方法：挑选因CCh所致的以溢泪症状为主的患者共70例70眼，参照张氏分级标准分为Ⅱ，Ⅲ，Ⅳ级3组。所有患者采用普拉洛芬点眼2wk，根据症状、染料消失试验、苦味试验和泪膜破裂时间做各组治疗前后的疗效分析。

结果：普拉洛芬治疗后2wk，Ⅰ、Ⅱ级患者症状改善最明显，Ⅲ级次之，Ⅳ级最差； 染料消失试验Ⅱ级阳转率最高，Ⅲ级次之，Ⅳ级最少，三组之间有统计学差异(P<0.05)； Ⅱ级苦味试验时间较前缩短(P<0.05)，泪膜破裂时间较前延长(P<0.05)，而Ⅲ、Ⅳ级时间较前无改变(P>0.05)。

结论：普拉洛芬对结膜松弛症Ⅱ级所致的眼表泪液异常治疗有效。

METHODS: Seventy cases(70 eyes)whose the main symptoms was epiphora induced by CCh were divided into Ⅱ, Ⅲ and Ⅳ in 3 groups according to Zhang's grading standards, meanwhile, all the patients were treated with the eye drops of Pranoprofen for 2wk.
