[Palinopsy as a manifestation of neuro-ophthalmological disorders].

Palinopsy or perseveration of a pre-seen image is impaired visual perception as preservation or repeated occurrence of a visual image of an object after its disappearance from the field of vision. Patients with palinopsy are rather frequently encountered in neurological practice; however, they may first visit an ophthalmologist in some cases. The author describes a few cases in which palinopsy was the first manifestation of cerebral arteriovenous malformation, ischemic stroke, and multiple sclerosis, as well as a case of visual perseverations while using narcotic drugs. The correct evaluation of a patient's status and the determination of the scope of additional studies are of great importance in this situation.
