Figures

Figure 1
Figure 1. Computerized Visual Field Grayscale Map. Humphrey Visual Field Analyzer SITA-based central 24-2 threshold test demonstrating a bilateral peripheral visual field defect (macular sparing pattern), predominantly affecting the right hemifields. Fixation loss, false-positive, and false-negative response rates were within reliable limits.

(A2) Left sagittal MRI (FLAIR): no structural abnormalities detected. (A3) [18F]FDG-PET 3D-SSP images (Cortex ID suite, GE Healthcare). (A4) Z-score projection of hypometabolism.
