前房穿刺在高眼压下青光眼滤过手术中应用

目的探讨前房穿刺在高眼压下行青光眼滤过手术中的应用对手术疗效和手术并发症的影响。方法对22例（22只眼）急性闭角型青光眼联合应用药物降眼压48h后眼压仍﹥50mmHg,急诊行滤过手术,在做小梁切除前先行前房穿刺缓慢放出前房水,术后随访3～24月。结果22例22只眼眼压从术前平均（52.56±6.51）mmHg下降为术后平均（14.28±5.16）mmHg,手术成功率为90.91%。主要并发症为术后浅前房。结论前房穿刺是在高眼压下进行青光眼滤过手术的安全有效措施。

Application of anterior chamber paracentesis in filtrating operation for glaucoma under ocular hypertension

Objective To investigate the effect of anterior chamber paracentesis in trabeculectomy for the patients with glaucoma under ocular hypertension and complications. Methods 22 patients（22 eyes） whose intraocular pressure were greater than 50mmHg after anti-glaucoma medication of combination over 48 hours were performed anterior chamber paracentesis before trabeculectmy and followed up for 3-24 months. Results The IOP of 22 eyes were decreased from pre-operation 52.56 ± 6.51mmHg to post-operation 14.28±5.16mmHg. The success rate of operation was 90.91%. The shallow of anterior chamber was main complication. Conclusion Anterior chamber paracentesis is a effective and safe measure during trabeculectomy under ocular hypertension with less complication and high successful rate.
