摘　　要：目的 分析小学一年级新生屈光状态指标球镜、等效球镜、轴率比及裸眼远视力相关性,明确各屈光状态指标在屈光筛查近视诊断中的一致性。方法 观察性研究。收集新疆沙湾市某小学一年级新生屈光筛查数据共369例(右眼369眼,左眼369眼),年龄(6.33±0.49)岁,其中男生187例(50.68%),女生182例(49.32%)。对屈光筛查数据中的裸眼远视力(UCDVA)、球镜度(DS)、等效球镜度(SE)、轴率比(AI/CR)进行相关分析。结果 男女生UCDVA、DS、SE、AL/CR间差异均无显著性(P>0.05)。UCDVA与DS、SE呈弱正相关(r=0.20,P<0.001;r=0.31,P<0.001),与AL/CR呈弱负相关(r=-0.21,P<0.001)。DS与AL/CR呈弱负相关(r=-0.38,P<0.001),SE与AL/CR呈中度负相关(r=-0.41,P<0.001),DS与SE呈强正相关(r=0.93,P<0.001)。结论 DS、SE值下降,AL/CR升高,均可引起近视的发生发展和UCDVA的下降。三项屈光状态指标在屈光筛查近视诊断中具有较好一致性。Objective Analysis of index of refractive status correlation with uncorrected distance visual acuity in first-grade pupils,in order to clarify the consistency of refractive status in the diagnosis of myopia in refractive screening.Methods Observational study.The data were collect from a primary school in Sha Wan,Xinjiang A total of 369 first-grade pupils age(6.33±0.49)were collected and out of which 187(50.68%)were male and 182(49.32%)were female.To observe the refractive screening data include uncorrected distance visual acuity(UCDVA),spherical diopters(DS),spherical equivalent(SE),the axial length/corneal radius of curvature ratio(AL/CR)of the pupils and analysis the index of refractive screening data each other.Results Comparative analysis of data differences in different sex of UCDVA、DS、SE and AL/CR were not statistically significant(P>0.05).The correlation coefficients of UCDVA and DS,SE were positive weak correlation(r=0.20,P<0.001;r=0.31,P<0.001);The correlation coefficients of UCDVA and AL/CR were negative weak correlation(r=-0.21,P<0.001).The correlation coefficients of DS and AL/CR were negative weak correlation(r=-0.38,P<0.001),The correlation coefficients of SE and AL/CR were negative moderate correlation(r=-0.41,P<0.001).The correlation coefficients of DS and SE were positive strong correlation(r=0.93,P<0.001).Conclusion The vaule of DS,SE decrease and AL/CR rise,all can cause the myopia progress and UCDVA decrease.There were better consistency in the myopia dagnosis of refractive screening for the three index.
