青光眼复合小梁切除手术后浅前房的特点

The characteristics of shallow anterior chamber after complex trabeculectomy combining

目的：探讨术中用丝裂霉素和可松解缝线的青光眼复合小梁切除手术（M—RS—T）后浅前房的特点并探讨其可松解缝线的安全拆线时间。方法：将我院近7年M—RS—T术后连续性的浅前房患者31例31眼，除了6例在观察期间发生III度浅前房外，其它患者避免了散瞳状态造成的前房变化，浅前房I、II浅（IIs）、II深（IId）、111分别计分为1、2、3、4，统计观察两组术后每天的浅前房恢复的眼数和浅前房总分数。结果：在M—RS—T手术后第3天浅前房总分数达到最高水平，并持续到第7天才开始下降，到第8天直线下降；第7前房恢复4眼，第8天共恢复25眼（80．65％）。结论：M--RS--T手术后浅前房一般持续时间为8天，提示M—RS—T的可松解缝线尽可能在手术后8天以后拆线较安全，浅前房在第3天表现最严重。

Objective To study the characteristics of shallow anterior chamber after complex trabeculectomy combining with mitomycin C and releasable sutures （M--RS--T）, and explore the save time to remove the releasable sutures. Methods There were 31 eyes of 31 consecutive glaucoma patients who had shallow anterior chamber after M--RS--T at our hospital during recent 7 years. All the patients had avoided mydriasis condition which might change the degrees of shallow anterior chamber, except 6 patients who had III degree shallow anterior chamber the observed time. Shallow anterior chamber I, IIs, IId and III had been given 1,2,3 and 4 scores respectively. The total scores had been summed and the recovered eyes been recorded every days after operation. Results The total scores of shallow anterior chamber reached the highest level 3 days after M--RS--T and continued to the 7th day, and start to decrease slightly, and straight to fall down to the 8th day. There were 4 eyes recovered on the 7th day and 25 eyes totally （80.65%） recovered on the 8th day after M--RS--T. Conclusion The continued duration of shallow anterior chamber is generally 8 days after M--RS--T. It is implied that the releasable sutures of M--RS--T be removed 8 days later after operation as possible. Shallow anterior chamber reached the worst 3 days after M--RS--T.
