保持前房状态下小梁切除术的临床观察

目的　探讨保持前房状态下小梁切除术的效果。方法　 77例 ( 88眼 )原发性闭角型青光眼分为两组 :透明质酸钠组 3 2例 ( 4 1眼 )行前房注入透明质酸钠后再行常规小梁切除术 ;对照组 45例 ( 4 7眼 )行常规小梁切除术。结果　浅前房发生率透明质酸钠组 12 2 0 % ( 5 /4 1) ,对照组 3 1 91% ( 15 /4 7) ,两组比较P <0 .0 5 ,差异有显著性意义。手术成功率透明质酸钠97 5 6% ( 4 0 /11) ,对照组 89 3 6% ( 4 2 /4 7) ,两组比较P >0 .0 5 ,差异无显著意义。结论　保持前房状态下小梁切除术可降低浅前房发生率。

Clinical observation of trabeculectomy under the keeping of anterior chamber

Objective To explore the effect of trabeculectomy under the keeping of anterior chamber.Methods 77 eyes(77 patients) with primary angle-closure glaucoma were divided into two groups:41 eyes(32 patients) treated by normal trabeculectomy after being infused sodium hyaluronate into anterior chamber,47 eyes (45 patients) underwent normal trabeculectomy were used as control.Results The percentage of shallow anterior chamber was 12.20%(4/41) in the group with sodium hyaluronate and 31.91%(15/47) in normal trabeculectomy.There was significant difference between two groups( P<0.05) .The successful rate of operation was 97.56%(40/41) in the group with sodium hyaluronate and 89.36%(42/47) in the group of normal trabeculectomy respectively,no significant difference between two groups( P> 0.05) . Conclusion Trabeculectomy under keeping anterior chamber may decrease the occurrence of postoperative shallow anterior chamber.
