Cortical blindness is one of the rare neurological condition characterized by binocular vision loss due to insult in the occipital cortex. Pupillary light reflex are preserved as anterior visual pathway is intact. One of the rare complication of cortical blindness is Anton Babinski Syndrome. This syndrome results from damage to visual association cortex (brodmann area 18, 19) along with primary visual cortex (brodmann area 17) [1, 2]. Discussion
Anton Babinski syndrome is a condition in which patient disaffirm their blindness (visual anosognosia) in spite of complete amaurosis of central origin (cortical blindness). In this, patient adamantly claim they are capable of seeing and/ or experiencing strange visual hallucinatory episodes, consequently resulting in confabulation [1].
This syndrome was first described by French writer Michel de Montaigne (1533-1592). In late 1890s Gabriel Anton (1858-1933), Austrian neuro-psychiatrist noted three patients, one with cortical blindness one with deafness and one with left sided hemiparesis all lacking self-perception of their deficit. Joseph Babinski (1857-1932), French neurologist in 1914 used the term ‘Anosognosia’ to describe hemiplegic patients …show more content…
Others cause being obstetric complication such as pre-eclampsia and hemorrhage resulting in hypo-perfusion [5], Hypertensive encephalopathy [6], MELAS (Mitochondrial myopathy, Encephalomyopathy, Lactic Acidosis and Stroke like episodes) [7] Adrenloeucodystrophy [8], cardiac surgery [9], head trauma [10], Angiitis (auto-immune) of central nervous system [11]. Angiographic procedures which disrupts blood brain barrier, coexisting with hypotension, embolism and vasospasma can also causes cortical blindness [12]. Any condition resulting in systemic hypoxia mainly affects occipital cortex because it lies distal from central cerebral vasculature
