Botox has its effects directly on the muscle into which it is injected. Its effects only last about three months. In strabismus, the goal is to weaken the affected muscle on one side of the eye so that the muscle on the opposite side of the eye can work better.
How long will the effects of treatment last? The Botox effect continues typically for 4 months. Studies by Carruthers & al (March 2001) show that most practitioners would recommend an initial course of Botox treatments every 4 months for the 1 year.
