The greater pallor in the left eye indicates optic atrophy. Optic atrophy, manifesting as optic disc pallor, rarely exists in isolation. As such, it is imperative to look for associated optic nerve dysfunction to separate the mimicking conditions from true optic atrophy. Associations that would indicate true optic atrophy include visual field loss, visual acuity reduction, dyschromatopsia, relative afferent pupil defect (when unilateral or asymmetric) and retinal nerve fiber layer damage.
