“…The most common cause of cortical blindness is PCA occlusion 4. When the terminal bifurcation of basilar artery is involved in a thrombo-embolic event, resulting stroke can be bilateral 5. This was the cause in our fourth case.…”

Anton’s syndrome: a rare and unusual form of blindness

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.

“…Where there is a bilateral ischemia of the occipital cortex, it is possible that the occlusion lies more proximal in the PCA at the basilar artery bifurcation. Occlusion on of area should raise suspicion of a thrombo-embolic event [ 3 , 7 ]. In our case, a basilar artery embolism could not be ruled out; however, given the varying degree of hypoattenuation ( Fig.…”

“…Cortical blindness occurs where there is damage to the visual cortex of the occipital lobe, with sparing of the anterior visual pathways. Most commonly cortical blindness is caused by infarction [3] . In this case, we discuss a combination of Anton syndrome secondary to bilateral occipital infarction.…”
