将使用广角眼底照相机（Canon CF-60 Z）及其内置495 nm波长的蓝色干涉滤光片（SE-40）拍摄的视网膜神经纤维层（RNFL）照片与使用相同照相机和无红色吸收滤光片（Wratten No. 58）拍摄的照片以及使用30°眼底照相机和Wratten No. 58滤光片拍摄的照片进行比较。对比显示，使用佳能相机和SE-40滤镜的60°图像角度可以实现RNFL及其缺陷的最佳可视化。用较小的图像角度（30°）和较长波长的滤波器，再现质量劣化。
Retinal nerve fibre layer (RNFL) photographs taken with a wide‐angle fundus camera (Canon CF‐60Z) and its built‐in blue interference filter (SE‐40) of 495 nm wavelength were compared with pictures taken with the same camera and a red‐free absorption filter (Wratten No. 58) as well as with photographs taken with a 30° fundus camera and Wratten No. 58 filter. Comparison showed that the best visualisation of the RNFL and its defects was achieved with the 60° picture angle of the Canon camera and SE‐40 filter. With a smaller picture angle (30°) and a filter of longer wavelength quality of reproduction deteriorated.
