Abstract:
Objective To investigate the primary angle-closure glaucoma iris weeks after cutting holes cut the width of the near future, long-term effect relationship, selected after close to long-term efficacy of the forecasting methods to improve iridectomy success rate. Methods 90 cases (116 eyes) with primary angle-closure glaucoma were randomly divided into three groups:A group(the width of the iris-week cut-hole cut 1.5mm) ,30 cases 42 eyes;B group(removal of the width of the iris weeks Ceccon 2 mm) ,30 cases 40 eyes;C group(the width of the iris-week cut-lole cut 3 mm) ,30 cases 34 eyes,after over 1 month,they were followed up to observe the intraocular pressure,anterior chamber angle width of the depth, depending on the features, the iris in recent weeks, as well as cutting holes,long-term concurrency disease. Results A:recent surgery success rate of 85.79% ,long-term surgical success rate of 76. 19% ;B group of recent surgery success rate of 87.5% ,long-term surgical success rate of 82.5% ;C group of recent surgery success rate of94.11% ,long-term surgical the success rate of 88.23%, X2 test the difference was significant(P＜ 0. 05) ;3 postoperative IOP decreased in varying degrees compared with the preoperative differences were significant(P＜0.01) ;peripheral angle after deep Random mean :A group of ≥ 1/3CT,compared the difference between before and after surgery were significantly( P ＜ 0.01 ) ;B group and C group ＞ 1/2CT,2 groups were compared before and after surgery the difference was highly significant( P ＜ 0.05 ). Conclusion Iridectomy was the treatment of primary angle-closure glaucoma safe and effective method of cutting holes. The width of the iris weeks to 2～3 mmwas appropriate, beneficial to control the iris weeks before the adhesion and angle-cut hole shallow narrowing.
