| 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.
