Which combination of symptoms is commonly associated with giant cell arteritis causing AAION?

• A. Fever, headaches, and jaw pain
• B. Cough and shortness of breath
• C. Nausea and vomiting without other symptoms
• D. Abdominal pain and back pain

Answer: (A)

Giant cell arteritis causing anterior ischemic optic neuropathy typically presents with systemic inflammatory symptoms plus jaw claudication. Fever and headaches reflect active vasculitis of large cranial arteries, and jaw pain during chewing points to involvement of branches of the external carotid system that can extend to the ophthalmic circulation. When the ophthalmic artery and its feeding vessels become inflamed, the optic nerve head loses blood supply, leading to the sudden, painless vision loss seen in AAION. The other symptom sets—cough with shortness of breath, nausea and vomiting without other signs, or abdominal/back pain—do not fit this cranial arteritis pattern and are more typical of other organ-specific diseases. In this context, recognizing fever, headache, and jaw pain helps identify the vascular inflammatory process that can threaten vision, prompting urgent evaluation and treatment.
