Retinal Vessel Analysis - method, application and evidence from microvascular biomarkers
Learn more about Retinal Vessel Analysis and find out about our unique technology!
The Static Vessel Analyzer (SVA) measures the calibre of retinal vessels. The ratio of the arterial to the venous diameters shows risks such as a future cerebrovascular event. The preventive effect of a treatment, e.g. blood pressure lowering or blood sugar adjustment, is also observable and thus can be a positive motivation for the patient.
Using the Dynamic Vessel Analyzer (DVA), vessel reactions are tested. By stimulating the retina with flickering light, the smallest blood vessels dilate and the blood flow increases. This leads to a dilation of the larger retinal arteries and veins. This arises because the blood column interacts with the vascular endothelial cells and causes them to release more vessel dilating molecules (vasodilators). A missing or reduced dilation is thus a clear indication for an endotheliopathy. It is of great importance to recognize this condition because arteriosclerotic processes affect the endothelial cells at first. In the primary vascular dysregulation (e.g. as part of the Flammer Syndrome) the function of these endothelial cells is disturbed as well. This is why examination with the DVA has a wide application, especially in the diagnosis of glaucoma which is being associated with vascular dysregulation.

Imaging and Systems for Vessel Analysis in small animals
Our systems for Retinal Vessel Analysis for the specific application in small animals are perfect for contact-free imaging as well as functional diagnosis of retinal microcirculation. The animals can be examined non-invasivly and in vivo. This is the world's first system which brings a lot of new and different possibilities to researchers of various disciplines.
Imedos – the Expert of Retinal Vessel Analysis. The retinal microcirculation is a perfect window to the body. Imedos is using ocular transparency to analyze the structure and function of retinal vessels in humans and animal models. These results serve as valuable biomarkers in various medical disciplines. Important cohort studies could prove the relevance and clinical use of the biomarkers gained from Retinal Vessel Analysis.
