Retinal Vessel Analysis for the Morphological and Functional Examination of a Central Microcirculation Area – A New Clinical Method

Purpose: Changes of retinal blood vessels have been known in a number of vascular systemic diseases for a long time. The examination by a ophthalmoscope performed usually in hypertensive patients gives hitherto a subjective assessment of the morphological condition according to a qualitative scale. Method: The retinal vessel analysis is based on measured vessel diameters and their local and temporal changes. The static vessel analysis (SVA) examines quantitative vessel parameters in one single image of the fundus, i.e., the arterio-venous ratio. Signs of retinopathy were evaluated additionally in the image. The…
