The transmission characteristics of a new filter combination for fluorescein angiography were selected on the basis of in vivo measurements of the excitation and emission spectra of fluorescein dye during its transit in the fundus. This combination of filters was characterized by separation of 530 nm between the spectral ranges of transmission of the excitation and barrier filters. In the standard filter combinations this separation is at about 495 nm. Compared to the standard filters, the new filters enhanced the film exposure for all sites of the fundus, especially for the macular area and choroidal fluorescence. There was an improvement in demonstration of the choroidal vasculature, especially in the macular area, and better visibility of retinal detail in the macular area, but a slight decrease in contrast of the retinal vessels outside the macular region. Improved visibility of the fundus for the observer and reduction of scattering in the ocular media of older subjects improved the overall quality of angiograms made with the new filters.
一种用于荧光素血管造影的新型滤光片组合的传输特性，是根据荧光素染料在眼底传输过程中激发光谱和发射光谱的体内测量结果来选择的。这种滤光片组合的特点是激发滤光片和阻挡滤光片的传输光谱范围之间的间隔为530nm。在标准滤光片组合中，这个间隔约为495nm。与标准滤光片相比，新型滤光片增强了眼底所有部位的胶片曝光，尤其是黄斑区和脉络膜荧光。脉络膜血管系统的显示得到了改善，尤其是在黄斑区，并且黄斑区视网膜细节的可见性更好，但黄斑区以外视网膜血管的对比度略有下降。对于观察者来说，眼底可见性的提高以及老年受试者眼内介质中散射的减少，提高了使用新型滤光片拍摄的血管造影照片的整体质量。
