Apraxia of lid opening is a condition in which patients who have otherwise normal eyelids have difficulty opening the eyelids. This is a problem in the circuitry for opening the eyelids, much like blepharospasm is a problem in the circuitry causing squeezing of the eyelids. Pure apraxia of lid opening (which is not associated with blepharospasm) is very rare. However, apraxia of lid opening is commonly associated with blepharospasm. The specific cause or control center for these disorders is poorly understood, but must be somehow intertwined. A blepharospasm patient with associated apraxia of lid opening will typically have spasms closing the eyelids and then for seconds after the spasm stops, the patient is still unable to open the eyelids
