透明质酸钠在青光眼小梁切除术中的应用

目的探讨青光眼小梁切除术结束时向前房内注入透明质酸钠，预防术后浅前房发生的临床效果。方法观察组64例（76只眼）原发性闭角型青光眼，在小梁切除手术结束时，向前房内注入透明质酸钠形成正常前房，对照组64例（74只眼），在手术结束时向前房内注入平衡盐液。结果观察组术后浅前房12眼，占15．8％，对照组术后浅前房34眼，占45．9％，统计学处理两者差异有显著性（P〈0．05）两组术后眼压被控制在正常范围情况比较，差异无统计学意义（P〉0．05）。结论青光眼小梁切除术结束时向前房内注入透明质酸钠，可预防术后浅前房发生，减少术后并发症，提高手术安全性，并且眼压控制效果与前房内未注入透明质酸钠相近。

ApplicatiOn of sodium hyaluronate for trabeculectomy

Objective To study the effect of sodium hyaluronate （NAHA） on intraocular pressure and occurrence of shallow anterior chamber by injecting after primary angle closer glaucoma trabeculectomy. Methods In the experimental group （64 cases, 76 eyes） of primary glaucoma, NAHA was injected into anterior chamber to form normal anterior chamber at the end of trabeculectomy, and in control group （64 cases, 74 eyes） of primary angle closure glaucoma, NAHA was not injected into anterior chamber at the end of trabcculectomy. Results In the experimental group, there were 12 eyes （15.8%） of shallow anterior chamber after trabeculectomy, while in control group, 34 eyes （45.9%） of shallow anterior chamber occurred （P〈0.05）. There was no significant difference in the controlled normal range of intraocalar pressure （P〉0. 05）. Conclusion At the end of glaucoma trabeeuleetomy, injection of NAHA into anterior chamber can prevent shallow anterior chamber, decrease post operation complication, and increase the safety of the operation.
