Figure 9.12

Occipital paroxysms in their classical form with fixation-off sensitivity in a 10-year-old boy with Gastaut-type childhood occipital epilepsy (case 26 in ref1).

Occipital paroxysms occur as long as fixation and central vision are eliminated by any means (eyes closed, darkness, +10 spherical lenses, Ganzfeld stimulation). Under these conditions, eye opening is not capable of inhibiting the spikes. Symbols of the eyes open or closed without glasses denote that the recording was made with the lights on and whenever fixation was possible.

Symbols of the eyes open or closed with glasses denote that the recording was made when fixation and central vision were eliminated by any of the above means.
