摘要：Glaucoma is a serious eye disease, overtime it will result in gradual blindness. Early detection of thedisease will help prevent against developing a more serious condition. A vertical cup-to-disc ratio which isthe ratio of the vertical diameter of the optic cup to that of the optic disc, of the fundus eye image is animportant clinical indicator for glaucoma diagnosis. This paper presents an automated method for theextraction of optic disc and optic cup using Fuzzy C Means clustering technique combined withthresholding. Using the extracted optic disc and optic cup the vertical cup-to-disc ratio was calculated.The validity of this new method has been tested on 365 colour fundus images from two different publiclyavailable databases DRION, DIARATDB0 and images from an ophthalmologist. The result of the methodseems to be promising and useful for clinical work.
