Tardive blepharospasm is defined as the presence of repetitive sustained contractions of the orbicularis oculi that have lasted for at least 1 month and that developed during or within 3 months of the discontinuance of treatment with dopamine antagonists (in the absence of other disease or familial causes). Symptoms of tardive blepharospasm fluctuate. Fatigue, anxiety, work, and light exacerbate tardive blepharospasm, whereas rest and sleep relieve it.
