Bupivacaine Injection of Eye Muscles to Treat Strabismus

Summary

This study seeks to determine if bupivacaine injection of eye muscles can make them stronger and stiffer, and thereby correct the position of eyes that are turned in or mis-aligned, a condition generally termed strabismus. It seeks further to find out the different effects of various concentrations or formulations of bupivacaine, and whether addition of Botox to other eye muscles can add to the effect of bupivacaine and enhance the correction of strabismus.
