Essential blepharospasm responding to haloperidol.

摘要

SIR: Blepharospasm is a disorder of adulthood that is more common in women. It presents as a sudden involuntary bilateral eye closure that is often exacerbated by air pollution, wind, exposure to bright light, movement, and stress. However, to date it is not possible to correlate it with any psychopathology. If it presents as an isolated blepharospasm in adults, it is better termed as essential blepharospasm. It must be differentiated from Meige's syndrome which includes oromandibu-lar dystonia along with blepharospasm.Below we describe a case of essential blepharospam that responded to low doses of haloperidol but not to other drugs.Case ReportA 32-year-old married man presented with bilateral blepharospasms that lasted for 1 to 2 minutes. The spasms were provoked by light, embarrassment, and fatigue. The spasms would disappear in sleep. These complaintswere of 5-month duration.
