In this article, a computerised DR grading system, which digitally analyses retinal fundus image, is used to measure foveal avascular zone. A v-fold cross-validation method is applied to the FINDeRS database to evaluate the performance of the DR system. It is shown that the system achieved sensitivity of >84, specificity of >97 and accuracy of >95 for all DR stages. At high values of sensitivity (>95), specificity (>97) and accuracy (>98) obtained for No DR and severe NPDR/PDR stages, the computerised DR grading system is suitable for early detection of DR and for effective treatment of severe cases. © 2011 International Federation for Medical and Biological Engineering. date: 2011 type: Article type: PeerReviewed identifier: Ahmad Fadzil, M.H. and Izhar, L.I. and Nugroho, H. and Nugroho, H.A.
