巩膜瓣下Ex-press引流器植入治疗外伤性青光眼的临床疗效

目的：观察巩膜瓣下 Ex-press 青光眼引流器植入治疗外伤性青光眼的临床疗效。
　　方法：对2012-12/2013-05我院眼科19例19眼外伤性青光眼患者施行巩膜瓣下 Ex-press 青光眼引流器植入手术,观察记录术后视力、前房、眼压、滤过泡及其它并发症的情况。
　　结果：Ex-press 青光眼引流器均成功植入。术后第1d 有2眼发生暂时性浅前房,3眼少量前房出血。术后3mo 矫正视力提高9眼(47%),18眼(95%)为功能性滤过泡,平均眼压为12.1依6.1mmHg。术后6mo 矫正视力提高11眼(58%),18眼(95%)为功能性滤过泡,平均眼压为13.3依6.9mmHg。与术前平均眼压(29.8依6.7mmHg)比较,差异有统计学意义(P<0.05)。
　　结论：巩膜瓣下 Ex-press 青光眼引流器植入治疗外伤性青光眼,术后视力改善、目标眼压稳定,并发症少,安全性高。

Clinical effect of Ex-press glaucoma filtration device implantation under scleral flap for traumatic glaucoma

AIM: To observe the clinical effect of Ex-press glaucoma filtration device implantation under scleral flap for traumatic glaucoma.

METHODS: Totally 19 eyes of 19 patients with traumatic glaucoma were implanted with Ex-press glaucoma filtration device under the scleral flap from December 2012 to May 2013. The postoperative visual acuity, anterior chamber depth and hyphema,intraocular pressure(IOP), filtering bleb and other complications were observed and summarized.

RESULTS: Ex-press glaucoma filtration device were implanted successfully in 19 patients. At 1d postoperatively shallow anterior chamber was occurred in 2 eyes and hyphema was occurred in 3 eyes. At 3mo postoperatively increased vision was occurred in 9 eyes(47%),functional filtering bleb was occurred in 18 eyes(95%),and IOP was 12.1±6.1mmHg. At 6mo postoperatively increased vision was occurred in 11 eyes(58%),functional filtering bleb was occurred in 18 eyes(95%),and IOP was 13.3±6.9mmHg.Compared with the preoperative IOP(29.8±6.7mmHg),the difference was significant(P<0.05).

CONCLUSION: Ex-press glaucoma filtration device implantationfor traumatic glaucoma can improve the postoperative vision and control the postoperative IOP stably with fewer complications and high safety.
