To validate the performance of the Notal OCT Analyzer (NOA) in processing self-administered OCT images from an OCT system designed for home use (home OCT [HOCT]) as part of a pivotal study aimed at achieving de novo United States Food and Drug Admininstration marketing authorization.
A prospective quantitative cross-sectional artificial intelligence study.
The study enrolled adults aged ≥55 years diagnosed with neovascular age-related macular degeneration (nAMD) in ≥1 eligible eye with a best-corrected visual acuity of 20/320 or better.
Participants self-imaged 4 times on each of 2 HOCT devices and once with an in-office OCT (IO-OCT) device during a single visit. Scans were segmented by the NOA and human graders at a certified reading center (RC).
Intradevice and interdevice repeatability and reproducibility of total retinal hyporeflective (TRO) volume estimation by the NOA on HOCT-acquired images as compared with that of RC graders on IO-OCT-acquired images. Additionally, to assess the performance of the NOA in segmentation of TRO over multiple B-scans as compared with RC graders.
Self-imaging was performed successfully by 387 participants in 2451 of 2616 attempts (93.7%). For repeatability, the coefficient of variance for NOA was 11.1% for eyes with >10 volume units of TRO imaged with HOCT compared with 16.4% for RC graders segmenting IO-OCT images. The median DICE similarity coefficients for segmentation of TRO by NOA vs. Grader 1, Grader 2, and Grader 3; Grader 1 vs. Grader 2 and Grader 3; and Grader 2 vs. Grader 3 were 0.68, 0.68, 0.61, 0.72, 0.63, 0.70, respectively.
The performance of NOA supports the intended use of the system as a tool to monitor TRO at home between routine clinical visits in support of the management of nAMD.

作为一项旨在获得美国食品药品监督管理局(FDA)全新上市许可的关键研究的一部分,验证Notal OCT分析仪(NOA)处理来自家用OCT系统(家用OCT [HOCT])的自我管理OCT图像的性能。
一项前瞻性定量横断面人工智能研究。
该研究纳入了年龄≥55岁、至少一只符合条件的眼睛被诊断为新生血管性年龄相关性黄斑变性(nAMD)且最佳矫正视力为20/320或更好的成年人。
参与者在单次就诊期间,在两台HOCT设备上各自行4次自我成像,并使用办公室内OCT(IO - OCT)设备进行1次成像。扫描图像由NOA和认证阅读中心(RC)的人工分级人员进行分割。
与RC分级人员对IO - OCT获取图像的分级相比,NOA对HOCT获取图像的总视网膜低反射(TRO)体积估计的设备内和设备间重复性及再现性。此外,评估与RC分级人员相比,NOA在多个B扫描上对TRO的分割性能。
387名参与者在2616次尝试中的2451次(93.7%)成功完成自我成像。对于重复性,HOCT成像的TRO体积大于10体积单位的眼睛,NOA的变异系数为11.1%,而RC分级人员对IO - OCT图像进行分割的变异系数为16.4%。NOA与分级人员1、分级人员2和分级人员3对TRO分割的中位DICE相似系数;分级人员1与分级人员2和分级人员3;以及分级人员2与分级人员3分别为0.68、0.68、0.61、0.72、0.63、0.70。
NOA的性能支持该系统作为一种工具的预期用途,即在常规临床就诊之间在家中监测TRO,以辅助nAMD的管理。
