Blepharospams treated with eyelid suspension: long terme follow up and outcomes

Purpose Blepharospasm is defined as a located form of dystonia which is best medically treated with botulinum toxin injections. Methods Our study concerned patients suffering from blepharospasm and operated of eyelid suspension because of botulinum toxin insufficiency, and their follow up over many years. Results The mean time between blepharospasm diagnostic and surgery was 43.8 months. 76% of patients needed new toxin injections after a mean time of 3.5 months after surgery. A new surgery was performed because of late overcorrection for 28% of patients, with a mean time between the two surgeries of 64 months. Compared with previous studies, our patients population was similar, the patient rate retreated with toxin was high but lower than the 100% generally described. The long terme re‐operation rate was high in our study. This over‐correction could be linked to a blepharospam decreasing intensity after a many years evolution. Conclusions Most patients operated of eyelid suspension for blepharospasm need new botulinum toxin injections but some can be over‐corrected in case of pathology relief after many years of progression.
