目的评价Plusoptix S04数码照相筛查仪在学校筛查项目中的诊断准确性。方法2006~2007年间，向当地学区幼儿园全体学生发送1343份资料小册子/同意书。当地一家公共卫生单位的助手拍摄了307名儿童。其中，271名儿童接受了由医生进行的独立眼科检查。将摄片结果与眼科检查结果进行比较。弱视危险因素定义为屈光参差1D(球面或柱面)、散光1.25D、近视3D、远视3.5D、任何明显斜视和任何媒体遮盖。检测弱视危险因素的灵敏度为83%，特异度为95%。阳性预测值为73%，阴性预测值为97%。无法测试/不可用的比率为1%。结论这些结果与以前报道的(但已不再可用的)数码照片筛选相机相比是有利的，也优于其他需要人工解释的离轴照片筛选设备的结果。根据这些结果，在现实世界的筛选程序中，摄像机会错误地引用4%的筛选者，而不会正确引用2%。Plusoptix S04相机在检测弱视风险因素方面的准确性似乎足够高，可以考虑将其进一步部署到广泛的学校筛查计划中。(美国AAPOS杂志2009；13：51-57)
PURPOSE To evaluate the diagnostic accuracy of the plusoptiX S04 digital photoscreener in a school screening program.METHODS Between 2006 and 2007, 1343 information pamphlets/consent forms were sent to all junior kindergarten students in a local school district. Assistants from a local public health unit photographed 307 children. Of these, 271 children received an independent ophthalmic examination by a physician. Photographic results were compared with the those of the ophthalmic examination. Amblyopia risk factors were defined as anisometropia >1 D (sphere or cylinder), astigmatism >1.25 D, myopia >3 D, hyperopia >3.5 D, any manifest strabismus, and any media opacity.RESULTS Photographic and examination results agreed in 94% of cases. Sensitivity in detecting amblyopia risk factors was 83%; specificity was 95%. The positive and negative predictive values were 73% and 97%, respectively. The untestable/unusable rate was 1%.CONCLUSIONS These results compare favorably with a previously reported (but no longer available) digital photoscreening camera and are superior to results obtained with other off-axis photoscreening devices that require human interpretation. On the basis of these results, in a real-world screening program, the camera would falsely refer 4% of those screened and would fail to correctly refer 2%. The accuracy of the plusoptiX S04 camera in detecting amblyopia risk factors appears sufficiently high to consider its further deployment in a widespread school screening program.
