改良Ahmed引流阀治疗外伤性青光眼的疗效

目的 评价改良的FP-7Ahmed青光眼引流阀植入术治疗外伤性青光眼的临床疗效。方法 回顾性病例系列研究。收集2014年8月至2016年2月住院行改良的FP-7Ahmed青光眼引流阀植入术治疗的32例 (32只眼) 外伤后继发性青光眼患者临床资料, 分析患者病因、手术前后最佳矫正视力、眼压, 术后早期并发症及手术成功率。结果 引起患者眼压升高的原因多样, 存在多种因素的联合作用。患者术后最佳矫正视力不同程度提高者10眼, 无改变者15眼, 下降者为7眼;患者术前平均眼压为 (38.8±9.2) mm Hg;术后1、3、6、12、24个月眼压分别为 (13.2±4.5) mm Hg、 (15.7±4.8) mm Hg、 (16.2±5.2) mm Hg; (17.7±6.7) mm Hg及 (18.6±7.8) mm Hg, 与术前比较, 术后不同时间点眼压均明显下降, 差异均有统计学意义 (t=14.14、12.59、12.10、10.26、9.29, P <0.05) 。改良的FP-7Ahmed引流阀植入术后1、3、6、12、24个月的总成功率分别为100%、93.75%、90.63%、86.05%、76.67%。结论 改良的青光眼引流阀植入术治疗外伤后继发性青光眼安全有效, 注意手术技巧, 可减少术后部分并发症的发生。

Effect of Improved Ahmed Glaucoma Valve Implantation for Treating Traumatic Secondary Glaucoma

Objective To evaluate the clinical curative effect of improved FP-7 Ahmed glaucoma valve (AGV) implantation for treating traumatic secondary glaucoma. Methods We used retrospective case series study.We collected a total of 32 eyes of 32 patients with traumatic secondary glaucoma patients who underwent improved FP-7 Ahmed glaucoma valve implantation, the change of intraocular pressure (IOP) , the best corrected visual acuity (BCVA) , success rate and early postoperative complications were observed 24 months after surgery. Results There were many factors causing the traumatic secondary glaucoma, and there were many combined factors. Compared to preoperation, the BCVA was improved in 10 eyes, remained the same in 15 eyes, and decreased in 7 eyes. IOP was significantly decreased after surgery with improved FP-7 AGV implantation (P<0.05) , (38.8 ± 9.2) mm Hg before surgery vs (13.2±4.5) mm Hg, (15.7±4.8) mm Hg, (16.2±5.2) mm Hg, (17.7±6.7) mm Hg and (18.6±7.8) mm Hg at the 1, 3, 6, 12, 24 months after surgery. The total success rate of AGV implantation at the 1, 3, 6, 12, 24 months after surgery was 100%, 93.75%, 90.63%, 86.05%, 76.67%. Conclusion Improved FP-7 AGV implantation is safe and effective, to improve surgeons' operative technique may reduce the complications
