To determine the sensitivity and specificity of school nurse screening for hypermetropia and convergence insufficiency exophoria (CIE) in schoolchildren.
Near point of convergence and distance visual acuity with +2.00D lenses were measured in 2097 children (6-15 years) during standard school nurse screening in the municipality of Randers, Denmark. One hundred and ninety-four children with positive screening results (near point of convergence >10 cm and/or distance visual acuity improved or maintained with +2.00D) and 182 controls with negative screening results received a full vision assessment, including cycloplegic refraction and orthoptic evaluation.
Sensitivity and specificity of screening was 0.75 and 0.69 for CIE and 0.59 and 0.87 for hypermetropia (≥+2.00), respectively. While precision of screening for CIE was significantly higher for symptomatic children aged 9-15 than for younger and asymptomatic children, precision of screening for hypermetropia was independent of age and presence of visually related symptoms.
While precision of screening for CIE and hypermetropia (>+2.00) was low, additional vision evaluation of children older than 9 years with asthenopic symptoms identified most children with CIE with a low absolute number of false positives.
为了确定学校护士在儿童中筛查远视和集合不足外斜视(CIE)的敏感性和特异性。
在丹麦兰讷斯市的标准学校护士筛查中,对 2097 名儿童(6-15 岁)进行了集合近点和远距视力+2.00D 镜片测量。对 194 名筛查结果阳性(集合近点>10cm 和/或远距视力提高或维持+2.00D)和 182 名筛查结果阴性的儿童进行了全面视力评估,包括睫状肌麻痹验光和斜视评估。
筛查对 CIE 的敏感性和特异性分别为 0.75 和 0.69,对远视(≥+2.00)的敏感性和特异性分别为 0.59 和 0.87。虽然 9-15 岁有症状儿童的 CIE 筛查准确性明显高于年龄较小和无症状儿童,但远视筛查的准确性与年龄和视力相关症状的存在无关。
虽然 CIE 和远视(>+2.00)筛查的准确性较低,但对 9 岁以上有视疲劳症状的儿童进行额外的视力评估,可以识别出大多数患有 CIE 的儿童,假阳性的绝对数量较少。
