What is a common treatment for BEB?

• A. Botulinum toxin injections
• B. Antibiotic drops
• C. Corticosteroid ointment
• D. Laser ablation

Answer: (A)

Blepharospasm, or involuntary eyelid spasms, is best managed with botulinum toxin injections into the eyelid muscles. This toxin blocks acetylcholine release at the neuromuscular junction, weakening the overactive orbicularis oculi and reducing the frequency and intensity of eyelid closing. The effect relaxes the muscles for several months, after which injections can be repeated as the spasm returns. This approach is the standard, most effective, and minimally invasive treatment for BEB.

Antibiotic drops target infection or inflammation rather than muscle overactivity, so they don’t relieve the dystonia. Corticosteroid ointment is used for inflammatory conditions, not for motor control issues. Laser ablation addresses tissue removal and is not a treatment for dystonia.
