Abstract
BACKGROUND AND OBJECTIVE
To assess the role for intraoperative optical coherence tomography (iOCT) during subretinal perfluoro-n-octane (PFO) removal and evaluate it as an assistive technique during surgical maneuvers.
MATERIALS AND METHODS
DISCOVER is a prospective study examining microscope-integrated iOCT systems in ophthalmic surgery. The authors report a technique utilizing iOCT guidance and feedback for surgical removal of chronic subretinal PFO.
RESULTS
In this technique, real-time iOCT feedback successfully guided surgical maneuvers to facilitate removal of PFO. Due to the chronicity of the PFO, it was loculated and resistant to multiple maneuvers. Utilizing real-time feedback, additional maneuvers were attempted with feedback to the surgeon regarding the success of removal. Postoperatively, visual acuity improved with anatomic normalization.
CONCLUSION
Microscope-integrated iOCT with real-time feedback provided important information to the surgeon that helped facilitate subretinal PFO removal and guided surgical maneuvers.
摘要
背景与目的
评估术中光学相干断层扫描（iOCT）在视网膜下全氟正辛烷（PFO）清除术中的作用，并将其作为手术操作中的辅助技术进行评估。
材料与方法
DISCOVER是一项在眼科手术中研究显微镜集成iOCT系统的前瞻性研究。作者报告了一种利用iOCT引导和反馈进行慢性视网膜下PFO手术清除的技术。
结果
在该技术中，实时iOCT反馈成功引导手术操作，以促进PFO的清除。由于PFO的慢性化，它被包裹且对多种操作有抵抗性。利用实时反馈，尝试了额外的操作，并向外科医生反馈清除的成功情况。术后，视力随着解剖结构的正常化而提高。
结论
具有实时反馈的显微镜集成iOCT为外科医生提供了重要信息，有助于促进视网膜下PFO的清除并指导手术操作。
