Abstract
Purpose: Blepharospasm is a condition characterized by abnormal contractions or twitching of the eyelid due to excessive contractions of the orbicular muscle. The purpose of the present study was to clarify the prevalence and severity of blepharospasm in end-term cancer patients and to clarify the correlation between agonal facies and angor animi or blepharospasm. Method: Diagnoses were made using the Wakakura method and the nictitating stress test, and the severity of the condition was evaluated on the basis of a palpebral dystonia grade classification system. In this positive observational study, all patients were hospitalized in our institution between October and December 2010. Result: Of the 51 evaluations, 19 (37.3%) were diagnosed with blepharospasm, and the severity of nine was ≥3 according to a five-point grading scale. Many cases were treated using antipsychotics or benzodiazepine, and an improvement was observed in all the seven cases that had medication adjustments. Diagnostically, there was no correlation between glabellar lines and pain. Agonal facies in end-term cancer patients included elements of blepharospasm in addition to angor animi. Conolusion: Blepharospasm frequently occurred in patients admitted in the palliative care unit, and it decreased their quality of life. It is important to evaluate this condition and to consider medication adjustments.
