Abstract
目的:探讨局部应用抗青光眼药物曲伏前列素滴眼液对患者泪膜功能的影响。
  方法:选取原发性开角型青光眼或高眼压患者18例32眼。患者均局部用曲伏前列素滴眼液,每晚滴1次。用药前及用药后1,2,3 mo行症状评分及基础泪液分泌量测定( SchirmerItest , SIt )、角膜荧光素染色( corneal fluorescein staining,FL)、泪膜破裂时间(tear break-up time, BUT)。
  结果:全部患者用药前患者症状评分、FL的平均值为1.34±1-56,0.44±0.73,用药后1,2,3mo 分别为2.75±1.63,1-08±0.84;5.10±1.68,1.53±0.67;6.33±1.40,1.98±0-50。用药后1,2,3 mo患者症状评分、FL均显著高于用药前(P=0.00),且逐渐增加。全部患者用药前患者症状BUT,SIt 的平均值为(7.76±0.92s),(8.47±2.73mm/5min),用药后1,2,3mo 分别(7.08±1.15s),(7.73±3-44mm/5min);(5.59±1.33s),(6.82±3.05mm/5min);(4.29±1.87s),(6.04±3.15mm/5min)。用药后1,2,3mo患者BUT 值和 SIt 值均显著低于用药前水平( P=0-00),且逐渐减低。
  结论:短期使用曲伏前列素滴眼液即加重患者角膜刺激症状,泪膜稳定性下降,泪液分泌减少。
