    Author: Lyu IJ, Park KA, Oh SY.
    Journal: Br J Ophthalmol; 2016 Oct; 100(10):1433-6. PubMed ID: 26769671.
    Abstract:
    AIM: To evaluate long-term surgical outcomes and risk factors for recurrence after unilateral lateral rectus muscle recession (ULR) in children with small to moderate angle intermittent exotropia (IXT). METHODS: 214 patients with basic type IXT of 15-24 prism dioptres (PD) who underwent ULR were included. The main outcome measure was success rate at 2 years after surgery and at final follow-up. The risk factors related to recurrence were evaluated using univariable and multivariable logistic regression analyses. RESULTS: Success rate at postoperative 2 years was 92.5% and at final examination after a mean follow-up of 3.9 years was 83.2%. No overcorrection was observed. Preoperative exodeviation of 20-24 PD was the significant risk factor for recurrence according to both univariable (OR=3.577, p=0.022) and multivariable analysis (OR=3.265, p=0.034). CONCLUSIONS: The overall long-term successful alignment rate of ULR for 15-24 PD of IXT was good. However, patients with 20-24 PD of IXT showed worse prognosis compared with 15-19 PD of IXT.
