title: [Visual perseveration and palinopsia: a visual memory disorder?].
abstract: Visual perseveration and palinopsia are defined as the persistence or the reappearance of the visual image. These infrequent symptoms are thought to be linked to the right hemisphere posterior areas. We report a case of this syndrome in which the initial fixation was foveal. The palinoptic image was sometimes moving. This suggests that palinopsia is due to a dysfunction of the visual memory, rather than of the visual system: this dysfunction may be related to hyperactivity of the visual buffer.
