Amaurosis fugax is transient monocular vision loss due to retinal ischemia and requires what?

• A. Ophthalmic surgery
• B. Observation only
• C. Antidepressant therapy
• D. Cerebrovascular accident workup and usually admission

Answer: (D)

Amaurosis fugax is a transient retinal ischemia that usually results from emboli or reduced blood flow related to ipsilateral carotid artery disease. Because this event is a warning sign for a possible stroke, it requires urgent cerebrovascular evaluation and typically admission. The goal of the workup is to identify the source of the retinal ischemia and assess stroke risk: urgent brain imaging to rule out an ongoing neurological deficit, vascular imaging such as carotid duplex ultrasound or CT/MRA to evaluate carotid stenosis, and cardiac evaluation for other embolic sources, along with appropriate labs. Management focuses on preventing another event with antiplatelet therapy, risk-factor modification, and addressing carotid disease if significant stenosis is found, sometimes with revascularization. Ophthalmic surgery, antidepressants, or simply observing without a full vascular workup would not address the underlying risk, making cerebrovascular evaluation and usually admission the correct approach.
