[Utility of low light level television cameras for the fluorescein angiography of the retina (author's transl)].

A survey of the major proportion of low-light level TV cameras available on the German market is described. A comparison and an assessment of the applicability of televised fluorescein angiography were carried out with the aid of technical data and measured results. It became evident that some systems were practicable for clinical use. With those it was possible to record angiograms at minimal illumination levels and patient inconvenience was reduced significantly. Measurements of blood flow parameters were possible with good temporal and geometrical resolution and full reproducibility.
