![]() ![]() The average sensitivity, accuracy, and specificity of the proposed system are 87, 79 and 72%, respectively, on the Armed Forces Institute of Ophthalmology dataset when correlated with clinical annotations and CDR computer generated values. Based on calculated CDRs, the system classifies the subject as normal or glaucomatous. A novel criterion for horizontal/flat cup diameter based on the average RPE break points is proposed. ![]() The method uses both the ILM layer and RPE breakpoints for a cup and disc calculation, respectively. During RPE segmentation, a new ‘centroid based thresholding’ method is proposed to remove extended ILM regions. A new colour channels mean based quality assessment step is applied to segment out ILM layer for different quality images. A novel method for extraction of the inner limiting membrane (ILM) and retinal pigment epithelium (RPE) layers from optical coherence tomography scans is proposed. Glaucoma is a blindness causing eye disease if not treated in time and caused by the increase in the cup-to-disc region (CDR).
