Abstract

Purpose

To evaluate the success rate and complications of the Ahmed FP7 valve implanted via Pars Plana in a group of vitrectomized patients with refractory glaucoma and anterior segment abnormalities from January 2018 to June 2023.

Methods

Quasi-experimental, prospective study. Eleven eyes with refractory glaucoma were included. Participants underwent a comprehensive ophthalmic examination, including assessment of intraocular pressure (IOP) reduction, visual acuity, characterization of glaucoma type, and number of antiglaucoma medications.

Results

The mean baseline IOP was 37.3 ± 11 mmHg, which decreased to 13.5 ± 3.0 mmHg after one year. The qualified success rate was 63.7%, while the complete success rate was 36.3%. The most common diagnosis was neovascular glaucoma in 36.4% of cases. The most frequent postoperative complications were choroidal detachment and hypotony.

Conclusions

Our data suggest that implantation of the Ahmed FP7 valve via pars plana is an effective and safe option for patients with refractory secondary glaucoma.

在难治性青光眼患者中实施 Ahmed® 瓣膜植入术的效果。

目的：评估 2018 年 1 月至 2023 年 6 月期间，在一组经玻璃体切除术治疗的难治性青光眼和眼前节异常患者中，经旁路植入 Ahmed FP7 瓣膜的成功率和并发症：准实验前瞻性研究。共纳入 11 名患有难治性青光眼的患者。参与者接受了全面的眼科检查，包括评估眼压降低情况、视力、青光眼类型特征以及抗青光眼药物的数量：平均基线眼压为 37.3 ± 11 mmHg，一年后降至 13.5 ± 3.0 mmHg。合格成功率为 63.7%，完全成功率为 36.3%。最常见的诊断是新生血管性青光眼，占 36.4%。最常见的术后并发症是脉络膜脱离和眼压过低：我们的数据表明，对于难治性继发性青光眼患者来说，通过眼旁植入 Ahmed FP7 瓣膜是一种有效而安全的选择。
