 Abstract
Posterior cerebral artery (PCA) infarction is a common and important cause of acute painless visual loss. To our knowledge, nearly total blindness due to bilateral PCA infarction is rare. Patent foramen ovale (PFO) is one of the crucial causes of cryptogenic stroke and it should be regarded as a cause of stroke when cerebrovascular stenosis or other cardioembolic causes of stroke is absent. We report a case of bilateral PCA infarction due to PFO presenting as nearly total blindness.
