方法：选择30例部分调节性内斜视患儿行双眼内直肌后徙联合调整缝线手术。患儿术前为中度远视，且术前配戴足度镜矫正屈光不正>6mo，非调节部分的斜视度稳定在+20^△～+35^△范围内。术中双内直肌后退3～5mm，保留1～2mm缝线调整量，术后第1d根据眼位调整缝线。术后1wk； 1，3，6，12mo随访，观察眼位、残余斜视度和视功能情况。

结果：术后第1d缝线原位眼位即达正位22例，6例过矫，2例欠矫，正位率为73%。经过缝线调整，正位率达到100%。术后1wk； 1，3，6，12mo残余视近斜视度分别为+5.9^△±2.8^△，+4.4^△±4.3^△，+3.8^△±3.6^△，+2.9^△±3.5^△，+2.7^△±4.1^△，视远斜视度分别为+5.6^△±3.2^△，+4.0^△±3.1^△，+3.4^△±3.4^△，+2.5^△±3.4^△，+2.3^△±3.9^△。术后1，6，12mo分别与术后1wk比较，差异均无统计学意义(P>0.05)。术前有双眼单视功能者13例(43%)，术后有双眼单视功能者23例(77%)，差异有统计学意义(P<0.05)。

结论：调整缝线的手术方式可以更准确的一次性矫正部分调节性内斜视，有效的减少术后过矫或欠矫问题。

METHODS: Thirty children with partial accommodative esotropia were treated by the recession of binocular medial rectus combined adjustable suture. The inclusion criteria were medium hypermetropia, and having wear sufficient degree mirror no less than six months, residual nonaccommodative esotropia deviation of +20^△ ～ +35^△. 3mm to 5mm recession of binocular medial rectus and 1mm to 2mm adjustable suture were kept in surgery. Suture was adjusted on the first day after surgery. The use of adjustable suture after surgery, deviation after surgery and binocular vision function were used to evaluate the efficacy during the follow up.

RESULTS: Twenty-two children(73%)were within orthotropia, 6 children deficient correction and 2 children excessive correction. After adjustment, all children(100%)were within orthotropia. Residual strabismus degrees for 33cm and 6m were +5.9^△±2.8^△, +4.4^△±4.3^△, +3.8^△±3.6^△, +2.9^△±3.5^△, +2.7^△±4.1^△ and +5.6^△±3.2^△, +4.0^△±3.1^△, +3.4^△±3.4^△, +2.5^△±3.4^△, +2.3^△±3.9^△ 1-week, 1-month, 3-month, 6-month, 1-year after surgery respectively, without significant difference(P>0.05). Thirteen children(43%)before surgery and 23 children(77%)after surgery had binocular vision, with significant difference(P<0.05).

CONCLUSION: Adjustable suture perform operations can one-off correct partial accommodative esotropia more accurately, decrease the frequency of deficient correction and excessive correction efficiently.
