Tear film flow and stability studies were carried out in patients suffering from cicatrizing trachoma by Schirmer test I and tear film break-up-time (BUT) measurements, respectively. Both Schirmer test I and BUT values were decreased significantly (t-test, P less than 0.001) depicting aqueous as well as mucin deficiency and hence, an unstable tear film in this condition.
通过泪液分泌试验I和泪膜破裂时间（BUT）测量，分别对患有瘢痕性沙眼的患者进行泪膜流动和稳定性研究。泪液分泌试验I和BUT值均显著降低（t检验，P<0.001），表明存在水样液和黏蛋白缺乏，因此在这种情况下泪膜不稳定。
