Measuring health-related quality of life in individuals with cyclodeviation using the Adult Strabismus 20 (AS-20) questionnaire.

To assess health-related quality of life (HRQoL) in patients diagnosed with cyclodeviation and to evaluate subjective change following surgical treatment using the Adult Strabismus-20 (AS-20) questionnaire. A prospective cohort study was performed from 2014 to 2019 on 29 adult patients with cyclodeviation and cyclodiplopia who were due to undergo corrective strabismus surgery by the same surgeon. The group was divided into two subgroups, according to the type of surgery required for fusion. All scores were analyzed for the whole sample and subgroups. Preoperative scores were compared with those of control patients. Pre- and postoperative QoL scores were successfully collected from 26 patients (mean age, 56 years; 8 female) using the AS-20 questionnaire. Scores were significantly higher for control subjects than for patients in the cyclodeviation group (P = 0.0001). Postoperative scores for all 20 questionnaire questions were significantly improved for all patients (P = 0.002). There was a significant improvement in the functional subscale score (P = 0.001), but not in the psychosocial subscale score (P = 0.23). Results were enhanced by Rasch analysis. Cyclodeviation patients demonstrated significantly lower scores than controls. The functional scores were significantly lower than the psychosocial scores, in contrast to other forms of strabismus. Strabismus surgery had a significant effect on quality-of-life scores in this group of adults.
