Showing total number of scans demonstrating each type of pathology by Stratus and by SDOCT. Per cent missed specifies percentage of scans which were found to have pathology on the specified SDOCT device but was not visible on Stratus.
3D, three-dimensional; ERM, epiretinal membrane; PED, pigment epithelial detachment; SDOCT, spectral domain optical coherence tomography; SRF, subretinal fluid.
