Eyelid botulinum toxin injections for the dry eye.
The injection of botulinum toxin into the medial lower eyelid causes a local paralysis of the orbicularis oculi muscle. The paralysis leads to a decreased action of the lacrimal pump and an improved lubrication of the ocular surface. The injection reduces the discomfort in eyes of patients with Sjögren's syndrome.
