Abstract
Aim: To investigate the incidence and risk factors for dry eye after pediatric strabismus surgery.
Methods: Children aged 5 to 12 who underwent strabismus surgery were included in this single-center, prospective, cohort study. The ocular surface assessments were conducted 1 day before and 1 week, 4 weeks and 8 weeks after surgery. The main outcome measures are the incidence of dry eye after strabismus surgery and associated risk factors.
Results: A total of 84 eyes (48 children) that underwent strabismus surgery were included in the study. The mean age at surgery was 7.21 years. The incidence of dry eye was 47.62% at 1 week, 10.71% at 4 weeks, 0% at 8 weeks after surgery. The preoperative tear breakup time (BUT) were lower in the dry eye group than that in the non-dry eye group (P<=0.01). The univariate analysis showed that preoperative BUT was significantly associated with the incidence of dry eye after pediatric strabismus surgery (odds ratio [OR]: 0.647, confidence interval [IC]: 0.503~0.833, P<=0.01).
Conclusions: Dry eye commonly occurs after pediatric strabismus surgery. Tear film instability is more common than deficient aqueous tear production in patients with dry eye after surgery. Children with a low preoperative BUT are more likely to develop dry eye after strabismus surgery.
