内直肌悬挂后退术常用来调节斜视手术量,或用于分离性垂直性斜视。作者以它作为常规手术方法,对31例内斜视患儿进行矫正。作者根据内斜视程度计算手术后退量,计算方法与传统后退术相同。将悬吊线置于内直肌原附着处的中央部。双臂缝线穿过巩膜的长度为2.0mm,进针处针距为3.0mm,出针处针距为1.0mm,这样双臂线会聚成V形,尖向角膜。将此双臂悬吊线向前拉紧,把内直肌拉到原附着处,用两脚规测量线的长度,即将其一脚顶住内宜肌原附着处前沿缝线穿出处,另一
Rectus muscle retraction is often used to adjust the amount of strabismus surgery, or for the separation of vertical strabismus. The authors used it as a routine surgical method, 31 cases of esotropia in children correction. The author calculates the amount of surgical backsteps based on the degree of esotropia, and the calculation method is the same as that of conventional backstroke. The suspension line placed in the central rectus muscle attached to the central part. The length of the suture through the sclera is 2.0 mm, the needle pitch at the needle is 3.0 mm, the needle pitch at the needle is 1.0 mm, so that the arm lines converge into a V-shape and point to the cornea. The arms hanging from the line forward tension, the inner straight muscle pulled to the original attachment, measuring the length of the line with the two-legged gauge, that is, one foot to withstand the front of the myofibril attachment front suture piercing out, another
