不同粘弹性物质对人工晶体植入术后角膜内皮细胞的形态影响

本研究使用角膜内皮分析系统，对使用空气泡、Ｈｅａｌｏｎ和２％荧光羟丙基甲基纠维素进行人工晶体植入术的病例进行角膜内皮细胞的形态学分析。术后短期内皮细胞丢失率，空气泡组显著高于后二组，而细胞面积变异系数（ＣＶ）和六边形细胞百分数（Ｈ％）在三红中都有相似的表现，即ＣＶ值在术后一周增加，但术后一月有恢复术前水平的趋势；Ｈ％值在术后一周降低，但术后一月回升到接近术前的水平。Ｈｅａｌｏｎ组和甲基纤维素组相比，细胞丢失率无显著差异。

酚红棉线试验在诊断干眼中与Schirmer＇sⅠ试验及BUT一致性的比较

目的：比较在诊断干眼方法中酚红棉线，Schirmer＇sⅠ试验及泪膜破裂时间测量泪膜的一致性。方法：110只白内障术眼术前分别用酚红棉线试验，Schirmer＇sⅠ试验测量泪液分泌量，两种方法间隔5min，然后均行泪膜破裂时间测定（break up time，BUT），所有资料均采用Kappa统计学方法，分析其一致性。结果：酚红棉线测量泪液分泌试验，棉线湿长〈10mm的患者．占总眼数的36．4％，湿长〈20mm者，占总眼数的89．1％；Schirmer＇sⅠ试验滤纸湿长〈5mm者，占总眼数的10．9％，湿长〈10mm者，占总眼数的40．0％。BUT〈5s者占总眼数的23.6％，〈10s者占总眼数的65．5％。酚红棉线试验与Schirmer＇sⅠ试验，BUT的一致性Kappa值分别为从0．03到0．29，从-0．028到0．13，酚红棉线试验与Schirmer＇sⅠ试验及BUT的一致性较差。同样Schirmer＇sⅠ试验与BUT的一致性Kappa值从0．12到0．31，两者的一致性较差。结论：酚红棉线试验与Schirmer＇sⅠ试验，BUT试验在测试泪液量方面的一致性较差，而且Schirmer＇sⅠ试验与BUT试验相比较一致性也较差，因此诊断干眼患者需要联合多种检查方法。     

大切口无缝线白内障(囊外)摘除术后泪膜变化的研究

Objective To investigate the alterations of tear film after sutureless large incision manual cataract extraction (SLIMCE). Methods SAw-eight eyes undergone SLIMCE operation were chosen ran-domly. Slit-limp microscope, break- up time (BUT), schirmmer Ⅰ test (Sit), FL were used to observe the alter-ations of tear film at different time points post-opcration. Impression cytology and microphoto-analyses tech-niques were also applied to observe the goblet cells at different time points post-operation. Results Subjective complaint of dry eye within 3 months after the operations were significantly increased compare with pre-opera-tions. The schirmmer Ⅰ test was greatly increased 2 weeks post operation,the mean scores of fluorescence in-creased and the mean break-up time decreased 1 month post operation (P <0.05 ). The impression cytology de-tection showed that the number of conjunetiva goblet cells in surgery area is lower at different time point post-operation respectively (29.62±4.31 ; 22.69±4.71 ; 39.05±4.27; 44.83±3.63; 45.76±3.55)than that in pre-operation (46.35±4.86 ) (P <0.05 ). Conclusion SLIMCE operation has effect on the stability of tear film.
