A Study of Hypertensive Retinopathy Changes for Stroke Prediction

Hypertensive retinopathy is an ailment that is highly connected to hypertension
which help in stroke prediction. The presence of hypertensive retinopathy is diagnosed
through image processing on the fundus image to identify the possible microvascular
retinal abnormalities signs that lead to hypertension. Arterio-Venous Ratio (AVR) value
is one of the main indicator of hypertensive retinopathy, useful for grading severity of
hypertensive retinopathy and for prediction of risk of stroke. Image preprocessing were
performed in this work to extract vessels in fundus image. In this thesis, fundus images
were acquired from VICAVR and DRIVE databases.
