Abstract
A 78-year-old man suffered sudden visual loss of his right eye. Five years earlier, he had experienced vision loss of his left eye due to central retinal artery occlusion (CRAO); back then, the etiology for the CRAO was not established. Current ocular ultrasound depicted a hyperechoic spot within the optic nerve in both eyes. Echocardiography identified a calcified mass adherent to the mitral valve as the embolic source of the CRAO. This case shows the value of ocular B-mode ultrasound in demonstration and proof of the etiology for CRAO.Keywords
