Abstract

Anton syndrome is characterised by visual anosognosia. It results from damage to both occipital lobes, while the anterior visual pathways remain intact. We describe four cases of Anton’s syndrome. First case is that of a 73-year-old woman, who presented with two separate events of intraparenchymal brain haemorrhage, 4 years apart. Her first stroke affected the left and second affected the right occipital lobe. Bilateral occipital lobe damage resulted in cortical blindness. Second case is an 88-year-old man, who suffered from two ischaemic strokes, 2 days apart. Each stroke involved one posterior cerebral artery. This resulted in bilateral occipital and temporal lobe infarcts. Third case is a 64-year-old woman with chronic renal failure, who suffered bilateral occipital lobe infarction after haemodialysis, due to posterior reversible encephalopathy syndrome. Last case is that of an 80-year-old woman who suffered a basilar artery stroke, resulting in bilateral thalamic, temporal and occipital lobe infarction.
