[Evaluation of fluorescein angiograms using the multitemporal technic].
If there are differences in the density of black-and-white photographs of the fundus oculi taken at different times, they may be transformed into color differences by means of the multitemporal technique. A multitemporal picture is obtained by additive color mixing of black-and-white photographs transilluminated at the same time with one primary color each. Since, in a serial angiogram, the interrelation between the film density and the passage of the fluorescein concentration in the fundus oculi is known, it is possible to draw conclusions from the multitemporal picture regarding phase differences and changes in the curve shape of the fluorescein concentration.
