Abstract
AIM:To investigate the efficacy of adjustable suture on partial accommodative esotropia surgery in children. <br> 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. <br> 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). <br> CONCLUSION: Adjustable suture perform operations can one-off correct partial accommodative esotropia more accurately, decrease the frequency of deficient correction and excessive correction efficiently.关键词
