An Elementary Method for the Computation of Artery to Vein Ratio in Fundus Images

Abstract

Medical research has shown that the artery to vein ratio can be used to detect Hypertensive Retinopathy. This ratio can be calculated by carefully studying the fundus images of the patients. Modern softwares can be used to process these images. This article will describe a simple method to compute the ratio of mean artery width to mean vein width. The images for testing of the described method have been taken from local eye clinic run by Althea Barbosa, Goa and few have been collected from online database STARE and DRIVE.
