I am 39 years old and was just diagnosed a month ago, I don't have a severe case but bad enough to be diagnosed and unable to have prisms made. I never had it during my childhood. Spoke to a surgeon who performs the surgery and also has done years of research on children using botox to help them strengthen their weak muscle while paralyzing their strong muscle and allowing the weak muscle to strengthen. I go back to the eye surgeon and am going to schedule my surgery to align my eye, as an almost 40 year old woman I will be so happy to be able to use both of my eyes to see out of at once.
