Comparison of the conjunctiva related complication rates and success rates among eyes with Ahmed glaucoma valve (AGV) implantation in which eye bank derived scleral and corneal patch grafts had been used to cover the tube.
Retrospective comparative study. Patients who underwent AGV implantation between January 2000 to December 2016 were included. Demographic, clinical data, intra and post operative data was obtained from electronic medical records. Conjunctiva related complications were divided into two groups: with and without implant exposure. Conjunctiva related complication rates, success rate, risk factors among eyes with corneal and scleral patch graft were compared.
Three hundred and twenty three eyes of 316 patients underwent AGV implantation. Scleral patch graft was used in 214 eyes of 210 patients (65.9%) and corneal patch graft was used in 109 eyes of 107 patients (34%). Median follow up was 14 months. There was no significant difference in the conjunctiva related complication rate (7.3 % in corneal patch graft versus 7.0% in scleral patch graft;p=0.5) and conjunctival dehiscence rate (3.7% versus 4.6%, P = 0.7) among the two groups. Success rate was significantly higher in the corneal patch graft group versus the scleral patch graft group (98% versus 72%; p=0.001). Eyes with corneal patch graft had a higher survival rate (P = 0.01).
There was no significant difference in the rate of conjunctiva related complications following corneal and scleral patch grafts used to cover the AGV tube. Eyes with corneal patch graft had a higher success rate and survival rate.
比较使用眼库供体巩膜和角膜贴片移植物覆盖引流管的 Ahmed 青光眼阀（AGV）植入术后结膜相关并发症发生率和成功率。
回顾性比较研究。纳入 2000 年 1 月至 2016 年 12 月期间接受 AGV 植入术的患者。从电子病历中获取人口统计学、临床数据、术中及术后数据。将结膜相关并发症分为两组：有和无植入物暴露。比较角膜和巩膜贴片移植术后结膜相关并发症发生率、成功率及危险因素。
316 例患者的 323 只眼接受了 AGV 植入术。210 例患者的 214 只眼（65.9%）使用了巩膜贴片移植物，107 例患者的 109 只眼（34%）使用了角膜贴片移植物。中位随访时间为 14 个月。两组间结膜相关并发症发生率（角膜贴片移植物为 7.3%，巩膜贴片移植物为 7.0%；p=0.5）和结膜裂开率（3.7%对 4.6%，P=0.7）无显著差异。角膜贴片移植物组的成功率明显高于巩膜贴片移植物组（98%对 72%；p=0.001）。角膜贴片移植物眼的存活率更高（P=0.01）。
使用巩膜和角膜贴片移植物覆盖 AGV 管后，结膜相关并发症的发生率无显著差异。使用角膜贴片移植物的眼成功率和存活率更高。
