Five patients underwent a muscle union procedure with medial rectus recession. The mean preoperative esotropia in the primary position was 51.0 ± 20.1 prism diopters [PD] (range: 20 to 75 PD). The mean follow-up period was 6.2 ± 2.1 months (range: 3 to 8 months). The mean decrease in esotropia in the primary position was 49.0 ± 18.0 PD (range: 18 PD to 63 PD). The mean postoperative angle in the primary position was 1.6 ± 5.9 PD esotropia (range: 2 PD exotropia to 12 PD esotropia). There was no change in vertical deviation. Satisfactory ocular alignment was achieved using the loop muscle union procedure with weakening of the antagonist muscle. This could be considered an option for a transposition procedures in patients with abducens palsy who have a large-angle esotropia or significant residual deviation after conventional surgery.
5例患者接受了内直肌后徙联合肌肉联合手术。原在位平均术前内斜视度数为51.0±20.1棱镜度[PD]（范围：20至75 PD）。平均随访期为6.2±2.1个月（范围：3至8个月）。原在位内斜视平均度数降低49.0±18.0 PD（范围：18 PD至63 PD）。术后原在位平均斜视角为1.6±5.9 PD内斜视（范围：2 PD外斜视至12 PD内斜视）。垂直斜视无变化。采用对抗肌减弱的环形肌肉联合手术可实现满意的眼位矫正。对于外展神经麻痹且伴有大角度内斜视或传统手术后有明显残余斜视的患者，这可被视为一种转位手术的选择。
