A 68-year-old woman presented with profound vision loss of 2-month duration in the right eye and 1-week duration in her left eye. This occurred in the context of craniopharyngioma that was twice resected and irradiated (54 Gy in 30 fractions) 9 months before her presentation. Ophthalmological examination revealed hand motion vision in the right eye and light perception vision in the left eye with poorly reactive pupils and bilateral optic disc pallor. A non-contrast MRI of the brain and sella showed significant reduction of the sellar mass. A repeat MRI of the brain and orbits with gadolinium showed pre-chiasmatic enhancement of both optic nerves. The diagnosis of radiation-induced optic neuropathy was made. Despite treatment with high-dose intravenous corticosteroids, 19 sessions of hyperbaric oxygen therapy, and 3 doses of intravenous bevacizumab, her vision worsened to no light perception in both eyes.
