The purpose of our study is to determine the motor and sensory outcomes in children undergoing surgery for infantile exotropia after age of 2 years and to review the association of pre-operative variables with surgical outcomes. In this retrospective study, we included patients who were diagnosed as infantile exotropia with a deviation of > 25 Prism diopters (PD) before 12 months age and subsequently underwent strabismus surgery at a single centre from 2014 to 2019. Postoperative motor alignment was assessed at 6 weeks and binocular sensory status was assessed using Worth 4-Dot (WFDT) and Titmus stereoacuity tests at 6 months follow up. A total of 30 patients were analysed. At 6 weeks post-op, motor success was seen in 24 patients (80%), whereas 6 patients (20%) constituted failure group which included 5 patients (17%) with a recurrence and 1 (3%) with an overcorrection. At 6 months post-op, measurable stereopsis was present in 15 patients (50%) with a stereopsis better than 400 sec of arc in 12 patients (40%), binocular single vision was present in 6 patients (20%) on WFDT. Smaller pre-operative angle of deviation was significantly associated with motor success for distance (p = 0.009) and near (p = 0.020). Smaller pre-operative angle for distance was associated with better sensory outcomes (p = 0.041). Pre-operative vision, age at surgery and duration of misalignment did not show statistically significant association with motor and sensory outcomes. Thus we conclude, smaller pre-operative angle of deviation for distance and near are associated with good motor and sensory outcomes. Older age at surgery in this study had outcomes comparable to younger age group reported in previous studies. The association of surgical outcomes with pre-operative vision and duration of misalignment could not be proven by this study.
