Blepharospasm / Hemi Facial Spasm
Blepharospasm and facial spasm are both local dystopias of the face, that is an involuntary movement of the eyelids / face.
Blepharospasm can vary in severity and affects both eyes. Stress, fatigue and bright lights can worsen blepharospasm. In its most severe form, affected people may be involuntarily squeezing their eyes shut and being unable to open them.
Whilst it is still unknown what exactly causes blepharospasm, certain conditions such as dry eyes or meibomian gland inversion (mild upper lid entropion) can worsen the squeezing / spasms.
Whilst there is no known cure for blepharospasm, the right treatment can be very useful in helping people live with this condition. Botulinum toxin injections (usually required every 3 to 6 months) and sometimes even surgery can be of benefit.
Hemifacial spasm affects one side of the face - sometimes it can start with the eyelids twitching and then gradually start to involve the cheek and even neck on the affected side. In some people, the loop of a blood vessel can push on the facial nerve causing the facial movements, which may be treatable. In many people, botulinum toxin injections are often very helpful in managing this condition.
