I need an ophthalmologist in Los Angeles that specializes in Botox treatments for strabismus, any suggestions?

Guy Massry, MD of Beverly Hills, CA might.  He is an oculoplastics specialist.  If he does not do it, he would likely know who does in that area.

A colleague of mine who practices in Torrance, CA , Lydia Matkovich, MD likely would do it well.  She did fellowship training in both pediatric ophthalmology/strabismus and glaucoma....and in Residency training she was under the tutelage of John Holds, MD (oculoplastics doc), who learned Botox injections under the second-most experienced person in the world with Botox: Richard Anderson, MD.
Another friend, Guy Massry, MD of Beverly Hills, CA might.  He is an oculoplastics specialist.  If he does not do it, he would likely know who does in that area.
I hope that either can help you.  Alternatively, you could likely be helped at the Jules Stein Eye Institute.
