Monocular central retinal artery occlusion caused by bilateral internal carotid artery hypoplasia complicated with patent foramen ovale: a case report and review of literature.

ABSTRACT:

Background

Central retinal artery occlusion (CRAO) is an emergent ophthalmic disease which is commonly caused by atherosclerosis, thromboembolism, and arteriospasm. Here, we report a case of CRAO which is caused by extreme rare bilateral internal carotid artery (ICA) hypoplasia complicated with patent foramen ovale (PFO). The cardiogenic emboli blocked central retinal artery through unclosed foramen ovale and specific blood flow pathway.

Case presentation

This report describes a case of a 46-year-old woman sudden onset with amaurosis fugax for about 20 min and persistent visual impairment of left eye. Fundus fluorescein angiography shows the arm-retinal circulation time of left eye is 25 s, indicating that the occlusion occurs in the pathway from aortic arch to ophthalmic ar
