Patients with blepharospasm are generally referred to ophthalmologists or neurologists for treatment. A generally accepted standard of care for blepharospasm in people 12 years and older is treatment with BOTOX® (onabotulinumtoxinA) neurotoxin. BOTOX® therapy inhibits the release of a neurotransmitter, acetylcholine, from nerve cells, blocking the signals that promote muscle contraction. The effect is temporary and the treatment can be readministered approximately every three months depending on the individual patient. If a functionally impaired patient does not respond to less invasive treatments, surgical therapy to remove some or all of the muscles responsible for eyelid closure (a procedure called protractor myectomy) may be recommended. If you suffer from blepharospasm, talk to your eye care professional about treatment options.
