palinopsia
Pronunciation: pal-in-OP-see-ah
Persistence or recurrence of visual images after the stimulus has been removed from view.
Full Definition
Palinopsia is a rare visual phenomenon characterized by the persistence or recurrence of visual images after the original stimulus has been removed from the visual field. There are two main types: immediate palinopsia, where images persist continuously after looking away, and delayed palinopsia, where images reappear after a delay. This condition can result from various causes including occipital lobe lesions, migraine, seizures, or certain medications. The persistent images are typically described as trailing, smudging, or ghost-like duplications of recently viewed objects. Palinopsia can be highly distressing and may interfere with daily visual tasks, particularly reading and driving.
Usage
Usage note: Distinguish from normal afterimages by duration and quality of the persistent visual experience.
