目的: 研究长期使用青光眼药物对病人眼表结构和功能的影响。方法: 将使用青光眼局部药物≥
3mo 的病人62 例( 92 只眼) ,分为A 组( 使用一种药物) : 1%毛果芸香碱8 例( 10 只眼) ,0.5%噻吗心安9 例( 12
只眼) ,0.2%阿法根7 例( 14 只眼) ,1%派立明8 例( 12 只眼) 和B 组( 使用两种及以上药物) : 1%毛果芸香碱+
1%派立明9 例( 15 只眼) ,5%噻吗心安+0.2%阿法根15 例( 21 只眼) ,1%毛果芸香碱+1%派立明+0.2%阿法根6
例( 8 只眼) ,选择健康志愿者30 例( 30 只眼) 为对照组,对所有观察对象进行基础泪液分泌试验( SIt) 、泪膜破裂
时间( BUT) 测定、角膜荧光染色( FL) 及结膜印记细胞学检查( CIC) 。结果: A 组SIt( 8.51±4.76) mm/5min,BUT
( 8.46±4.24) s,FL 评分为( 2.91 ± 1.03) ; B 组ST( 6.34 ± 2.05) mm/5min,BUT ( 6.38 ± 2.23) s,FL 评分为( 3.84 ±
1.14) ; 对照组SIt( 10.72±4.62) mm/5min,BUT( 11.45±5.12) s,FL 评分为( 0.62±0.04) ,三组两两相比差异都具有
统计学意义( F= 21.763,P= 0.000; F= 18.848,P= 0.000; F= 25.418,P= 0.000) 。A 组和B 组CIC 评级为Ⅱ~Ⅲ级,
比例为45.83%和68.18%,高于对照组的6.67%( X= 28.266,P = 0.000) 。结论: 长期局部使用抗青光眼药物,会造
成泪液分泌减少、泪膜破裂时间缩短以及结膜杯状细胞减少,从而破坏泪膜稳定性造成眼表面损伤,增加用药种
类会加重这种损害。

Objective: To study the effects of long-time local glaucoma agents on the ocular surface
structure and function in glaucom patients.Methods: 62glaucoma patients( 92eyes) with local glaucoma
agents for 3months were divided into group A( one kind of glaucoma agents) consists of1%Pilocarpine
in 8 cases( 16eyes) ,0.5%Timolol in 9 cases( 12eyes) ,0.2%Alphagan in 7 cases( 14eyes) ,1
%Brinzolamidein 8 cases( 12eyes) ,and group B( two kinds of glaucoma agents) consists of1%Pilocarpine +1%
brinzolamide in 9 cases( 15eyes) ,5%Timolol +0.2%Alphagan in 15 cases( 21eyes) and1%Pilocarpine
+1%Azopt+0.2%Alphagan in 6 cases( 8eyes) ,and selected 30 healthy volunteers( 30eyes) as the control
group,compared Schirmer test I( ST) , tear film break-up time( BUT) ,corneal fluorescein staining
( FL) and conjunctival impression cell( CIC) Rating.Results: A group SIt was( 8.51±4.76) mm/5min,
BUT was( 8.46±4.24) s,FL score was( 2.91±1.03) ; B group ST was( 6.34±2.05) mm/5min,BUT was
( 6.38±2.23) s,FL score was( 3.84±1.14) ; Control group SIt was( 10.72±4.62) mm/5min,BUT was
( 11.45±5.12) s,FL score was( 0.62±0.04) .The difference between the three groups was statistically
significant( F = 21.763,P = 0.000; F = 18.848,P = 0.000; F = 25.418,P = 0.000) .CIC Rating of A and B
groups were Ⅱ~ Ⅲ and the ratio is 45.83%and 68.18%,which was higher than that of the control
group 6.67%( X2 = 28.266,P = 0.000) .Conclusion: long-term local glaucoma agents lead to tear secretion
decreased, tear break-up time shortened,and conjunctival goblet cells reduced,which destroy the
stability of tear film caused by ocular surface injury.Increaseing the types of drugs will aggravate the
damage.
