摘要
目的分析儿童屈光不正在发育过程中的特性，探索以屈光要素测量值对5～13岁儿童的屈光状态进行预测分析。方法选取2011年1月至2012年9月于该院眼科门诊就诊的5～13岁儿童共461例（922只眼），经1％阿托品眼用凝胶连续散瞳5d后验光测得静态屈光度，并用角膜曲率计和A超测得各屈光要素测量值，同时测量身高、体质量参数并记录优势眼，分析儿童屈光不正在发育过程中的特性，并用多元逐步回归分析建立静态屈光度与相关屈光要素测量值及生长发育因素间关系的预测方程。结果（1）右眼静态屈光度的近视化程度较左眼明显（P〈0．05）；左眼为优势眼组中，左右眼各屈光要素比较，差异无统计学意义（P〉0．05）；右眼为优势眼组中，除右眼水平径角膜曲率大于左眼（P〈0．05），其余各值左右眼差异无统计意义（P〉0．05）。（2）在5～13岁，女生的近视进展趋势要早于男生。（3）儿童的眼轴长度（AL）和身高（H）密切相关，AL=16．135＋0．052×H（R=0．993）。（4）静态屈光度（D）与角膜曲率均值（K）、AL间关系的多元线性回归方程：D=84．271—0．937×K-1．878×AL（R=0．871）。结论眼轴长度和身高发育密切相关，5～13岁儿童的静态屈光度可以根据角膜曲率均值与眼轴长度进行预测。
Objective To investigate the characteristics of children ametropia in the development process,predict and analyze the refractive state with the measurement data of refractive factors on the children aged from 5 to 13 years old. Methods 461 children （922 eyes）,aged from 5 to 13 years old,were selected from outpatients who went to ophthalmology clinic from January 2011 to September 2012. The static diopter was measured by the optometry with the continuous mydriasis of 5 days using the ophthalmic gel of 1 %atropine. And the biological measured values of refractive factors were obtained by the A type ultrasonic and keratome- ter. Meanwhile, the parameters including the height（ H）, weight and the dominant eye were recorded to analyze the characteristics of children ametropia in the development process,and then the equation between the diopter and the correlative factors including the measurement data of refractive factors and growth factors was established by the stepwise multiple regression analysis. Results （1） The myopia degree of the right eye static diopter was significantly deeper than the left（P〈0.05）. In the group in which the left eye was dominant,the difference of the left eye and right eye refractive factors was not statistically significant（P〈0.05）. In the group in which the right eye was dominant, the difference of the left eye and right eye refractive factors was not statistically significant （P〉0. 05） except the instance in which K1 of the right eye was bigger than the left eye（P〈0.05）. （2） In the period of 5 to 13 years old,the myopia developing trend of girls was earlier than boys. （3） The ocular axis length（AL） and H development had a close relationship, and the correlation equation of them was AL= 16. 135＋0. 052 H （r= 0. 993）. （4） The multiple linear regression equation for the relationship between the static diopter（D） ,ocular AL and mean value of the corneal curvature（K） was D-84. 271 -0. 937K-1. 878AL（r=0. 871）. Conclusion The ocular AL and H development of children have a close relationship. The static diopter（D） of the children aged from 5 to 13 years old can be predicted by the ocular axis length（AL） and corneal curvature（K）, which can be used to prevent myopia reasonably.
