This study compared the results of vision screening of 5 year olds in schools by school nurses and an orthoptist, compared two tests, and examined testing conditions. The specificity of nurse testing was 95% and the sensitivity 83%. No conclusions about the tests could be made owing to the small numbers in this part of the study, but some children, after nearly one year at school, could not match a line of four letters required for the more accurate test. Only 13 of 22 schools had suitable testing conditions.
本研究比较了学校护士和眼科矫正师对5岁儿童进行视力筛查的结果，对比了两项测试，并检查了测试条件。护士测试的特异性为95%，敏感性为83%。由于该研究此部分的样本数量较少，无法对测试得出结论，但一些孩子在入学近一年后，无法认出更精确测试所需的一行四个字母。22所学校中只有13所具备合适的测试条件。
