Supplementary Material for: Preservation of vision after early recognition of anterior ischemic optic neuropathy in a patient with sepsis

Non-arteritic ischemic optic neuropathy (NAION) can rarely occur in the setting of sudden vascular compromise, especially in patients with a “disk-at-risk” appearance. Anemia and hypotension are believed to be the main precipitators of shock induced NAION. Early recognition of this phenomena can prevent further visual loss and result in partial visual recovery. We here present a 56-year-old patient who developed NAION characterized by optic disc edema in both eyes and visual loss in the left eye secondary to hypotension in the setting of septic shock. He received aggressive blood pressure management which resulted in stabilization of vision in the right eye and likely prevented further visual loss in the left eye.
