A study reported in the Journal of American Association for Pediatric Ophthalmology and Strabismus suggests that surgery to correct strabismus not be limited to children. Adults as old as 90 can benefit from surgical correction of strabismus. In the study, the participants answered questions on how strabismus affected their lives before they had surgery and again after they underwent surgical correction. Researchers looked at areas such as its effects on social interaction (maintaining eye contact), concerns about the future (blindness, inability to work/read) and job related concerns (not being hired, retained and/or promoted). In all areas, participants reported a significant improvement after surgery.
