Well, maybe, except drooping of the eye is not listed an as effect of dystonia. For the record, the closest according to wiki are:

Blepharospasm: The patient experiences rapid blinking of the eyes or even their forced closure causing functional blindness.

Oculogyric crisis: An extreme and sustained (usually) upward deviation of the eyes often with convergence causing diplopia (double vision). It is frequently associated with backward and lateral flexion of the neck and either widely opened mouth or jaw clenching. Frequently a result of antiemetics such as the neuroleptics (e.g., prochlorperazine) or metoclopramide. Can be caused by Chlorpromazine.
