This a retrospective review of medical records from Korea between January 2003 and January 2012 in the Samsung Medical Centre. The long-term outcomes and risk factors for recurrence after unilateral lateral rectus (LR) recession (ULR) in children with small to moderated angle of intermittent exotropia (IXT) were analysed. A total of 214 patients were included in the study. At two years review and at final examination at a mean follow-up of 3.9 years, success rates of 92.5% and 83.2% were achieved respectively. Preoperative exodeviation of 20-24PD was the significant factor for recurrence according to univariable (OR=3.577, p=0.022) and multivariable analysis (OR=3.265, p= 0.034) The authors stated that the limitations are the retrospective nature of the study, no routine data on postoperative sensory status evaluated and other potential risk factors for recurrence were not measured, i.e. amblyopia, lateral incomitance A and V pattern strabismus. They concluded that the overall long-term outcome of ULR for 15-19 PD of IXT achieved the best results in this long-term study.
