Argus II视网膜假体系统的最佳放置至关重要。术中OCT允许术中可视化和确认阵列放置。在本研究中,评价了两种不同的OCT系统,以评估该技术在Argus II手术中的可行性和实用性。2015年6月至2016年7月,在科尔眼科研究所对5名接受Argus II植入术的患者进行了术中OCT。使用EnVisu便携式OCT(Bioptigen,Research Triangle Park)和显微镜集成的RESCAN 700(Zeiss,上科亨,德国)术中OCT系统。3名患者使用了EnVisu,5名患者中有3名使用了RESCAN 700。阵列固定后,对整个阵列(包括边缘和固定钉)进行术中OCT。术中OCT允许阵列/视网膜界面的可视化。OCT系统的显微镜集成便于聚焦、实时反馈、外科医生指导的OCT扫描到感兴趣区域,并提高了感兴趣点的图像质量。Argus II电极阵列的术中成像是可行的,并提供有关电极阵列-视网膜界面和距离的信息,以帮助指导外科医生。OCT的显微镜集成似乎为Argus II阵列放置期间的术中OCT提供了最佳和有效的方法。
Optimal placement of the Argus II Retinal Prosthesis System is critical. Intraoperative OCT allows for intrasurgical visualization and confirmation of array placement. In this study, two different OCT systems were evaluated to assess the feasibility and utility of this technology during Argus II surgery. Intraoperative OCT was performed on five patients undergoing Argus II implantation at Cole Eye Institute from June 2015 to July 2016. The EnVisu portable OCT (Bioptigen, Research Triangle Park) and microscope-integrated RESCAN 700 (Zeiss, Oberkochen, Germany) intraoperative OCT systems were utilized. The EnVisu was used in three patients and the RESCAN 700 in three of the five patients. Following array tacking, intraoperative OCT was performed over the entire array including the edges and tack. Intraoperative OCT allowed for visualization of the array/retina interface. Microscope integration of the OCT system facilitated ease of focusing, real-time feedback, surgeon-directed OCT scanning to the areas of interest, and enhanced image quality at points of interest. Intraoperative imaging of the Argus II electrode array is feasible and provides information about electrode array-retina interface and distance to help guide a surgeon. Microscope-integration of OCT appears to provide an optimal and efficient approach to intraoperative OCT during Argus II array placement.
