The optic nerve shows moderate cupping but there is a prominent inferior notch. The normal sheen of the nerve fiber layer is absent in a distribution radiating temporally from this notch due to cellular loss. The notch and nerve fiber layer defect can be more easily visualized on optical coherence tomography.
