| Abstract(in English) | Glaucoma is the leading cause of blindness in Japan. The ratio of the maximum vertical diameters of cup and disc is one of the signs for glaucoma. In general, ophthalmologists determine a cup region by using the kinks of the blood vessels on a retinal fundus image. However, there are inter-reader variations among ophthalmologists in interpretation of such kinks, which makes it also difficult to develop a computer algorithm for automatic detection of the kinks. Therefore, the aim to this study was to develop a computerized algorithm for quantitative measurement of glaucomatous index, and our proposed method employed a profile of optic disc for estimation of cup borders. The area under the ROC curve of 0.942 using 80 retinal fundus images (25 glaucoma cases, 55 normal cases) for distinction between glaucoma and normal cases indicates the usefulness of this method in the diagnosis of glaucoma. |
