Fig. 1. Serial Humphrey perimetries and high-resolution MRI of compressive optic neuropathy with a monocular inferior altitudinal visual field defect (VFD). A: Initial Humphrey perimetry shows an inferior altitudinal VFD in the left eye that is more severe on the nasal side than on the temporal side. Follow-up perimetry demonstrates an aggravated VFD and subsequent recovered visual field after surgery. B: Axial contrast-enhanced (CE) T1-weighted MRI with fat suppression (FS) showing an optic nerve meningioma (arrow), which is not clearly defined on T2-weighted and noncontrast T1-weighted images. C: Coronal T1-weighted MRI showing a meningioma (arrow) on the optic canal compressing the optic nerve in a medial downward direction. D: Schematic representation showing the VFD presenting according to the direction of the optic nerve compression.
