Treatment of Blepharospasm
Sometimes, symptoms of blepharospasm are relieved by sleep, relaxation, gazing downwards, artificial tears, traction on eyelids, talking, humming or singing. Other times, more intervention is necessary.
At Idaho Eyelid and Facial Plastic Surgery, we have a number of options to treat blepharospasm, including Botox and Dysport injections. Botulinum toxin injections work by disrupting the communication between nerve and muscle, thereby relaxing the overactive muscles that cause blepharospasm. Botulinum toxin acts by blocking neural transmission at four different sites in the body – the neuromuscular junction, autonomic ganglia, postganglionic parasympathetic nerve endings and postganglionic sympathetic nerve endings, all of which release the neurotransmitter acetylcholine. It irreversibly blocks the release of acetylcholine, the principal neurotransmitter at the neuromuscular junction, without causing degeneration of the nerve terminals.
