Abstract

Simple but effective tests have been produced for screening subjects with low vision in developing countries. These tests of distance and near vision, based on the E test, were evaluated and validated in trials with people aged 4-90 years, and have been field tested in the health, education and rehabilitation services in 32 developing countries. Their sensitivity and specificity as screening tools for low vision have been calculated; sensitivity of 85% and specificity of 96% for the distance vision test, and sensitivity of 100% and specificity of 84% for the near vision test. The content and format of the tests have been demonstrated to be appropriate for developing countries, and their effectiveness for screening for low vision has been confirmed.

摘要

针对发展中国家视力低下人群的筛查,已研发出简单却有效的测试方法。这些基于E视力表的远视力和近视力测试,在4至90岁人群的试验中进行了评估和验证,并已在32个发展中国家的卫生、教育和康复服务领域进行了实地测试。已计算出它们作为低视力筛查工具的敏感性和特异性;远视力测试的敏感性为85%,特异性为96%;近视力测试的敏感性为100%,特异性为84%。测试的内容和形式已证明适用于发展中国家,其在低视力筛查方面的有效性也得到了证实。
