METHODS： The records of 216 patients （432 eyes） with lET who underwent surgery, from 2010 to 2015 were studied. Patients with lET whose deviation appeared before 6mo of age and had stable preoperative deviation in two examinations with at least 2wk apart and a minimum 3too postoperative follow up were included. Cases with early onset accommodative esotropia, congenital cataract, retinopathy of prematurity （ROP）, manifest nystagmus, fundus lesions, neurologic and ophthalmic anomalies, 6th nerve palsy and Duane＇s syndrome were excluded. Preoperative abduction deficit was considered from -1 to -3 grading scale. Three months after surgery, children were classified into no-need reoperation [deviation〈15 prism diopters （PD）], and need-reoperation groups （deviaUon〉15 PD）. RESULTS： In this retrospective study, 117 female and 99 male patients with the mean surgical age of 4.7±6.4y were included. Reoperation rate was 33.3% and 16.0% in lET patients with and without abduction deficit, respectively in patients who had a history of late surgery. Abduction deficit increased the odds of reoperation by 82% [OR=1.82, 95% confidence interval （CI） =1.05 to 3.19, P=0.003] in patients who had a history of late surgery （〉2 years old, P=0.021）. Abduction deficit was improved significantly after operation （P〈0.001）. CONCLUSION： Based on our results, abduction deficit can be considered as a risk factor of reoperation in lET patients who are operated at the age of more than 2y.展开更多
