Cortical blindness refers to a visual loss induced by a bilateral occipital lesion. The very strong cooperation between psychophysics, cognitive psychology, neurophysiology and neuropsychology these last 20 years as well as recent progress in cerebral imagery have led to a better understanding of neurovisual deficits such as cortical blindness. It thus becomes possible now to propose an earlier diagnosis of cortical blindness as well as new perspectives for rehabilitation in children as well as in adults. On the other hand, studying complex neurovisual deficits such as cortical blindness is a way to infer normal functioning of the visual system.
