The Spectrum of Epilepsies with Fixation off Sensitivity: A Case Report and Review of Literature

Abstract

Fixation off sensistivity is a electrographic marker of occipital lobe epilepsy. The report describes a 11 year old with infrequent seizures responsive to treatment with valproate who was found to have occipital epileptiform discharges which appeared only during eye closure. The typical phenomenology of visual aura or autonomic seizures as seen in benign occipital epilepsies is not mandatory to be associated with FOS. The spectrum of various epilepsy syndrome which display this typical finding is discussed.

Photo-Dependent Reflex Seizures—A Scoping Review with Proposal of Classification

“…Seven articles present seizures provoked by lack of light or lack of fixation of eyesight. There are two types of stimulation-fixation-off and scotosensitivity [39][40][41][42][43][44][45].…”

“…Studies presented results for sample with a broad age range including adults without separate data presentation for only pediatric participants were included. Overall, 17 reports were included in the review [5,[30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45] with three of the included articles being case reports. Based on the guidelines, 17 publications linked to the research topic met the criteria for inclusion in the scoping review (Figure 1).…”
