Ahmed FP-7眼压阀植入治疗难治性青光眼临床观察

摘要

Objective To observe clinical efficacy of Ahmed glaucoma valve implantation to treat refractory glau-coma. Methods This is a retrospective study. Author observed 64 patients (64 eyes)who underwent Ahmed FP-7 glauco-ma valve implantation surgeries. Intraocular pressure (IOP),visual acuity and complications were followed at 1 week,1 month,3 months,6 months and 1 year after surgery. A successful treatment is defined as that the patient can perceive the light,intraocular pressure between 5 and 21 mm Hg,and the patient needs no further glaucoma surgery. Results The av-erage IOP is 17. 89 ± 5. 85 mm Hg after surgery,significantly better than that before treatment (37. 7 ± 17. 7 mm Hg). Complications included low IOP and choroidal detachment in early stages and high IOP,exposed valve,and cicatrization in late stages. Conclusion Ahmed FP-7 glaucoma valve is a good choice to treat refractory glaucoma. However,the surgery should be operated carefully and complications should be expected and managed.%目的观察Ahmed FP-7眼压阀植入治疗难治性青光眼的临床疗效。方法回顾性自身前后对照研究，纳入难治性青光眼患者64例（64只眼），并进行Ahmed FP-7眼压阀植入术。通过观察术前、术后1周、术后1个月、术后3个月、术后6个月、术后1年患者的眼压、视力、并发症等情况。眼压控制成功标准为眼压＞5 mmHg和＜21 mmHg，无需再行抗青光眼手术、无光感丧失。结果难治性青光眼患者64例（64只眼），在术后1年平均眼压为（17．87±5．85）mmHg，与术前眼压（37．7＋17．7）mmHg比较，统计学有明显差异。患者术后3个月、6个月、1年时成功率为92．2％、87．5％、87．5％。术后并发症有：术后早期发生低眼压、脉络膜脱离等，晚期可见眼压控制不良、眼压阀暴露、瘢痕包裹等。结论 hmed FP-7眼压阀植入术是治疗难治性青光眼的较好选择，但需注意术中操作和术后并发症处理。
