小梁切除术联合白内障超声乳化吸除术治疗原发性闭角型青光眼并白内障的疗效观察

目的 探讨小梁切除术联合白内障超声乳化吸除术治疗原发性闭角型青光眼并白内障的临床疗效.方法 对56例(56眼)原发性闭角型青光眼合并白内障患者采用晶状体超声乳化吸除联合小梁切除术治疗,观察术前术后视力、眼压、前房角及前房深度、滤过泡及并发症情况.结果 56例(56眼)术前视力:＜0.01者26例、0.1 ～0.2者23例、0.3 ～0.5者6例、＞0.05者1例,术后6个月视力分别为:4例、11例、21例、18例,手术前后视力改善情况差异有统计学意义(Z=-5.074,P＜0.05).术后6个月眼压为(15.26±3.37)mmHg,明显低于术前眼压(34.60±3.85)mm Hg,(t=28.29,P＜0.05).术后6个月前房深度为(3.27±0.64)mm,明显大于术前前房深度(1.58±0.39) mm(t=16.90,P＜0.05).所有患者均有滤过泡形成,无严重并发症.结论 小梁切除术联合白内障超声乳化吸除术可有效地治疗闭角型青光眼合并白内障.

Clinical efficacy of lens trabeculectomy combined with phacoemulsification in the treatment of angle-closure glaucoma with cataract

Objective To explore the clinical efficacy of trabeculectomy combined with phacoemulsification in the treatment of angle-closure glaucoma with cataract. Methods 56 cases of angle-closure glaucoma with cataract were selected in department of ophthalmology and were received trabeculectomy combined with phacoemulsification. Preoperative and postoperative visual acuity, intraocular pressure, anterior chamber angle, anterior chamber depth, filtering bleb and complications were observed. Results Six months after operation,53 （94.64%） were improved in visual acuity. There was significant difference between preoperative and postoperative visual acuity （Z = -5. 074, P 〈 0.05 ）. lOP was（ 15.26 ± 3.37 ） mm Hg 6 months after operation ,which was significant lower than（ 34.60 ± 3.85 ） mm Hg before operation （ t = 28.29, P 〈 0.05 ）. The anterior chamber depth was （ 3.27 ± 0. 64 ） mm 6 months after operation, which was significant larger than （1.58 ± 0. 39 ）mm before operation（ t = 16.90, P 〈 0. 05 ）. All patients had bleb formation with no serious complications. Conclusion Trabeculectomy combined with phacoemulsification was effective in treating angle-closure glaucoma and cataract.
