“…The frequency and significance of PFO in association with ocular circulatory disturbances were evaluated in forty patients with acute arterial occlusions of the posterior bulb segment through transthoracic and transesophageal echocardiography by Steuber and colleagues [16]. PFO was identified in nine patients and two of them showed that the potential source of paradoxical embolism was phlebothrombosis in their clinical history.…”

Central retinal artery occlusion (CRAO) represents one of the most devastating ophthalmic emergencies, since the inner two-thirds of the retina lose their blood supply. The acute obstruction of the central retinal artery is characterized by severe, sudden and unilateral painless visual loss and usually occurs secondary to an embolus of cardiovascular origin. A paradoxical thromboembolic event of the central retinal artery through patent foramen ovale is an exceptionally unusual clinical entity as well as a great diagnostic challenge since the source of initial thrombus formation requires extensive investigation. Herein, we aim to describe a patient with no significant comorbidities who experienced a paradoxical thromboembolic episode of central retinal artery associated with patent foramen ovale.

“…This condition is caused by a venous embolus that crosses the PFO or that is trapped in PFO [4][5][6]. Brain arteries are the most frequent localization of paradoxical embolism [4]; less commonly paradoxical embolism has been described in the upper limb [1], coronary [8], renal or retinal arteries [9].…”

IntroductionCoexistence of pulmonary embolism and systemic arterial embolism suggest the diagnosis of paradoxical embolism which suggests the presence of intracardiac defects such as patent foramen ovale (PFO).Case presentationA 42 year old man was found to have a paradoxical embolism in the systemic arterial circulation, in the setting of pulmonary embolism and deep vein thrombosis (DVT) in the lower extremities.ConclusionParadoxical embolism and intracardiac shunt should be immediately considered in a patient with pulmonary embolism and systemic arterial embolism. Diagnostic modalities included arteriogram and saline contrast echocardiography. Closure of intracardiac shunt is needed for patients who are at risk for recurrent embolic events.

Open foramen ovale in patients with arterial occlusions of the retina and optic nerve

Abstract: From our findings, it appears highly probable that ocular arterial occlusion is caused by paradoxical embolism. PFO should be taken into account in establishing a diagnosis, including diagnosis in elderly patients.
