Abstract

PURPOSE

To test the accuracy and reliability of the plusoptiX A12 in detecting amblyogenic risk factors.

METHODS

We prospectively collected data on children undergoing screening with the plusoptiX A12, cycloplegic refraction, and complete ophthalmic examination. American Association for Pediatric Ophthalmology and Strabismus (AAPOS) 2013 guidelines for the detection of amblyogenic risk factors were used for plusoptiX A12 screening and comparison of the results of both examination modes.

RESULTS

Data on 402 eyes of 201 children (mean age, 7.63 ± 3.41 years) was collected. Mean (with standard deviation) cycloplegic refraction results were as follows: sphere, 0.88 ± 1.5 D; cylinder, -0.61 ± 0.74 D; axis, 71.17 ± 71.04; and spherical equivalent, 0.68 ± 2.63. The plusoptiX A12 measurements were as follows: sphere, 0.58 ± 1.4 D; cylinder, -0.66 ± 0.77 D; axis, 77.3 ± 68.9; and spherical equivalent, 0.25 ± 1.3. We found a strong correlation (Pearson) for sphere (r = 0.91), cylinder (r = 0.81), and axis (r = 0.7). The mean difference of the myopic spherical component between the plusoptiX and cycloplegic refraction was -0.048 ± 0.55 (95% LoA, +1.04 to -1.14 D); for the hyperopic spherical component, 0.37 ± 0.93 (LoA, +2.20 to -1.45 D); and for the cylindrical component, 0.05 ± 0.32 (LoA, +0.68 to -0.57D). The sensitivity, specificity, positive and negative predictive values for myopia were, respectively, 86%, 93%, 82%, and 94%; for astigmatism, 85%, 98%, 88% and 98%; and for hyperopia, 40%, 100%, 100%, and 98%.

CONCLUSIONS

The plusoptiX A12 accuracy is high in all subgroups but better in the myopic, astigmatic, and anisometropic subgroups. Reliability was lower in the hyperopic eyes, possibly resulting in underestimation of hyperopic refractive error.

摘要

目的

测试PlusoptiX A12在检测弱视危险因素方面的准确性和可靠性。

方法

我们前瞻性地收集了接受PlusoptiX A12筛查、睫状肌麻痹验光和全面眼科检查的儿童的数据。采用美国小儿眼科与斜视学会（AAPOS）2013年弱视危险因素检测指南对PlusoptiX A12进行筛查，并比较两种检查模式的结果。

结果

收集了201名儿童（平均年龄7.63±3.41岁）402只眼的数据。睫状肌麻痹验光结果的平均值（及标准差）如下：球镜度数，0.88±1.5D；柱镜度数，-0.61±0.74D；轴位，71.17±71.04；等效球镜度数，0.68±2.63。PlusoptiX A12的测量结果如下：球镜度数，0.58±1.4D；柱镜度数，-0.66±0.77D；轴位，77.3±68.9；等效球镜度数，0.25±1.3。我们发现球镜度数（Pearson相关系数r=0.91）、柱镜度数（r=0.81）和轴位（r=0.7）之间存在强相关性。PlusoptiX与睫状肌麻痹验光之间近视球镜成分的平均差值为-0.048±0.55（95%一致性界限，+1.04至-1.14D）；远视球镜成分的平均差值为0.37±0.93（一致性界限，+2.20至-1.45D）；柱镜成分的平均差值为0.05±0.32（一致性界限，+0.68至-0.57D）。近视的敏感度、特异度、阳性预测值和阴性预测值分别为86%、93%、82%和94%；散光的分别为85%、98%、88%和98%；远视的分别为40%、100%、100%和98%。
