摘要
目的分析儿童屈光状态与屈光要素的相关关系,了解屈光要素对儿童近视形成的可能影响,以期根据屈光要素对儿童的屈光状态进行预测。方法选取2008年暑假于我院眼科门诊顺序就诊的5～12岁儿童共32例(64只眼),经1%阿托品眼膏连续散瞳7d后验光测得屈光度,用A超及角膜曲率计测得屈光要素生物测量值。分析左右眼屈光要素的差别以及屈光要素间的相互关系,并用多元线性回归分析建立屈光度、相关屈光要素和生长发育因素间关系的回归方程。结果(1)右眼眼轴长于左眼眼轴、水平径角膜曲率右眼大于左眼,右眼的动态屈光度和静态屈光度均明显低于左眼(P<0.05);(2)在5～11岁时期,左右眼眼压与眼轴的增长基本一致;而12岁时,左右眼眼压与眼轴的增长出现相反的情况;(3)静态屈光度(D)与眼轴长度(AL)、角膜曲率均值(K)、身高(H)、年龄(AGE)间关系的多元线性回归方程为D=102.674-2.586×AL-1.288×K+13.127×H-0.440×AGE(R=0.928)。结论在同一个体,右眼的近视进展程度要早于或高于左眼,随着年龄的增加,眼压和眼轴的增长中存在"拐点",屈光状态与屈光要素间的匹配密切相关,5～12岁儿童的静态屈光度(D)可以根据眼轴(AL)、角膜曲率(K)、身高(H)和年龄(AGE)进行预测。
Objective To investigate the correlationship between children ametropia and refractive factors and predict the static diopter with the biometry data of refractive factors on the children. Methods Thirty-two children （ 16 boys, 32 eyes;16 girls, 32 eyes） ,aged 5 to 12 years old, were selected from outpatients at random. Static diopter was measured with cyclopegic retinoseopy after 1% Atropine applied for seven days successively. The physical dimensions from ultrasound and keratometry ,included axis length ,anterior chamber depth ,lens thickness ,vitreous length and corneal curvature radius. The difference between left and right eyes was analyzed. The data was analyzed with SPSS to sum up a multivariate linear regression formula that could express their quantitative relationship. Results （ 1 ） The axis length of right eyes was markedly higher than that of left eyes, the corneal curvature radius in horizontal meridian of right eyes was markedly higher than that of left eyes, beth dynamic diopter and static diopter of right eyes was remarkably less than those of left eyes （ P 〈 0.05 ） ; （ 2 ） During 5 to 11 years old, the increase of axis length and intraocular pressure was synchronous in both left and right eyes, but it was opposite in the two eyes at 12 years old; （3）The multivariate linear regression formula was D = 102. 674-2.586 ×AL-1.288 ×K＋13.127 ×H -0.440×AGE （R = 0.928）.Conclusion The progress ofmyopiain right eyes is earlier or higher than that in left eyes. During age increased, there is a turning point in the increase of axis length and intraocular pressure？. The static diopter of the children at age of 5 - 12 seems enable to be predicted through biometric data of axis length, corneal curvature radius, heightand age.
