·电视荧光血管造影术是为了获得荧光素稀释曲线(DromoF)[源自希腊语：δρομο，意思是流动。我们创造这个词是因为稀释曲线不能真正测量血液循环，或简单地测量稀释，而是提供循环中荧光素运输的真实测量！])来自单个视网膜血管。光纤将光从视频屏幕上的单个视网膜动脉、静脉或任何其他视网膜区域传输到光电倍增管。经过低通电子过滤后，将稀释曲线记录在条形图记录仪上。所考虑的测量都与时间有关：动脉和静脉曲线初始时刻之间的时间间隔；最大时刻之间的时间间隔；动脉和静脉曲线上升时间。可以看出，(1)该方法足够灵敏，能够检测到病理病例中的数量变化；(2)由于血管的不同部分之间存在很大的差异，因此很重要的一点是指定记录视网膜DROX照片的位置。(ARCH眼科95：302-307,1977)
• Television fluoroangiography is used in order to obtain fluorescein dilution curves (dromofluorograms [From the Greek word: δ ρ ο μ ο, which means flowing. We coined this word because dilution curves do not afford a true measurement of the blood circulation, or simply of a dilution, but of the fluorescein transport in the circulation!]) from single retinal vessels. An optical fiber conveys the light from a single retinal artery, vein, or any other retinal area on the video screen to a photomultiplier. After lowpass electronic filtration, the dilution curves are recorded on a strip-chart recorder. The measurements considered are all related to time: the time interval between initial instants of the arterial and venous curve; the time interval between maximum instants; the arterial and venous curve rising times. It is seen that (1) the method is sensitive enough to enable variations in the quantities in pathologic cases to be detected; (2) owing to the great variability from part to part of the vessels, it is important to specify where the retinal dromofluorogram has been recorded.
