Visual perseveration


One of the varieties of metamorphopsias in which a visual image either persists or recurs even after the original stimulus is no longer present. The image of the object may subsequently become superimposed upon a current visual image or scene. While this persistence of a previous image usually lasts for a period of minutes, it may recur hours or even days later. As is true of the other metamorphopsias, this phenomenon is most commonly associated with parietal-occipital or temporal-occipital lesions, seizures, and toxic or metabolic disorders.
