Abstract
This paper aims to study the blood pressure and flow at any site (or node) based on the branching asymmetry, the number of nodes and elements of a branching tree in the real retinal vascular structures. The analysis of blood flow in the circulatory system is based on Navier-Stokes equation, Poiseuille flow and an asymmetry parameter in order to gather information on the pressure field distribution as well as flow profile. Two retinal vessel geometries were investigated, i.e. normal human eye and diabetic retinopathy. The measured branching asymmetry is 0.4. Only two exceptions were established for diabetic retinopathy images. For the analyzed structures, the pressure gradient have almost similar profiles indicating that the overall behavior of pressure drop in all the vessels remains very much unaltered. Changes in the blood flow profiles were highlighted for diabetic retinopathy pathology (p < 0.001). This study is a first step in a right direction toward personalized medicine for pathologies related to the dynamics of blood flow.
