The self-induction of epileptic seizures by eye closure.

Of 22 consecutive epileptic patients sensitive to intermittent photic stimulation, 7 were found to induce paroxysmal activity and/or seizures by a slow closure of the lids accompanied by eye rolling, which in 6 of the 7 was totally different from the movement normally carried out on voluntary eye closure to command. To identify the syndrome it may be necessary to monitor the EEG and oculogram for some 10 min or longer with the eyes open in a well-lit environment.
