[Clinical aspects, differential diagnosis and evolution of visual epileptic seizures in children].
We studied 13 boys and girls, treated for ictal visual episodes, followed-up in the Center for Epilepsy of the University of Modena. In 10 cases visual symptoms (amaurosis, hallucinations, and illusions) started between 6 and 14 years, associated with occipital EEG anomalies. In 6 cases, EEG abnormalities (sharp-waves, slow waves, spikes, spike-waves) disappeared after eyes opening. In the history of half of our cases, there was no significant antecedent. Normal intelligence and behaviour were present in all cases. Only in one case, CT demonstrated bilateral occipital calcifications. In the other 9, visual ictal symptoms disappeared after antiepileptic treatment. We think that these last cases present the characteristic features of Benign Occipital Epilepsy described by Gastaut (1982-1985). On the basis of our results, we can confirm the existence of this syndrome, even if it is rare. Nevertheless, 3 of our cases with visual symptoms, don't show the typical picture of BOE, and must be diagnostically distinguished from psychiatric disorders, basilar migraine, and other partial epilepsies.
