A group of 10 subjects had their tears evaluated by the Schirmer and tear break-up time (TBUT) tests and their rate of tear evaporation measured by resistance hygrometry. No significant relation was found between the evaporation of the tears and the results obtained by either the Schirmer or the TBUT test. No correlation was found between the Schirmer and the TBUT test results. A significant increase in tear evaporation rate was however produced by the instillation of fluorescein during the TBUT test and by the application of Schirmer strips during the Schirmer test. It is concluded that the Schirmer and TBUT tests measure different features of the tears and these features are not related to the rate of tear evaporation.
一组10名受试者的眼泪通过Schirmer试验和泪膜破裂时间（TBUT）测试进行评估，并用电阻湿度测定法测量其泪液蒸发速率。泪液蒸发与Schirmer试验或TBUT测试所得到的结果之间未发现显著关联。Schirmer试验结果与TBUT测试结果之间也未发现相关性。然而，在TBUT测试期间滴入荧光素以及在Schirmer试验期间应用Schirmer试纸条会使泪液蒸发速率显著增加。得出的结论是，Schirmer试验和TBUT测试测量的是眼泪的不同特征，并且这些特征与泪液蒸发速率无关。
