The observation of a reduction in stereoacuity suggests a loss of binocular vision (Westheimer, 1994) and has been thought to indicate the need for surgical intervention (Adams et al., 2008). The management of intermittent exotropia in children is controversial, with the overall success rate of both surgical and nonsurgical treatments typically between 40% and 70% (Richardson and Gnanaraj, 2006). Surgical treatment is usually deferred till school-age years, in part because of the gradual tendency of the strabismus to decompensate in some children over time (Romanchuk et al., 2006), and because younger children are more prone to develop abnormal sensory adaptations and permanent loss of bifixation after surgery especially with overcorrection ER -
