Preoperative and postoperative data of the patients who underwent the muscle union procedure for paralytic strabismus.

SD = standard deviation; PD = prism diopters.
*Successful alignment was defined as a deviation ≤10 prism diopters.
†Under-correction was defined as a residual deviation more than 10 PD.
‡Overcorrection was defined as an overcorrected deviation more than 10 PD.
aChange in horizontal deviation between postoperative deviation and preoperative deviation.
bChange in the limitation of the horizontal paralytic extraocular muscle between postoperative and preoperative deviation.
Voluntary ductions were performed using a 4-point scale ranging from 0 to -4: 0 = patient has full movement in the affected eye; -2 = patient is unable to move the affected eye past the midline; -3 = patient is unable to move the affected eye to the midline; and -4 = patient has no adducting movement in the affected eye.
