To validate a visual acuity (VA) test application on touchpad in the screening of pediatric population by comparing VA results obtained with conventional tests.
A cohort of 101 patients, 44 girls and 57 boys with a median of 6.5 years old (3-10 years of age), presenting for eye examinations in Ophthalmology Department (Strasbourg, France) between November 1, 2018, and February 1, 2019 were enrolled. Monocular and binocular VA testing was performed on the subject using both a standard test and the touchpad application (Monoyer, "E" or, Pigassou depending of children's capacities). Patients were excluded if they were physically or mentally unable to use the touchpad. The duration of each tests, the painfulness, the comprehension, the attention of children during the test and test's preferences were also evaluated.
There was a good linear correlation and intra-class correlation coefficient [ICC=0.50 (0.34, 0.64) for binocular acuity, 0.74 (0.64, 0.82) for right eyes and 0.525 (0.37, 0.66) for left eye]. The standard errors of measurement were very low (0.08, 0.05, 0.08 for binocular VA, right eyes VA and left eyes VA, respectively). There was no difference between two tests for right eye (=0.126), left eye (=0.098) and binocular acuity (=0.085). Non inferiority was proved for all binocular [-0.06 (-0.09, -0.03)], right eye [-0.04 (-0.07, -0.01)] and left eye [-0.06 (-0.09, -0.02)] VA. The sensitivity and specificity, which correspond to the ability for our app to detect amblyopia, were 92% and 80% respectively.
Our touchpad application represents an efficient and valid test of VA in children with a high specificity to detect visual impairment.
通过比较传统视力测试所获结果，验证在儿童群体筛查中使用触摸板进行视力（VA）测试的应用程序。
纳入2018年11月1日至2019年2月1日期间在法国斯特拉斯堡眼科就诊接受眼部检查的101例患者，其中44例女孩，57例男孩，年龄中位数为6.5岁（3至10岁）。对受试者进行单眼和双眼视力测试，同时使用标准测试和触摸板应用程序（根据儿童能力选择莫诺耶“E”字表、皮加索视力表）。如果患者身体或精神上无法使用触摸板，则将其排除。还评估了每次测试的持续时间、疼痛程度、理解情况、测试过程中儿童的注意力以及对测试的偏好。
存在良好的线性相关性和组内相关系数[双眼视力的ICC = 0.50（0.34，0.64），右眼的ICC = 0.74（0.64，0.82），左眼的ICC = 0.525（0.37，0.66）]。测量的标准误差非常低（双眼视力、右眼视力和左眼视力分别为0.08、0.05、0.08）。右眼（P = 0.126）、左眼（P = 0.098）和双眼视力（P = 0.085）的两种测试之间无差异。所有双眼视力[-0.06（-0.09，-0.03）]、右眼[-0.04（-0.07，-0.01）]和左眼[-0.06（-0.09，-0.02）]的非劣效性得到证实。对应于我们的应用程序检测弱视能力的敏感性和特异性分别为92%和80%。
我们的触摸板应用程序是一种高效且有效的儿童视力测试，对检测视力损害具有高特异性。
