摘要
目的:探讨干眼症患者泪液清除荧光素钠溶液的速率变化。方法:选取干眼症患者30例,将20g/L荧光素钠溶液6μL一次滴入下结膜囊内,在裂隙灯下观察结膜囊内泪液中荧光素钠的消失时间,并与同期正常30人对照。结果:本组干眼症患者泪液荧光素钠的清除时间右眼为2229.18±488.37s,左眼为2239.71±478.99s。正常人泪液荧光素钠的清除时间右眼为1173.35±161.79s,左眼为1188.92±200.32s。经Origin6.0统计软件分析,两组间存在显著性差异(P<0.01)。结论:干眼症患者泪液清除荧光素钠的时限较正常人明显延长。干眼症患泪液清除时间的延长是干眼症发病机制中的一种补偿机制,对干眼症患者有益。
AIM：To explore the speed diversity of lacrimal fluid clearance of fluorescein sodium in dry eye patient.METHODS：Totally 30 cases of dry eye patient were chosen,6μL of 20g/L Fluress was dropped in their conjunctival sac.The extinction time of fluorescein sodium in it was observed unde slit-lamp and compared with that in 30 cases of normal people.RESULTS：The extinction time of fluorescein sodium in right eye of dry eye patient was 2229.18±488.37s and that in left eye was 2239.71±478.99s.The extinction time of fluorescein sodium in right eye of normal people was 1173.35±161.79s and that in left eye of was 1188.92±200.32s.There was statistical significant difference between the two groups by analysis using Origin 6.0 statistics software（P0.01）.CONCLUSION：The extinction time of fluorescein sodium in dry eye patient was prolonged than that in normal people.The extension is a compensation mechanism which can benefit patients.
