Long-standing eyelid myoclonia with absences (video-EEG)

In this video-EEG of a woman with long-standing eyelid myoclonia with absences, eyelid myoclonia is consistently induced by eye closure in a lit room. This is completely abolished when eye closure is performed in total darkness achieved with underwater goggles covered with opaque tape. (Contributed by Dr. C P Panayiotopoulos.)
