目的 探讨SureSight手持验光仪在3～6岁儿童屈光不正筛查中的应用价值.方法 横断面研究.对徐汇区康健街道内321例经初步筛查后视力可疑低常儿童,进行非睫状肌麻痹下SureSight手持式验光仪及睫状肌麻痹下Topcon台式验光仪检查.将所得检测结果进行Bland-Altman相关性检验,并利用ROC曲线计算SureSight屈光不正筛选标准以进行诊断性试验评价.结果 非睫状肌麻痹下SureSight验光测得的球镜度、柱镜度及SE均与睫状肌麻痹下Topcon验光仪所测得相应度数差异有统计学意义,在测量结果上两者有中度(球镜度:r=0.59,P＜0.05;SE:r=0.54,P＜0.05)到高度(柱镜度:r=0.89,P＜0.05)相关性.进一步以散瞳后Topcon测量值为金标准作ROC曲线,发现当SureSight SE测量值≤+1.13 D时,可划定为可疑近视,SE测量值≥+1.44 D时,划定为可疑远视,散光测量值≥0.88 D时,划定为可疑散光.散光、近视及远视的Youden指数分别为0.679、0.298及0.270.结论 3～6岁儿童非睫状肌麻痹下SureSight检测结果在散光的筛查中具有一定的临床意义,可协助划定可疑参考值范围,操作方便.但用于近视以及远视的筛查界定有一定的局限性.

Objective To assess the value of the hand-held autorefractor SureSight in screening refractive errors in children 3 to 6 years old.Methods In a cross-sectional study,321 children with lower visual acuity than normal participated in the SureSight and Topcon examinations,under cycloplegic and non-cycloplegic conditions respectively.Data were evaluated with Bland-Altman and ROC based on the prevalence study.Results In the comparison,it was found that the differences in spherical diopter,cylinder diopters and spherical equivalent (SE) between non-cycloplegia with SureSight (S1) and cycloplegia with Topcorn (T2) were significant.The correlation between S1 and T2 ranged from moderate (spherical diopter:r=0.59,P＜0.05; SE:r=0.54,P＜0.05) to high (cylinder diopter:r=0.89,P＜0.05).The ROC curve found that myopia,hyperopia and astigmatism suspects with S1 were ≤+1.13 D,≥+1.44 D and ≥ 0.88 D when compared to T2.The Yonden index also showed better sensitivity and specificity for astigmatism (0.679) than myopia (0.298) and hyperopia (0.270).Conclusion As a vision screening technique to detect refractive errors in preschool children,SureSight can help identify suspected astigmatism,but had limitations for myopia and hyperopia.
