吲哚菁绿色（ICG）荧光血管造影术已进一步完善，用于实验室和临床研究。在蔡司眼底照相机的当前修改中，除了非球面物镜透镜之外的所有透镜都被特别地涂覆以增加在800 nm左右的光谱区域中的光透射。300瓦碘化铟灯连续光源已取代传统的氙气闪光灯。该光源产生265 mw的视网膜辐照度，因此将视网膜曝光时间限制为11.9秒，但该时间足以记录染料通过脉络膜。胶片上眼底的空间分辨率从11.7微米提高到7.4微米。
Indocyanine green (ICG) fluorescence angiography has been further refined for use in both laboratory and clinical investigations. In the present modification of the Zeiss fundus camera all lenses except the aspherical objective lens have been specially antireflection coated to increase light transmission in the spectral region around 800 nm. A 300 watt indium iodide lamp continuous light source has replaced the conventional xenon flash lamp. This light source produces a retinal irradiance of 265 mw, and therefore restricts retinal exposure time to 11.9 seconds, but that time is more than adequate to record passage of dye through the choroid. Spatial resolution of the fundus on the film has been increased from 11.7 microns to 7.4 microns.
