Fig. 1

Representative cases of differences in detecting diffuse retinal nerve fiber layer (RNFL) defect between the red-free fundus photographs (left panel) and en face structural images (right panel). a, b The red-free fundus photographs show a diffuse RNFL defects, while the en face images clearly show localized RNFL defects. c The image shows a diffuse RNFL defect in the inferior hemifield, both in the red-free fundus photograph and the en face image. The peripheral borders of the defect in the en face image are indistinct. d The red-free photo shows a diffuse RNFL defect in the inferior quadrant; however, the en face image shows no RNFL defect
