Abstract

Purpose: To evaluate the utility of intraoperative optical coherence tomography (OCT) in filtration surgery using PRESERFLO^® MicroShunt.

Study design: Single-center prospective observational study METHODS: Filtration surgery using the MicroShunt was performed on 14 patients (15 eyes) diagnosed with open-angle glaucoma at our institution. The insertion pathway was created using a knife under intraoperative OCT guidance, and the position of the MicroShunt was verified after insertion. In cases of inadequate positioning, a new insertion pathway was created. Furthermore, the correct position was confirmed postoperatively using anterior segment OCT.

Results: In all cases, the real-time observation or replay playback of intraoperative OCT allowed for the visualization of the positional relationship between the device and surrounding tissues. This provided valuable assistance in determining the adequacy of the insertion pathway. In certain cases, the knife or inserted MicroShunt was in contact with the cornea or iris, leading to a revision of the insertion pathway. Regardless of the case, at the end of each surgery confirmation was made that the inserted MicroShunt was fixed in the proper position in the anterior chamber. Postoperative anterior segment OCT also revealed its presence in a similar position.

Conclusion: Intraoperative OCT is a valuable tool for ensuring a more secure insertion in filtration surgery using MicroShunt.

目的：评估术中光学相干断层扫描（OCT）在使用 PRESERFLO® MicroShunt 进行滤过手术中的实用性：单中心前瞻性观察研究方法：本院对 14 名诊断为开角型青光眼的患者（15 只眼）进行了使用 MicroShunt 的滤过手术。在术中 OCT 引导下用刀创建插入路径，并在插入后确认 MicroShunt 的位置。如果定位不准确，则创建新的插入路径。此外，术后还使用前节 OCT 确认了正确的位置：结果：在所有病例中，通过术中实时观察或重放 OCT，都能看到装置与周围组织之间的位置关系。这为确定插入路径是否适当提供了宝贵的帮助。在某些病例中，手术刀或插入的 MicroShunt 接触到角膜或虹膜，因此需要修改插入路径。无论哪种情况，每次手术结束时都要确认插入的 MicroShunt 已固定在前房的适当位置。术后前段 OCT 也显示其位置相似：术中 OCT 是确保使用 MicroShunt 进行滤过手术时更安全插入的重要工具。

期刊介绍： The Japanese Journal of Ophthalmology (JJO) was inaugurated in 1957 as a quarterly journal published in English by the Ophthalmology Department of the University of Tokyo, with the aim of disseminating the achievements of Japanese ophthalmologists worldwide. JJO remains the only Japanese ophthalmology journal published in English. In 1997, the Japanese Ophthalmological Society assumed the responsibility for publishing the Japanese Journal of Ophthalmology as its official English-language publication. Currently the journal is published bimonthly and accepts papers from authors worldwide. JJO has become an international interdisciplinary forum for the publication of basic science and clinical research papers.
