翼状胬肉切除联合自体结膜瓣移植术对泪膜泪液状态的影响

目的 分析研究翼状胬肉切除联合自体结膜瓣移植术对翼状胬肉患者泪膜泪液状态的影响。 方法 对65例翼状胬肉患者分别在术前3 d及术后7 d、术后1个月、3个月作泪膜泪液相关检查,包括泪膜破裂时间(BUT)、基础泪液分泌Ⅰ试验(SⅠ)及角膜荧光素染色(FL),并做对比分析。 结果 BUT及FL术前与术后不同时间对比,差异有统计学意义(P<0.05);SⅠ试验结果手术前后对比差异无统计学意义(P>0.05)。 结论 翼状胬肉切除联合带有角膜缘上皮的游离结膜瓣移植术可以有效改善翼状胬肉术后的泪膜泪液的功能。

Changes of tear film and tear secretion in patients before and after pterygial excision combined with conjunctival ;autografts

Objective To evaluate the changes of tear film and tear secretion in patients before and after pterygial exci-sion combined with conjunctival autografts.Methods Tear break-up time (BUT),SchirmerⅠtest (SⅠ)and corneal fluorescein staining (FL)were evaluated in 65 eyes of 65 patients suffered from pterygium 3 days before operation,and 7 days,1 month,and 3 months after pterygial excision combined with conjunctival autografts.Results The results of BUT and FL were significantly different before and after pterygial excision (P<0.05 ).No significant difference was found in SⅠ before and after surgery (P>0.05 ).Conclusion Pterygial excision combined with conjunctival auto-grafts can partly restore the ocular surface in patients with pterygium.
