Cardiovascular Morbidity and Mortality After Amaurosis Fugax

Amaurosis fugax is an episode of transient vision loss related to a vascular origin and is considered a form of transient ischemic attack (TIA). Patients with TIAs or amaurosis fugax often have underlying cardiovascular comorbidities and thus have a higher risk of cardiovascular sequelae. However, management of amaurosis fugax can be variable, and patients with amaurosis fugax may be less likely than patients with cerebral TIA to undergo carotid endarterectomy (CEA) within the recommended timeframe.1,2 A study of 20 ophthalmologists showed that only 30% knew that CEA was recommended within 14 days of amaurosis fugax.3 A better understanding of the risk of subsequent stroke is important to triage patients with amaurosis fugax because earlier intervention may prevent subsequent vascular events.
