Our previous study of the plusoptiX S04 photoscreener included children ages 6 months to 16 years and allowed us to modify the referral criteria retrospectively to improve specificity and sensitivity. In this study we used the new referral criteria and tested children ages 3 to 5 years, a more appropriate range for a pediatric vision screening program.
A total of 153 children were examined consecutively. Each patient was screened with the plusoptiX S04 photoscreener on the same day as part of a comprehensive pediatric ophthalmology examination.
Fifty-three percent of the patients were found to have amblyopia or amblyopia risk factors during the pediatric ophthalmology examination. By using these results as our standard, we calculated that the plusoptiX S04 photoscreener offered a sensitivity of 99%, specificity of 82%, false-positive rate of 18%, and false-negative rate of 1.2%. These findings were similar to the results we achieved in our previous study with a broader age range.
The plusoptiX S04 is an automated photoscreening device that takes multiple images in less than 30 seconds, determining a noncycloplegic refraction. Sensitivity and specificity suggests that testing the plusoptiX S04 for applications in a general screening environment should be considered.
我们之前对plusoptiX S04电脑验光仪的研究涵盖了6个月至16岁的儿童，并使我们能够回顾性地修改转诊标准以提高特异性和敏感性。在本研究中，我们使用了新的转诊标准，并对3至5岁的儿童进行了测试，这一年龄范围对于儿科视力筛查项目更为合适。
连续检查了153名儿童。每位患者在同一天接受plusoptiX S04电脑验光仪筛查，作为综合儿科眼科检查的一部分。
在儿科眼科检查中，发现53%的患者患有弱视或有弱视危险因素。以这些结果作为我们的标准，我们计算出plusoptiX S04电脑验光仪的敏感性为99%，特异性为82%，假阳性率为18%，假阴性率为1.2%。这些发现与我们之前在更广泛年龄范围内的研究结果相似。
plusoptiX S04是一种自动电脑验光设备，可在不到30秒的时间内拍摄多张图像，确定非散瞳验光结果。其敏感性和特异性表明，应考虑测试plusoptiX S04在一般筛查环境中的应用。
