Figure 1.
The top panel shows an example of the calculation for a defect with 30° angular width. Correct detections are identified as red triangles, meaning that the location is both mapped to a structural defect and actually affected. Only locations within the annulus delimited by the black ellipses are considered. The bottom panels represent the percentage of correct detections (blue-shaded bar chart), without accounting for displacement, at different positions around the optic nerve head and different angular widths of the defect. The maximum extent of the polar axes corresponds 100% (perfect detection, no different from using the correct displacement model). The dashed lines delimit the sectors where macular bundle defects are more commonly found. I, inferior; T, temporal; S, superior; N, nasal. From Leung et al.

Pattern deviation probability map of a 10-2 full-threshold test mapped to an en face reflectivity map of the RNF layer, with and without displacement. The locations highlighted in red are those where the structure–function agreement was improved by displacement.
