14 years.Methods The clinical data of 121 children(242 eyes)attending the ophthalmology clinic of a hospital in Dalian from March 2017 to December 2019 were retrospectively analyzed and divided into 48 cases(96 eyes)in the group of 5-7 years old,43 cases(86 eyes)in the group of 8-10 years old,and 30 cases(60 eyes)in the group of 11-14 years old according to their age.We compared the differences in AL and corneal curvature among children of different ages and different refraction levels and analyzed the correlation between refraction level and AL and corneal curvature in each age group.Results When comparing the corneal curvature of the eyes of the 3 groups of children,the differences were not statistically significant(P>0.05);when comparing the refraction level of the eyes of the 3 groups of children,the 5-7 years old group>the 8-10 years old group>the 11-14 years old group,and the differences were statistically significant(P<0.05);when comparing the AL of the eyes of the 3 groups of children,the 5-7 years old group<the 8-10 years old group<the 11-14 years old group,and the differences were statistically significant(P<0.05);Pearson correlation analysis revealed that age was negatively correlated with refraction level(r=-0.687,P<0.05)and positively correlated with AL(r=0.426,P<0.05).The differences were not statistically significant(P>0.05)when comparing the corneal curvature of the eyes of children with different refraction levels in different age groups;the differences were statistically significant(P<0.05)when comparing the AL of the eyes of children with different refraction levels in all age groups:myopia>orthopia>hyperopia;Pearson correlation analysis showed that the refraction level of the eyes of children in all age groups were negatively correlated with AL(P<0.05).Conclusion With the increasing age and eye axis growth,children's refractive error gradually d
