BACKGROUND
The Medical Technology Inc (MTI) Photoscreener is a new eccentric photoscreener that is being marketed as a device for the detection of amblyogenic factors in preverbal children. The purpose of this study was to evaluate the accuracy of the MTI Photoscreener in the target population of young, healthy children.
METHODS
One thousand and three healthy children between the age of 6 months and 59 months were photoscreened with the MTI Photoscreener. Nine hundred and forty nine children were included in the study and their results were compared with a complete ophthalmologic examination with cycloplegia.
RESULTS
The sensitivity of the MTI Photoscreener was determined to be 81.8% with a specificity of 90.6%. The overall agreement rate was 88.8%. The positive and negative predictive values were 68.9% and 95.2%, respectively. All cases of strabismus and media opacities were detected.
CONCLUSION
The MTI Photoscreener is an accurate and reliable device designed to detect amblyogenic factors in young children. The camera offers promise as a useful mass-screening tool.
背景
医学技术公司（MTI）照片筛选仪是一种新型的偏心照片筛选仪，作为一种用于检测学语前儿童致弱视因素的设备进行销售。本研究的目的是评估MTI照片筛选仪在年轻健康儿童目标人群中的准确性。
方法
使用MTI照片筛选仪对1003名年龄在6个月至59个月之间的健康儿童进行照片筛选。949名儿童纳入研究，其结果与散瞳后的全面眼科检查结果进行比较。
结果
MTI照片筛选仪的敏感性为81.8%，特异性为90.6%。总体一致率为88.8%。阳性和阴性预测值分别为68.9%和95.2%。所有斜视和介质混浊病例均被检测到。
结论
MTI照片筛选仪是一种准确可靠的设备，旨在检测幼儿的致弱视因素。该相机有望成为一种有用的大规模筛查工具。
