Botulinum toxin application for spasm or eye tic

The spasm or tic in the eye is the involuntary and continuous contraction of the orbicular muscle that surrounds the eyes, produces a closing of the eyelids; in some cases unleashed by situations of anxiety or stress, or fatigue. The injection of botox in the muscle produces a relaxation of the same and a disappearance of the tic; in some cases it is not necessary to repeat the botox application indefinitely since the tic can be definitively corrected. When the patient is several months without performing the tic, the brain assimilates it and the involuntary contraction that in the end is a stimulus that sends the brain disappears.
