PURPOSE To establish whether clinical factors were correlated with deviation control in intermittent exotropia. METHODS This retrospective study included 54 patients with intermittent exotropia. The patient's sex, family history, age at first admission, best corrected visual acuity, refractive errors after cycloplegia, angles of ocular deviation at near and distance, and near, distance, and total deviation control were evaluated. Ocular deviation controls were determined according to the Mayo Clinic's office-based scale. Correlation analysis was performed between the deviation control and the determined clinical factors. RESULTS Spearman correlation analyses revealed a mild correlation between age with total exotropia control score and age with the control of near exotropia control score (r = 0.320, P = .018 and r = 0.339, P = .012, respectively). The angle of deviation at near showed a significant moderate correlation between total exotropia control score and near exotropia control score (r = 0.523, P < .001 and r = 0.780, P < .001, respectively). The deviation angle at distance showed a mild correlation with distance exotropia control score and total exotropia control score (r = 0.423, P = .001 and r = 0.288, P = .034, respectively). The angle of deviation at distance showed a mild correlation with the angle of deviation at near (r = 0.359, P = .008). The deviation angle at distance was established as an independent factor for predicting total exotropia score (P = .037, P = .015, respectively). CONCLUSIONS The high deviation angle correlates positively with poor deviation control. The distance deviation angle is an independent predictor of total deviation control for the first time in the literature. [J Pediatr Ophthalmol Strabismus. 20XX;XX(X):XX-XX.].
