The authors aimed to evaluate the relationship between family history and deviation control in intermittent exotropia, and the effects of age, sex, angle and refractive status on deviation control. This was retrospective review of 54 patients aged 7.7 ±4 years (21 male, 33 female). Fourteen patients had family history of exotropia. There was a mild correlation between age and total exotropia control score, and age with near exotropia control score. The angle at near fixation had a significant moderate correlation between total exotropia and near exotropia control scores. The angle at distance fixation had a mild correlation with distance exotropia control score and total exotropia control score. The only significant finding was the angle at distance as an independent predictor for complete deviation control. The authors conclude a high angle of deviation correlates positively with poor deviation control.
