Recurrent Bilateral Occipital Infarct with Cortical Blindness and Anton Syndrome

Abstract

Bilateral cortical blindness and Anton syndrome, are most commonly caused by ischaemic stroke. In this condition, patients have loss of vision but deny their blindness despite objective evidence of visual loss. We report a case of a patient with multiple cardiovascular risk factors who developed recurrent bilateral occipital lobe infarct with Anton syndrome. A suspicion of this condition should be raised when the patient has denial of blindness in the presence of clinical and radiological evidence of occipital lobe injury. Management of this condition should focus on the underlying cause, in which our patient requires secondary stroke prevention and rehabilitation.

Cortical Blindness Induced by Cerebrovascular Disease: A Case Report

“…Oksipital alanda bilateral tutulumlara bağlı olarak bilinçli ya da bilinçsiz olarak görme azlığı gelişebilmektedir (2,3,5,8). Misra ve ark.nın Hindistan'dan bildirdikleri preeklamsi hastasında bilateral oksipital lobda enfarkta bağlı gelişen Anton-Babinski sendromunda ise hasta sekelsiz iyileşmiştir (3).…”

Anton syndrome during oxygen-ozone therapy

“…Bilateral cortical blindness that called Anton syndrome is generally seen after an ischemic stroke [3]. Bilateral infarcts of posterior cerebral arteries are associated with Anton syndrome, and primary visual cortex and visual association area effect from these infarcts [3].…”
