Abstract
BACKGROUND: Strabismus can have a great negative impact on the quality of life and the well-being of affected patients. In the past, these aspects were often neglected and, compared with somatic functioning, placed in the background. The aim of our study is to elicit factors influencing satisfaction with strabismus surgery, quality of life and expectations of surgery in order to better predict who will benefit the most and who may need further support. METHODS: We made a selection of suitable questionnaires to assess psychosocial aspects of strabismus and decided for Adult Strabismus 20 Questionnaire, Amblyopia and Strabismus Questionnaire, Diplopia Questionnaire, Expectations of Strabismus Surgery Questionnaire and Hospital Anxiety and Depression Scale. We then translated these measures (if not available in German). The patients filled out these forms as part of their preoperative orthoptic and ophthalmological assessment as well as approximately 3 months after strabismus surgery. RESULTS: We enrolled 59 patients in this study. Postoperative strabismus-related quality of life was higher after surgery and anxiety and depression levels were lower. Satisfaction with surgery was lower with higher postoperative angle and diplopia; the latter was also a determinant of lower postoperative quality of life. Higher expectations of strabismus surgery were present with higher depression levels and higher preoperative strabismus angle. CONCLUSION: Our data indicate that strabismus surgery may cause a significant improvement in several psychosocial domains. There is evidence that psychosocial factors can have significant impact on expectations with surgery. Hence, it is important to consider mental health aspects of this disease in order to treat patients in the best possible way.
