改良型小梁切除术治疗持续性高眼压疗效分析

目的:探讨改良后的小梁切除术治疗急性闭角型青光眼持续性高眼压状态的疗效评估。方法:选取符合要求的住院患者105例,分为试验组和对照组。对试验组患者行改良型小梁切除术,对照组行常规小梁切除术。记录手术前后患者视力、眼压及前房变化情况,进行统计分析。结果:试验组69例患者中51例(73.9%)视力较术前提高;视力未见提高的10例(14.5%)。术后眼压控制平稳的有46例(66.7%);术后出现浅前房的11例(15.9%)。对照组36例患者中17例(47.2%)视力较术前提高;视力未见提高的12例(33.3%);术后眼压控制平稳的有21例(58.3%),4例(11.1%)出现眼压失控,需行二次手术;术后出现浅前房的20例(55.6%)。结论:改良后的小梁切除术治疗急性闭角型青光眼持续性高眼压状态的疗效是安全、有效的。

Analysis of therapeutics of improved trabeculectomy for persistent ocular hypertension

AIM: To investigate the therapeutical effect of an improved trabeculectomy on the persistent ocular hypertension of acute angle-closure glaucoma.

METHODS: Totally 105 standardized patients were divided into two groups: experimental group and control group. The patients in experimental group were operated with an improved trabeculectomy and patients in control group were operated with the routine trabeculectomy. Visual acuity, intraocular pressure and changes of anterior chamber were recorded at the preoperative and postoperative period. The data were collected to do some statistical analysis.

RESULTS: Totally 51(73.9%)patients' visual acuities were improved in experimental group; 10(14.5%)patients' visual acuities did not change; intraocular pressure of 46 eyes(66.7%)was steady and normal; the anterior chambers of 11 eyes(15.9%)became more shadow than before. In control group, there were 17 eyes(47.2%)whose visual acuities were improved; 12(33.3)patients' visual acuities did not change; intraocular pressure of 21 eyes(58.3%)was steady and normal; the intraocular pressure of 4 eyes(11.1%)cannot be controlled, and need to be operated again. The anterior chambers of 20 eyes(55.6%)became more shadow than before.

CONCLUSION:The treatment of an improved trabeculectomy on the persistent ocular hypertension of acute angle-closure glaucoma is safe and valid.
