Figure 1
At seizure onset (left arrow), the patient has a rightward horizontal conjugate eye deviation; the EEG shows rhythmic theta activity over the right posterior temporal region and rhythmic epileptic activity from the right temporal to right fronto-central regions, concomitant with the appearance of convergent strabismus due to adduction of the right eye without conjugate left eye abduction (right arrow). The patient's blinking (see blink artefact over frontal regions indicated by the right arrow) could be a semiconscious reaction to the sudden onset of diplopia due to ictal strabismus (when questioned postictally, the patient did not recall any symptom of double vision occurring immediately before loss of consciousness). Ictal tachycardia starts just after the blink. Sensitivity: 7 μV; LF: 0.53 Hz; HF: 70 Hz; speed: 30 sec/page.
