Retinal arterial occlusion due to embolism of suspected cardiac tumors -- report on two patients and review of the topic.

Background: Ophthalmic complications due to heart tumors are rare.

Methods: This case report describes two patients with ocular complications, caused by a suspected cardiac tumor. A 56-year-old woman with arterial hypertension had a severe episode of headache coinciding with an acute loss of vision in her right eye and left-sided hemiparesis. A 20-year-old woman noticed sudden transient visual loss in her right eye.

Results: The 56-year-old woman had an infarction on the right side of the middle and posterior cerebral arteries and, simultaneously, a central retinal artery occlusion (CRAO) in her right eye. Echocardiography revealed a tumor in the left atrium. The tumor disappeared after treatment with phenprocoumon within a few days. The diagnosis of a cardiac thrombus was made. The 20-year-old woman noticed recurrent episodes of sudden, transient visual loss in her right eye. A branch retinal arterial occlusion (BRAO) in her right eye was diagnosed. Echocardiography revealed a myxoma in the left atrium. The tumor was successfully excised surgically.

Conclusions: In any vascular disturbance in the eye suspected to be embolic in origin, echocardiography should be carried out in order to exclude the presence of a heart disease.
