“…2 Most visible emboli are associated with internal carotid artery stenosis/occlusion, 3,4 although some can also arise from aortic arch atheroma or cardiac chambers. 5,6 Although frequently asymptomatic, retinal embolism is associated with increased mortality risk. 7,8 A few population-based studies reported retinal embolus prevalence and associated factors.…”

“…But Cardiogenic emboli are a very rare cause of CRAO. While atrial fibrillation and left ventricular dysfunction were shown to be the most common cardiac sources, extracardiac sources (mainly aortic and carotid plaques) are associated with CRAO in the large majority of patients [ 4 ]. Unfortunately, the source of embolism remains unclear in about 45 % of the patients [ 5 ].…”

BackgroundCentral retinal artery occlusion (CRAO) is an ocular emergency and most of the cases present with painless sudden persistent loss of vision in the range of counting fingers to perception of light. The presentation of CRAO is associated with a variety of medical conditions. We report a rare case of CRAO associated with persistent truncus arteriosus (PTA) and single atrium in a female patient.Case presentationA 23-year-old woman was admitted due to sudden painless visual loss in the left eye. On examination visual acuity of light-perception was noted in the left eye with a left relative afferent pupillary defect. Fundoscopic examination revealed retinal ischemic whitening, constriction of the arteriole and venule with segmentation and typical “cherry-red spot” suggesting CRAO. The patient was treated with ocular massage and anterior chamber paracentesis. She was commenced on 150 mg of aspirin and also received hyperbaric oxygen therapy. An echocardiogram revealed PTA and single atrium. A diagnosis of CRAO associated with PTA and single atrium was made.ConclusionThe ophthalmologist should enquire about congenital and acquired cardiac abnormalities in patients with CRAO and consider such abnormalities to be possible sources of emboli.

Lesions of the Mitral Valve as a Cause of Central Retinal Artery Occlusion: Presentation and Discussion of Two Cases

2010

We present two cases of mitral valve lesions that manifested with unilateral blindness caused by central retinal artery occlusion (CRAO): Case 1. A 68-year-old woman was admitted to our clinic for sudden blindness. Retinal artery angiogram showed CRAO. Transthoracic and transesophageal echocardiography (TEE) documented a mass attached to the ventricular side of the posterior mitral leaflet, which at pathology was identified as a blood cyst. Case 2. A 67-year-old man was admitted for a sudden unilateral painless loss of vision. Retinal angiogram documented CRAO, and TEE showed a highly mobile, spherical, lesion on the atrial side of anterior mitral leaflet. In this case, the pathological finding was a degenerated calcified thrombosis. We report on two cases of very rare abnormalities of the mitral valve presenting with a very rare embolic complication, i.e., CRAO. Like for cryptogenic stroke, transesophageal echocardiography plays a central role in the diagnosis of cardiogenic embolic sources.

Echocardiographic Findings of Patients With Retinal Ischemia or Embolism

Abstract: Echocardiography frequently identifies lesions of the heart or aortic arch that can act as potential sources for retinal ischemia or embolism. Further studies are needed to evaluate the prognostic and therapeutic relevance of these findings.
