We had a journal club April 29, 2015 where we reviewed the Pediatric Eye Disease Investigator Group study on patching for intermittent exotropia vs observation.  The bottom line is patching is only 5% better at reducing deteroriation than observation alone after 6 months. Most of the kids remained stable and some did improve but no difference in improvement between groups.  I haven’t been excited about prescribing patching for intermittent exotropia since that paper came out. The Peds team isn’t either now.
