Optical coherence tomography (OCT) and reflectance imaging are used in clinical practice to measure the thickness and transverse dimensions of retinal features. The recent trend towards increasing the field of view (FOV) of these devices has led to an increasing significance of the optical aberrations of both the human eye and the device. We report the design, manufacture and application of the first phantom eye that reproduces the off-axis optical characteristics of the human eye, and allows the performance assessment of wide-field ophthalmic devices. We base our design and manufacture on the wide-field schematic eye, [Navarro, R. J. Opt. Soc. Am. A, 1985, 2.] as an accurate proxy to the human eye and enable assessment of ophthalmic imaging performance for a external FOV. We used multi-material 3D-printed retinal targets to assess imaging performance of the following ophthalmic instruments: the Optos 200Tx, Heidelberg Spectralis, Zeiss FF4 fundus camera and Optos OCT SLO and use the phantom to provide an insight into some of the challenges of wide-field OCT.

宽视场幻眼在光学相干断层扫描和反射成像中的应用

光学相干断层扫描（OCT）和反射成像在临床实践中用于测量视网膜特征的厚度和横向尺寸。最近增加这些设备的视场 (FOV) 的趋势导致人眼和设备的光学像差变得越来越重要。我们报告了第一个幻眼的设计、制造和应用，它再现了人眼的离轴光学特性，并允许对宽视场眼科设备进行性能评估。我们的设计和制造基于宽视场示意图眼，[Navarro，RJ Opt。苏克。是。A, 1985, 2.] 作为人眼的准确代理，能够评估外部 FOV 的眼科成像性能。我们使用多材料 3D 打印视网膜目标来评估以下眼科仪器的成像性能：Optos 200Tx、Heidelberg Spectralis、Zeiss FF4 眼底相机和 Optos OCT SLO，并使用模型来深入了解宽范围眼科仪器的一些挑战。 - 场 OCT。
