[Evalution of life quality of children with intermittent exotropia one year after the effective surgical treatment].

Objective: To investigate the changes of life quality in children with intermittent exotropia (IXT) and their parents 1 year after surgical treatment. Methods: Retrospective study. The scores of Chinese version of the intermittent exotropia questionnaire (CIXTQ) and follow-up visits at 1 week preoperatively and 3 months, 12 months postoperatively were collected from 122 IXT children with successful eye positions 3 months postoperatively and their parents in Department of Ophthalmology, the First Affiliated Hospital of Nanjing Medical University from December 2015 to July 2016. The CIXTQ scores of children with different eye positions 1 year postoperatively, the impact of parent CIXTQ scores and 1-year postoperative eye positions on children's CIXTQ scores and parents' proxy CIXTQ scores, were analyzed. Repeated measures anova was used for the analysis. Results: A total of 122 IXT children were collected in this study, there were 64 boys and 58 girls, age (2-15) years, mean (7±3) year. The eye positions of 88 (72.1%) children were successful 1 year postoperatively, and 34 (27.9%) were undercorrected 1 year postoperatively. The CIXTQ scores of children with different eye positions 1 year postoperatively were significantly higher than that at 1 week preoperatively and at 3 months postoperatively(scores of all children, 83.27±9.49 vs . 57.30±8.37 and 69.19±7.95; successful children, 84.12±8.80 vs . 57.36±8.16 and 69.99±7.85; undercorrected children, 81.07±10.95 vs . 57.14±9.04 and 67.10±7.98), with statistical significance (compared with 1 week preoperatively, t= 22.44, 22.13, 8.73; compared with 3 months postoperatively, t= 12.42, 11.40, 5.49; all P< 0.001). However, the parent' CIXTQ scores of children with recurrent strabismus showed no significant differences when compared to those at 3 months postoperatively ( P> 0.05). The CIXTQ scores of parents and eye positions 1 year postoperatively showed no impact on children's CIXTQ and parents' proxy CIXTQ scores (all P> 0.05). Conclusion: The orthodontic surgery can effectively improve the life quality of children with IXT and their parents 1 year after surgical treatment, and there is no correlation between the life quality of children and their parents.
