[Depiction of chorio-retinal anastomoses with the help of computer-assisted fluorescent angiography (author's transl)].

We recently had the opportunity of evaluating the technique of computer analysis of fundus photography and fluorescein angiograms. Two angiograms were obtained over a period of three months from a patient with senile macular degeneration. At this time we are applying two techniques: black and white photographs with differential contrast enhancement, as well as photographs made with false colours, with and without contrast enhancement. Both of these techniques enables us to confirm the presence of chorio-retinal anastomoses at the site of the macular degeneration. We assume that this was caused by two occlusions of a choroidal venule.
