For the past two days, for a couple of hours, my 18 year old daughter cannot keep her eyes from closing and rolling back in her head. She will be busy doing something and it is like she has no control over her eyes. She has to literally hold the lids open to keep them from shutting, even though she is wide awake. Has anyone heard of this bizarre symptom and know what it is caused by?

Well, there's this:

Clinical features of blepharospasm include involuntary eye closing aggravated by bright lights, wind, pollution, smoke, emotional stress, fatigue. This eye closing may interfere with reading, driving, watching television, and other visual activities, and is rarely associated with retro-orbital pain. Blepharospasm may be associated with other dystonic disorders, such as oromandibular or cervical dystonia, and usually occurs in the 5thto 7thdecades of life. There is no clinical difference between the eye findings of primary and secondary blepharospasm with the possible exception that primary blepharospasm is sometimes relieved with a sensory trick (touching face, humming, singing, talking, pinching skin), and this has not been documented in secondary cases.

Thank you so much for going to the trouble to find out this information! It is very much appreciated!!
