PURPOSE
New objective photoscreeners are emerging with encouraging national guidelines and pediatric providers can be reimbursed for photoscreening.
METHODS
Nine objective screeners were applied to two emmetropic subjects with or without known power contact lenses to induce spherical and cylindrical anisometropia close to American Association for Pediatric Ophthalmology and Strabismus (AAPOS) thresholds.
RESULTS
The screeners produced near linear pupil crescents and estimated refractions for induced anisometropia. Most performed well with AAPOS 2003 validation; however, the iPhone (Apple, Cupertino, CA) was too sensitive, whereas the remote autorefractors using Vision in Preschoolers Study criteria were less sensitive.
CONCLUSIONS
The new, interpreted objective screeners appear valid for detection of anismetropia.
目的
新型客观验光仪不断涌现，且有令人鼓舞的国家指南，儿科医疗服务提供者进行验光筛查可获得报销。
方法
对两名正视眼受试者应用九种客观验光仪，这两名受试者佩戴或不佩戴已知屈光度的隐形眼镜，以诱发接近美国小儿眼科与斜视协会（AAPOS）阈值的球镜和柱镜性屈光参差。
结果
验光仪产生了近似线性的瞳孔新月形，并对诱发的屈光参差进行了屈光度估算。大多数验光仪在AAPOS 2003验证中表现良好；然而，苹果手机（苹果公司，加利福尼亚州库比蒂诺）过于敏感，而使用学龄前儿童视力研究标准的遥控自动验光仪则不太敏感。
结论
新型的、经过解读的客观验光仪似乎可有效检测屈光参差。
