Abstract：
OBJECTIVE: To present the short-term outcomes of our novel technique, the suture-assisted method, in long scleral tunnel Ahmed Glaucoma Valve (AGV) implantation.
METHODS: This retrospective study included glaucoma patients who underwent AGV implantation using the suture-assisted long scleral tunnel method and were fellowed for at least 6 months between January 2022 and November 2022. Preoperative and postoperative assessments included best-corrected visual acuity (BCVA), intraocular pressure (IOP), anterior and posterior segment examinations, anti-glaucomatous medications, and intraoperative and postoperative complications were also evaluated.
RESULTS: Eight eyes of seven patients were included in the study. The mean age was 52.25 ± 29.38 years (r:8-76 years), and there were 5 female and 2 male patients. The mean follow-up duration period was 8.62 ± 2.50 months (r:6-12 months). The mean IOP was 27.12 ± 3.48 mmHg preoperatively and 11.62 ± 3.48 mmHg on postoperative on 1st day, 11.62 ± 3.20 mmHg at 1st week, 18.75 ± 8.94 mmHg at 1st month, 16.62 ± 2.72 mmHg at 3rd month, 16.12 ± 3.75 mmHg at 6th month. Postoperative hyphema was observed in one eye, and tenon cyst excision was performed in two eyes. No tube exposure was observed in any eye during the follow-up period. No hypotony-related complications were observed during follow-up.
CONCLUSIONS: We believe that suture-asissted application of the long scleral tunnel method not only prevents tube exposure but also facilitates the passage of the AGV silicone tube through the scleral tunnel, reducing the surgical time contributing to a decreased the risk of infection.

摘要：
目的：为了展示我们新技术的短期结果，缝合辅助方法，在长巩膜隧道Ahmed青光眼瓣膜（AGV）植入。
方法：这项回顾性研究纳入了青光眼患者，这些患者在2022年1月至2022年11月期间接受了缝线辅助长巩膜隧道法的AGV植入术，至少6个月。术前和术后评估包括最佳矫正视力（BCVA），眼内压（IOP），前段和后段检查，抗青光眼药物，术中和术后并发症也进行了评估。
结果：7名患者的8只眼睛被纳入研究。平均年龄为52.25±29.38岁（r：8-76岁），女性5例，男性2例。平均随访时间为8.62±2.50个月(r:6~12个月)。术前平均IOP为27.12±3.48mmHg，术后第1天平均IOP为11.62±3.48mmHg，第1周11.62±3.20mmHg，第1个月18.75±8.94mmHg，第3个月16.62±2.72mmHg,第6个月时16.12±3.75mmHg。术后观察到一只眼的前房积血，两只眼睛进行了肌腱囊肿切除术。在随访期间，任何眼睛均未观察到管暴露。随访期间未观察到低张力相关并发症。
结论：我们认为，长巩膜隧道法的缝合应用不仅可以防止管暴露，而且可以促进AGV硅胶管通过巩膜隧道，减少手术时间有助于降低感染风险。
