1. These episodes of polyopia can last from seconds to hours. 2. Most cases of polyopia are accompanied by another neurological condition. 3. Thus, polyopia results from altered coding of contour information by neurons near the lesioned area. 4. In cases of epilepsy, polyopia is often experienced alongside palinopsia as these two conditions share an epileptic mechanism. 5. This mechanism may explain why polyopia extending into a patient s scotoma occurs following damage to primary visual cortex. 6. In other cases of polyopia , it is necessary to determine all other present visual disturbances before attempting treatment. 7. Further research should be conducted to determine if the treatment of associated neurological disturbances can reduce the effects of polyopia . 8. Polyopia is often accompanied by visual field defects ( such as the presence of a scotoma ) or transient visual hallucinations.9. Infarctions, tumors, multiple sclerosis, trauma, encephalitis, migraines, and seizures have been reported to cause cerebral polyopia . 10. Neurological imaging can be performed to determine if there are present occipital or temporal lobe infarctions that may be causing the polyopia .
