Essential blepharospasm is an idiopathic disorder characterized by involuntary spasm of the eyelids and sometimes other facial muscles. Most patients also have dry, irritated eyes and in most patients, symptoms are worse when exposed to sunlight or bright lights indoors.
Botox injections are the initial treatment for blepharospasm, and this treatment is covered by insurance, since it is a functional issue. Some patients’ symptoms cannot be controlled with Botox alone. For this group of patients, Myectomy surgery is next line of treatment for them. You can consult Dr. Lin Yang for further details regarding Botox treatment or Myectomy surgery for blepharospasm
