Abstract

A method is presented that allows the quantitative determination of the blood flow in retinal arteries in human beings. Television fluorescein angiograms are used as input. This method does not need any gauge procedures since all the necessary information is taken from the image itself. Also, the patients' eye movements do not introduce errors because their influence is removed by the computer program.
