Das Video-Simultan-Fluoangioskop

: The present paper describes the video simultaneous fluoangioscope. It is based on the Rodenstock simultaneous fluoangioscope, an accessory for use with the laser slit-lamp. It has been proving its clinical usefulness since 1984. Hitherto, its optical superimposition of the corresponding fluorescein angiograph onto the actual fundus view was based on angiographic film as an information carrier. Digital fluorescein angiography (videoangiography) has meanwhile made film superfluous while at the same time opening up new possibilities. The video simultaneous angioscope superimposes a selected video half-frame onto the fundus, thus transferring angiographic data and facilitating safe and easy coagulation. The advantages and new possibilities arising from them are discussed and the system peripherals are described. An illustration shows the superimposition of the images when looking through the slit-lamp.
