Abstract

Background: New photoscreening models promise to detect amblyopia risk factors early in hopes of reducing permanent pediatric monocular and binocular vision impairment. The 3 commercially available interpreted photoscreeners had not yet been compared.

Methods: This is a prospective, observational screening study following AAPOS guidelines on pediatric patients with and without developmental delays. 270 patients in a pediatric eye practice aged 4.7 +/- 4 years with 7% special needs. From December 2011 through March 2012, the Plusoptix, the iScreen, and the Pediavision SPOT were applied before confirmatory exam in a clinical pediatric eye practice.

Results: The inconclusive rate ranged from 1-4% (iScreen) to 12% (Plusoptix). Sensitivity ranged from 72% (iScreen) to 84% (Plusoptix) and specificity ranged from 68% (SPOT) to 94% (Plusoptix). The iScreen can provide results in 99% of high risk patients.

Conclusions: In this cohort with high pre-screening prevalence, the 2011 photoscreeners had favorable validation that is expected to improve with further clinical study. Pediatricians have practical technology with a recognized procedure code to assist in amblyopia reduction.

2012: Plusoptix、Iscreen和SPOT在高危患者中的儿童照相筛检比较研究。

背景:新的光筛查模型有望早期发现弱视的危险因素，以期减少儿童永久性单眼和双眼视力障碍。目前还没有对3种市售的解释光筛进行比较。方法:这是一项前瞻性、观察性筛查研究，遵循AAPOS指南，对有或无发育迟缓的儿科患者进行筛查。270例儿童眼科患者，年龄4.7±4岁，7%有特殊需求。从2011年12月到2012年3月，Plusoptix, iScreen和Pediavision SPOT在临床儿科眼科实践中应用于确认性检查之前。结果:不确定率为1-4% (iScreen) ~ 12% (Plusoptix)。灵敏度从72% (iScreen)到84% (Plusoptix)，特异性从68% (SPOT)到94% (Plusoptix)。iScreen可以为99%的高风险患者提供结果。结论:在这个筛查前患病率较高的队列中，2011年photoscreeners获得了良好的验证，并有望在进一步的临床研究中得到改善。儿科医生有实用的技术和公认的程序代码来帮助减少弱视。
