摘要
为探讨小梁切除术中应用丝裂霉素Ｃ（ＭＭＣ）致前房出血的原因。方法：回顾性分析９９例１４２眼原发性青光眼小梁切除术后前房出血的情况，对术中未应用ＭＭＣ与术中巩膜瓣上及巩膜瓣下放置０．３～０．４ｍｇ／ｍｌＭＭＣ４～５分钟，术后前房出血的发生率进行了比较。结果：未应用ＭＭＣ组前房出血的发生率为４．１７％，巩膜瓣上置ＭＭＣ组前房出血的发生率为６．０６％，巩膜瓣下置ＭＭＣ组前房出血的发生率为３７．８４％，明显高于前两组，Ｐ＜０．０１。结论：巩膜瓣下置ＭＭＣ组前房出血的发生率明显增高，可能是ＭＭＣ对睫状体血管内皮细胞损伤的结果。
Objective:To study the cause of hyphema after trabeculectomy with mitomycin C(MMC).Methods:Obsered the hyphema after trabeculectomy in 99 cases(142 eyes)of primary glaucoma and compared the propotion of hyphema with three groups:not applied MMC,applied to episclera and applied to scleral bed after scleral flap with 0 3～0 4mg/ml MMC during trabeculectomy for 4～5 minutes.Results:The proportion of hyphema in the group not applied MMC,applied to scleral and to scleral bed after scleral flap was 4 17%,6 06% and 37 84% separately.The proportion of hyphema in the group applied MMC to scleral bed was significantly higher than that of the other groups (P<0 01).Conclusion:Higher proportion of hyphema in the group applied MMC to scleral bed,possibly,is caused by injury of ciliary vascular endothelium.
