To determine the effect of botulinum toxin injection in the eyelid on lacrimal film in patients with facial dystonia.Twenty-four patients with essential blepharospasm and hemifacial spasm were submitted to botulinum toxin injection and lacrimal film tests were performed before the application and after seven and thirty days.There was improvement in symptoms of dry eye and rose bengal test, however, the breakup time and Schirmer's test did not show significant variation between pretreatment and after 1 month of follow-up.The dry eye symptoms in patients with facial dystonia may be attenuated by botulinum toxin due to its possible inhibitory effect on the orbicular muscle leading to a decrease in lacrimal pump. |
