The full name of the disease is blepharospasm-mandibular dystonia syndrome. In the early stages of the disease, only the eye muscles are involved, with involuntary blinking as the main manifestation, and in severe cases, even persistent contraction of the eyelid muscles, resulting in the inability to open the eyes and functional blindness. As the symptoms progress and expand, they may involve the mouth and jaw, resulting in dystonia of the mouth and jaw. The cause of the disease is not fully understood, and treatment can begin with symptomatic treatment with medications to reduce symptoms, such as thiopride, carbamazepine, or clonidine. If medication is not effective, Botox can also be used as a local injection, but when injected in the eyelid it can easily cause the side effect of ptosis and requires good control of the dose and the site of the injection.
