A 7-year-old boy presented with episodic blindness for the last 2 months with occipital paroxysms and fixation-off sensitivity on electroencephalography (EEG). The clinico-EEG features were suggestive of idiopathic childhood occipital epilepsy of Gastaut. The interesting phenomenon of fixation-off sensitivity is discussed.
