Introduction: The evidence base for the treatment of strabismus (squint) is poor. Our main aim is to improve this evidence base for the treatment of a common type of childhood squint {intermittent exotropia. [X(T)]}. We conducted an external pilot study in order to inform the design and conduct of a future full randomised controlled trial (RCT). https://www.spidertattooz.com/WAC-4011-LED-Horizontal-Step-Light-Colorscaping/
