Fig. 3From: Spatial agreement between Goldmann visual field defects and fundus autofluorescence in patients with birdshot chorioretinopathyBland-Altman plot representing the study eyes (red circles) showing the mean area of Goldman visual field (GVF) and fundus autofluorescence (FAF) versus the difference (GVF-FAF). The plot demonstrates the individual variation in agreement. The mean difference between GVF and FAF is negative, indicating a greater extent of the area of FAF defects compared to scotomas on GVFBack to article page
