摘　　要：目的介绍肌腱松切术合并拮抗肌线状圈套折叠术矫正共同性斜视。方法肌腱松切术在肌止端后５－６ｍｍ处用剪刀从中央向两侧肌缘斜形切开（切开８０％，留两侧肌缘）肌止端斜形切开８０％。拮抗肌线状圈套折叠用０／３号丝线从肌止端中央穿入，另端由肌止端后８－１４ｍｍ处穿出（根据折叠量而定）圈套中央肌肉１－２ｍｍ。结果内斜视３０例，良好率８２％，外斜视３０例，良好率为８３％。肌腱松切术的效果与内直肌后徙５ｍｍ，外直肌后徙８ｍｍ或肌肉边缘切开术的效果相似，联合拮抗肌线状圈套折叠术效果更为可靠。结论此法操作简便，不易引起眼位垂直性偏斜，不易撕裂肌纤维，联合其它肌肉手术时不影响眼前节的血液供应。AbstractObjecfive To introduce the strabismus surgery by means of relaxation myotomy combined with antagonist linear-cycloid tucking.Method The relaxation myotomy is performed 5-6mm away from the muscle insertion point.We the 80% of the central part of the muscle there,then we cut cut 80% of the bilateral margine near the insertion point. The antagonist linear-cycloid tucking is performed by 3-0 thread through the conter of the muscle insertion point,then go out 8-12mm away from the muscle insertion point,(It depends on the decision of the surgery)the cycloid muscle inuolved is 1-2mm.Result In 30 cases of esotropia the success rate is 82%,In 30 cases of exotropia the success rate is 83%.The effect of myotomy is equal to that of medial rectus muscles′recession of 5mm and laterall rectus muscles′recession of 8mm and also equal to the effect of marginal myotomy.The effect is more reliable if combined with antagonist linear-cycloid tucking.Conclusion The advantages of this surgery are technically simple,less possible to cause vertical strabismus.It doesn′t tear the muscle fiber and doesn′t affect the blood supply to the anterior segment of the eyeball when performed with other extraocular muscles.
