[Use of videoangiography of the retina]

A system is presented with the help of which high-quality visual presentation of fluorescein angiographies is possible. The individual elements of the unit are described (TV camera, light source, adapter for the TV camera, fundus camera, video recorder, video timer). The filming process is less strenuous for the patient than serial angiography since he is no longer dazzled by high-intensity light. The pictures are available immediately after filming, thus eliminating both the cost of developing and the delay involved. The examiner can make picture adjustments during filming. The high degree of resolution of this examination method in proportion to the time required for it makes a precise analysis for the physiological and pathological hemodynamics of the retinal- and choroidal blood vessels possible.
