- Abstract: This a case report on a rare case of denial of visual perception termed as inverse Anton syndrome. It is a rare extension of perception without awareness in which, specific brain lesions affected a patient’s visual abilities. A 66-year-old Malay gentleman presented with sudden onset of the painless bilateral total loss of vision with expressive aphasia for 2 days. His visual acuity was 6/12 in the right eye and 6/48 in the left eye. However, he was insistent that he could not see but did not request any form of assistance for his blindness. He also had neurological signs suggestive of parietal lobe syndrome. Brain imaging showed subacute left middle cerebral artery territorial infarct with no occipital lobe involvement. The denial of visual perception by this patient may be explained by a disconnection of parietal lobe attentional systems from visual perception
