In most parts of the world, the Schirmer test (ST) is still the main test used by optometrists for the assessment of tear adequacy in the screening of potential contact lens wearers and as an aid in the diagnosis of "dry" eye. We tested the reliability of a 1-min ST in nine normal Hong Kong-Chinese (HK-Chinese) subjects during five to seven visits over a period of 2 weeks. For 4 of the subjects, the test consistently measured 0 mm/1 min, and 68% of the test results were less than 6 mm/1 min, a value suggested as the lower limit for normal asymptomatic eyes. The results obtained were inconsistent and it is concluded that the ST is unreliable and of little clinical value in this population.
在世界大部分地区，施密特试验（ST）仍是验光师用于评估潜在隐形眼镜佩戴者泪液充足情况以及辅助诊断“干眼症”的主要检测方法。我们在2周内对9名正常的香港华人（HK-Chinese）受试者进行了5至7次就诊，测试了1分钟ST的可靠性。其中4名受试者的测试结果始终为0毫米/1分钟，68%的测试结果小于6毫米/1分钟，而该数值被认为是正常无症状眼睛的下限。所获得的结果不一致，得出的结论是，在这一人群中，ST不可靠且临床价值不大。
