The eyeWatch System (EWS) (Rheon Medical, Lausanne, Switzerland) was developed as a glaucoma drainage device (GDD) to precisely control intraocular pressure (IOP) and thus prevent the development of postoperative hypotension and its complications.
To report 1‑year outcomes from a single-center cohort undergoing EWS surgery.
Retrospective review of patients undergoing EWS surgery at the University Eye Hospital Bonn, Germany from May 2021 to September 2022.
A total of 5 eyes of the first 5 consecutive patients treated with the EWS were included in this study. The mean preoperative IOP was 34.6 mm Hg (23-45 mm Hg) which was reduced to 12.2 mm Hg (9-18 mm Hg) with a mean reduction of 60%. Local pressure-lowering therapy was reduced from 2.8 agents preoperatively (1-4) to 0.6 agents after 1 year. All patients achieved the target IOP of below 21 mm Hg including 4 patients without any medication. The complication rate was low. One patient had to undergo two surgical revisions as the IOP was elevated to over 30 mm Hg after surgery and tube exposure became apparent during the course of the follow-up so that a second donor patch was sutured on. The same patient had an elevated IOP >30 mm Hg after a cMRI examination, so that a reduction of IOP by adjusting the EWS using the eyeWatch pen (EWP) was performed. IOP adjustments with the eyeWatch pen (EWP) were performed in 4 of 5 patients in the first year after surgery; the mean IOP before adjustment was 21.33 mm Hg (15-37 mm Hg) which was reduced to a mean of 8.58 mm Hg (4-16 mm Hg).
The EWS effectively lowers IOP and the amount of necessary pressure-lowering therapy. With the EWP postoperative adjustments of IOP are possible without further invasive measures.
眼观系统（EWS）（瑞士洛桑的瑞昂医疗公司）作为一种青光眼引流装置（GDD）被研发出来，用于精确控制眼压（IOP），从而预防术后低血压及其并发症的发生。
报告接受EWS手术的单中心队列的1年随访结果。
对2021年5月至2022年9月在德国波恩大学眼科医院接受EWS手术的患者进行回顾性研究。
本研究纳入了最初连续接受EWS治疗的5例患者的5只眼睛。术前平均眼压为34.6 mmHg（23 - 45 mmHg），术后降至12.2 mmHg（9 - 18 mmHg），平均降低了60%。局部降压治疗从术前的2.8种药物（1 - 4种）减少到1年后的0.6种药物。所有患者均达到眼压低于21 mmHg的目标，其中4例患者无需任何药物治疗。并发症发生率较低。1例患者术后眼压升高至30 mmHg以上，随访过程中出现引流管外露，因此进行了二次手术修补。同一患者在磁共振成像（cMRI）检查后眼压>30 mmHg升高，因此使用眼观笔（EWP）调整EWS以降低眼压。术后第一年，5例患者中有4例使用眼观笔（EWP）进行了眼压调整；调整前平均眼压为21.33 mmHg（15 - 3
