目的 :探讨小梁切开术联合小范围小梁切除术治疗先天性青光眼的有效性和安全性。方法 :对 14例 ( 2 0只眼 )先天性青光眼行小梁切开术联合小范围小梁切除术。术后观察眼压、角膜横径、杯盘比值、滤过泡及并发症。随访 2 4～ 3 6个月平均 2 6 2 0± 6 0 2个月。结果 :术前平均眼压 3 2 5 0± 7 3 2mmHg ,最后一次随访时的平均眼压 14 60± 4 3 2mmHg ,两者差异有显著性 (t =6 2 4,P <0 0 1) ,手术成功率为 95 % (IOP <2 1mmHg)。术后 15只眼有功能性滤过泡。所有病例角膜横径和杯盘比值稳定。无玻璃体脱出 ,浅前房 ,虹膜粘连及眼内感染等并发症。结论 :小梁切开术联合小范围小梁切除术是一种安全、有效的治疗先天性青光眼的方法。
Objective: To investigate the effectiveness and safety of trabeculectomy and trabeculectomy in the treatment of congenital glaucoma. Methods: 14 cases (20 eyes) of congenital glaucoma trabeculectomy combined with a small trabeculectomy. Postoperative intraocular pressure, corneal diameter, cup ratio, filtration bleb and complications. The follow-up ranged from 24 to 36 months, with an average of 2620 ± 6 0 2 months. Results: The preoperative average intraocular pressure was 3250 ± 732mmHg, and the mean intraocular pressure at the last follow - up was 1460 ± 432.2mmHg, the difference was significant (t = 624, P <0.01) , The success rate of surgery was 95% (IOP <2 1mmHg). Fifteen eyes had functional filtration bleb after operation. All cases of corneal diameter and cup ratio stable. No vitreous prolapse, shallow anterior chamber, iris adhesions and intraocular infections and other complications. Conclusion: Trabeculectomy combined with small-scale trabeculectomy is a safe and effective method for the treatment of congenital glaucoma.
