Abstract :
The design and implementation of a video fluorescein and angiography system for the visualization and investigation of chorioretinal perfusion is described. With state-of-the-art video technology, high-quality fluorescein angiographic images are recorded in real time. Digitization of the images provides an indicator-dilution method for determining blood flow throughout the retinal vascular bed. Clinical measurements with this system show that the perfusion of the macula, optic disk, and choroid can be examined simultaneously as well as flow in the major retinal vessels
