From the Guidelines
The workup for a carotid ophthalmic artery aneurysm should begin with advanced neuroimaging studies, including a cerebral angiogram, CT angiography (CTA), and MR angiography (MRA), to determine the aneurysm's size, shape, and relationship to surrounding vessels 1.
Key Components of the Workup
- A comprehensive ophthalmologic examination is crucial to assess for visual deficits, as these aneurysms can compress the optic nerve or chiasm.
- Additional workup includes a thorough neurological examination to detect any focal deficits and assessment for subarachnoid hemorrhage if the patient presents with sudden-onset headache.
- Laboratory tests should include a complete blood count, coagulation profile, and renal function tests, particularly if endovascular treatment is being considered.
- For patients with multiple aneurysms or a family history, genetic testing may be warranted to identify conditions like polycystic kidney disease or connective tissue disorders.
Importance of Recent Guidelines
The most recent guidelines from the American Heart Association/American Stroke Association 1 and the American Heart Association 1 emphasize the importance of prompt and accurate diagnosis, as well as multidisciplinary collaboration among neurologists, ophthalmologists, and primary care physicians.
Considerations for Treatment
Treatment planning should be individualized, taking into account the aneurysm's characteristics, the patient's overall health, and the risks and benefits of observation, surgical clipping, or endovascular coiling 1.
Secondary Prevention
Secondary prevention strategies, including risk factor modification and antiplatelet therapy, should be implemented to reduce the risk of future ischemic events 1.

Workup for Carotid Ophthalmic Artery Aneurysm
The workup for carotid ophthalmic artery aneurysm involves a combination of clinical evaluation, imaging studies, and sometimes, surgical intervention.
- The diagnosis of carotid ophthalmic artery aneurysm is typically made using angiography, which can help identify the location, size, and morphology of the aneurysm 2.
- Detailed angiographic studies employing various projections are required before treatment can be planned 2.
- Magnetic resonance angiography (MRA) can also be used to evaluate symptoms such as vertigo or headache 3.
- The treatment of carotid ophthalmic artery aneurysm depends on various factors, including the size, location, and symptoms of the aneurysm, as well as the patient's overall health.
Treatment Options
The treatment options for carotid ophthalmic artery aneurysm include:
- Endovascular treatment: This involves using minimally invasive techniques to treat the aneurysm, such as coiling or flow diversion 4.
- Microsurgical clipping: This involves surgically clipping the aneurysm to prevent further bleeding 3, 5, 6.
- Combined approach: This involves using a combination of endovascular and microsurgical techniques to treat the aneurysm 4.
Surgical Considerations
When performing surgery for carotid ophthalmic artery aneurysm, it is essential to:
- Avoid optic nerve injury caused by retraction and/or the heat of the drill 3.
- Use meticulous microsurgical technique during anterior clinoidectomy, aneurysm dissection, and clip application to optimize visual outcomes 5.
- Consider aggressive medical management postoperatively to potentially decrease the incidence of delayed visual deficits 5.
