RAO education: To assess stroke risk in RAO, which action is recommended?

• A. Urgent blood work and carotid doppler
• B. Routine eye exam in 1 year
• C. Start antibiotics
• D. Refer for intraocular injection

Answer: (A)

Retinal arterial occlusion is an eye emergency that often signals widespread vascular disease and a risk of future stroke. The best immediate step is to assess that systemic stroke risk rather than just treat the eye. Urgent blood work helps reveal cardiovascular risk factors and potential coagulation issues, while a carotid Doppler study looks for carotid artery stenosis or plaques that could be a source of emboli leading to stroke. Identifying these issues promptly guides timely preventive actions, such as antiplatelet therapy, lipid management, and, if indicated, vascular referral. Delaying with a routine eye exam in a year doesn’t address the urgent systemic risk. Starting antibiotics isn’t appropriate for this vascular concern, and an intraocular injection doesn’t evaluate or reduce stroke risk.
