PURPOSE
To evaluate the clinical efficacy and safety of the double-plate Ahmed Glaucoma Valve.
DESIGN
Multicenter, retrospective observational case series.
METHODS
We reviewed 50 eyes in 50 patients treated with the double-plate Ahmed Glaucoma Valve with mean follow-up of 11.7+/-7.9 months.
RESULTS
Average intraocular pressure was reduced from 36.0+/-12.4 mm Hg before surgery to 15.8+/-7.7 mm Hg at the most recent follow-up after surgery (P<.001). The number of glaucoma medications was decreased from 3.3+/-0.8 before surgery to 1.4+/-1.4 after surgery (P<.001). The percent of success was 76% of eyes at the latest follow-up. Choroidal effusion occurred in four eyes (8%) and did not require surgical treatment in any eye.
CONCLUSIONS
Despite a poor prognosis group of patients in this study, the double-plate Ahmed Glaucoma Valve was effective in lowering intraocular pressure with a low incidence of complications associated with hypotony.
目的
评估双盘Ahmed青光眼引流阀的临床疗效和安全性。
设计
多中心回顾性观察病例系列。
方法
我们回顾了50例接受双盘Ahmed青光眼引流阀治疗的患者的50只眼睛，平均随访时间为11.7±7.9个月。
结果
平均眼压从手术前的36.0±12.4毫米汞柱降至手术后最近一次随访时的15.8±7.7毫米汞柱（P<0.001）。青光眼药物的使用数量从手术前的3.3±0.8种降至手术后的1.4±1.4种（P<0.001）。在最近一次随访时，成功率为76%。4只眼睛（8%）出现脉络膜积液，所有眼睛均无需手术治疗。
结论
尽管本研究中的患者预后较差，但双盘Ahmed青光眼引流阀在降低眼压方面有效，且与低眼压相关的并发症发生率较低。
