“Min_Max_Diff” of the strabismus angle was defined as the difference between “Max angle” and “Min angle.” In addition to the clear reduction of the mean strabismus, also the difference between the maximum and minimum strabismus angle decreases. All these decreases were highly significant (p<0.01). | ||||
