Objective: To report a case of a non-arteritic anterior ischemic optic neuropathy (NAAION) in a patient treated with Sumatriptan. Materials and methods: NAAION represents a severe affection that frequently determines irreversible visual acuity damage. The exact cause is yet to be identified, but is usually connected to the systemic status of the patient. We presented the case of a 53-year-old female patient who complained of visual acuity loss in her right eye, associated with inferior visual field (VF) damage. Patient history revealed migraine attacks, raised arterial blood pressure (BP), mitral valve insufficiency and dyslipidemia. Systemic treatment included Sumatriptan for migraine attacks and Bisoprolol for arterial hypertension. Results: A complete ophthalmologic examination was performed, including a visual field examination and optic coherence tomography. Interdisciplinary consults, along with inflammatory biomarkers, brain scan and cardiovascular Doppler echography were used to establish the final diagnosis. Considering the patient’s history, systemic medication, clinical picture, paraclinical findings and interdisciplinary check-ups, NAAION was established as a diagnosis. Discussion: NAAION occurs more frequently after the age of 50 years old and may be associated with systemic factors such as nocturnal hypotension, diabetes, atherosclerosis, sleep apnea. In the present case, the association of medically induced nocturnal hypotension and vasoconstriction led to optic nerve ischemia. Conclusions: In a patient with multiple pathology, we must consider the systemic therapy when performing any clinical examination.
