Transposition of vertical muscles for residual tropia was performed: nasal displacement for exotropia and temporal displacement for esotropia. Five millimeter equal displacement of superior and inferior recti corrected 10 to 14 prism diopter while equal displacement of 7 to 8 mm resulted in correction of 25 prism diopter. Special indications of this procedure may be: (1) residual tropia in cases with severe intractable ambylopia or pathology in one eye where patient and surgeon may be reluctant to operate on the sound eye, or (2) residual tropias of the alternating type in patients who underwent operations in all horizontal muscles of both eyes.
外斜视采用鼻侧移位，内斜视采用颞侧移位。上直肌和下直肌等量移位5毫米可矫正10至14棱镜度，而等量移位7至8毫米则可矫正25棱镜度。该手术的特殊适应证可能为：（1）患有严重难治性弱视或单眼病变的病例中的残余斜视，此时患者和外科医生可能不愿对健眼进行手术；或（2）双眼所有水平肌均接受手术的患者中的交替性残余斜视。
