Summary
Benign essential blepharospasm (BEB) is a functionally disabling focal dystonia. Botulinum neurotoxin (BoNT) therapy is suboptimal in many BEB patients. Repetitious transcranial magnetic stimulation (rTMS) therapy is a promising noninvasive therapy and has shown positive benefits in BEB. rTMS therapy can be easily combined with BoNT injections to enhance the effects of BoNT in BEB.
