This article evaluated the effect of myopia on the position of the ora serrata relative to the extraocular muscle insertions. In this prospective case series, 11 patients were evaluated during scleral buckling procedures. Intraoperative measurements of the distance from the ora serrata to the muscle insertion in each quadrant were compared to baseline refractive error. The distance between the ora serrata and the muscle insertion increased with increasing myopia superonasally and inferonasally. The surgeon must be aware of the need to position a scleral buckle more posteriorly with increasing myopia to avoid improper scleral buckling position and consequent surgical failure.
本文评估了近视对锯齿缘相对于眼外肌附着点位置的影响。在这个前瞻性病例系列中，对11例患者在巩膜扣带手术过程中进行了评估。将术中测量的每个象限中锯齿缘到肌肉附着点的距离与基线屈光不正进行比较。锯齿缘与肌肉附着点之间的距离在鼻上象限和鼻下象限随近视度数增加而增大。外科医生必须意识到，随着近视度数增加，需要将巩膜扣带放置得更靠后，以避免巩膜扣带位置不当及随之而来的手术失败。
