Computation of retinal fundus parameters for stroke prediction

ABSTRACT

Stroke is one of the cerebrovascular causes of adult impairment in most of the developing nations worldwide. Early prediction of stroke is still a challenge in the field of biomedical research. Retinal fundus images can be analysed for stroke prognosis as retinal arterioles and cerebral arterioles are of same embryological origin. This research work mainly analyzes the variations in retinal vasculature in predicting the risk of stroke by computing global parameters like fractal dimension and local parameters like branching coefficients and angle, asymmetry factor and optimality ratio for both arteries and veins. Regression analysis has been performed to locate the relevant retinal features and those parameters are given to a Naïve Bayes classifier which gives promising results.
