Using Point-of-Care Ultrasound for Early Identification of Central Retinal Artery Occlusion

Abstract

Central Retinal Artery Occlusion (CRAO) is the partial or complete blockage of the central retinal artery presenting as acute painless monocular vision loss with increased risk in those with cardiovascular disease. Diagnosis of CRAO requires a dilated fundoscopic exam performed by an Ophthalmologist. In resource limited hospitals, access to these expertise and resources may be difficult. Early recognition of CRAO in the emergency department (ED) can lead to reduced negative consequences and reduced cost to healthcare. Here we present a case using Point-of-Care Ultrasound (POCUS) to identify CRAO in a patient.
