该研究通过泪水干涉量度分析法探讨正常人眼在滴注3%diquafosol滴眼液后泪膜脂质层厚度(LLT)是否会增加。

47名健康男性(平均年龄为42.4岁)随机接受单眼人工泪液或3%diquafosol滴眼液1滴,滴注后的15、30、60分钟,通过泪水干涉量度分析法分别对双眼LLT进行量化,并评估滴注30分钟前、后的眼部症状。LLT基线水平、泪膜破裂时间(TBUT)、上下眼睑的睑板腺区、Schirmer检测值分别在滴注前的不同日期内进行过检测。

结果发现,滴注前、滴注后15、30、60分钟LLT分别为62.3±31.1、77.0±39.5、79.3±40.5、77.7±43.6nm,并且,由diquafosol滴眼液引起的LLT增加在每个时间点都表现非常显着。人工泪液并不能明显的导致LLT的增加。TBUT(rho=0.32,P=0.026)下眼睑的睑板腺区(rho=-0.33,P=0.022),在diquafosol滴注组中发现,diquafosol滴注前后LLT的最大差异(DeltaLLTmax)与LLT的基线水平明显相关。年龄与LLT基线水平或DeltaLLTmax无关,且两滴注组中眼部症状无差异。

局部3%diquafosol滴眼液滴注能使任何年龄段的正常人眼LLT增加长达60分钟。
