Argus II视网膜假体系统（Second Sight Medical Products，Sylmar，CA）目前已获批用于视网膜色素变性患者的植入。虽然接近的电极到视网膜表面的设备的最佳功能是至关重要的，单独的操作显微镜不允许可视化的电极从视网膜surfaces.We的距离演示增强可视化的电极到视网膜的距离使用显微镜集成OCT（MIOCT）获得的图像。由于6.7%的器械在临床试验中需要重新定位，外科医生报告称，使用MIOCT在横截面（二维）中可视化电极阵列，以验证正确的定位和术中位置。1、2使用超快扫频源MIOCT的实时体积（4维）术中成像允许外科医生实时反馈，以验证术中理想的植入位置。
The Argus II Retinal Prosthesis System (Second Sight Medical Products, Sylmar, CA) is currently approved for implantation in patients with retinitis pigmentosa. Although the proximity of the electrodes to the retina surface is crucial for optimal functioning of the device, the operating microscope alone does not allow for visualization of the distance of the electrodes from the retinal surface.We demonstrate the enhanced visualization of the electrode to retina distance using images obtained with microscope-integrated OCT (MIOCT). Because 6.7% of devices required retacking in clinical trials, surgeons have reported visualizing the electrode array in crosssection (2-dimensional) with MIOCT to verify proper tacking and intraoperative position. 1, 2 Live volumetric (4-dimensional) intraoperative imaging using ultrafast swept-source MIOCT allows for real-time surgeon feedback to verify the ideal implantation position intraoperatively.
