Abstract

The object of an apparatus and a method for the analysis of retinal vessels is to improve the reproducibility of individually determined artery-to-vein ratios and to reduce the measurement uncertainty in determining the artery-to-vein ratio in order to substantially increase the individual validity of the determined values for vessel diagnosis. At least two images are recorded successively as an image sequence in a predetermined timed sequence adapted to the vasomotricity of the vessels and are evaluated such that a mean artery-to-vein ratio is formed from artery-to-vein ratios that are determined on the basis of the at least two images.
