结膜松弛症术后干眼改变

目的探讨结膜松弛症术后的泪液学变化。方法对29例（32眼）结膜松弛症新月形球结膜切除，分别于术前和术后3个月进行症状评估、裂隙灯显微镜检查、泪河观察、SchirmerI试验、泪膜破裂时间（BUT）、眼表荧光素染色、以及泪液清除率（TCR）对比分析。结果症状改善者29眼（90．63％），泪河高度恢复正常28眼（87．50％），Schirmer I试验手术前后差异无统计学意义（P〉0．05），BUT和眼表荧光素染色评分术后较术前差异有统计学意义（P〈0．05），荧光素清除试验恢复正常31眼（96．88％）。结论手术切除松弛多余结膜组织可以明显改善结膜松弛症的干眼症状以及泪液动力学改变。

The changges in dry eye after conjuctivochalasis surgery

Objective To investigate the lacrimal fluid after conjuetivochaiasis surgery. Methods A total 32 eyes of 29 conjunctivochalasis patients were enrolled in this study. Each eye had received the redundant conjunctiva operation. The evaluation was based on ： symptons of patients, slit lamp examination, observation of tear meniscus,Sehirmer I test,tear break-up time （BUT）, Ocular surface fluorescence staining, and tear clearance rate （TCR）. All the examinations were performed in the preoperative and postoperative three months. Results 29 eyes （90. 63% ） had improved symptoms. The hight of tears river in 28 eyes （ 87. 5 % ） return to normal. There was no significant differences （ P 〉 0.05 ） between Sehirmer I tests results before and after surgery. BUT and ocular surface fluorescence staining scores were significantly improved after the operation compared with that before the operation （P 〈 0. 05 ）, fluorescent-clearance pilot returned to normal in 31 eyes （96. 88% ）. Conclusion This study suggested that resection of unnecessary conjunctival organizations is very effective in resolving patients complaints and improving tear dynamics in conjunetivochalasis with dry eye.
