Zusammenfassung
The diameter of the large retinal vessels is an important factor in retinal
microcirculation. A system configuration was developed that uses SLO images to
measure the diameter of retinal branch vessels off-line. The place for
measurement is defined in the image by the investigator, and the diameter is
measured automatically. The mean standard deviation of the diameter of arterial
vessels was 2.37\% and for veins 3.43\% by repeat measurement in sequential
pictures by optimal scanner settings. The reproduction of vessel diameters was
unsatisfactorily for repeat examinations. The course of these results may be
changes in the fundus image connected with changes in the position of the
scanner-bulbus (e.g., new examination, poor fixation). The scanner-bulbus
position is not yet precisely defined and not reproducible enough.
