Impact of strabismus surgery on health-related quality of life in adults.

PURPOSE OF REVIEW: Adult strabismus can cause many symptoms, which have generally been divided into functional complaints and social complaints. The validity of surgical correction has historically been based on the restoration of functional improvement. In the absence of this expectation, surgery was labeled cosmetic. Yet, many studies have revealed the immense impact of ocular misalignment on psychosocial variables. The purpose of this article is to review the potential functional and psychosocial benefits of strabismus surgery and to summarize the development and status of questionnaires to help quantify these benefits. RECENT
FINDINGS: Functional benefits of strabismus surgery have been recently summarized with a meta-analysis. Several questionnaires have been evaluated to assess the functional and psychosocial factors in adult strabismus. Two strabismus-specific questionnaires, the Amblyopia and Strabismus Questionnaire and the Adult Strabismus-20, reveal improvements in adults following surgery. The appropriate patient population, impact of comorbidities on the scores, and the timing of the administration of the questionnaire postoperatively still need to be determined.
SUMMARY: Future studies of the impact of strabismus surgery in adults will need to report not only objective motor results, but also the impact on health-related quality of life to encompass all the benefits of strabismus surgery.
