Area of Science:

Ophthalmology
Vascular Neurology
Cardiology

Background:

Subclavian steal syndrome involves reversed blood flow in the vertebral artery due to subclavian artery stenosis or occlusion.
Traditionally linked to vertebro-basilar insufficiency, it can also cause diverse ischemic symptoms.

Observation:

Three patients with subclavian steal syndrome underwent eye exams.
Presentations included Hollenhorst plaques, fibrino-platelet plaques, and asymptomatic cases.

Findings:

Ocular manifestations can be presenting signs of subclavian steal syndrome.
The condition's presentation depends on collateral cranial artery patency.

Implications:

Optometrists should recognize ocular signs of subclavian steal syndrome for timely referral.
Evaluation of extracranial arteries is vital for patients with suspected vertebro-basilar or carotid ischemia.
