灰线是众所周知的表面解剖标志，外科医生在修复涉及眼睑边缘的撕裂伤时使用它。据我们所知，之前没有报道过灰线的任何深层或浅层解剖学对应物。我们在灰线定位后对 51 个眼睑的块切除进行了组织学检查。可见的灰线在组织学上一致地对应于轮匝肌的最表层部分，即里奥兰肌肉。我们评论灰线形态随眼睑运动的变化，并提出一个假设来解释其“灰色”颜色。
The gray line is a well-known surface anatomic landmark used by surgeons in the repair of lacerations involving the lid margin. To the best of our knowledge, no description of any deep or superficial anatomic counterpart of the gray line has been previously reported. We examined block resections of 51 eyelids histologically following localization of the gray line. The visualized gray line was consistently seen to correspond histologically to the most superficial portion of the orbicularis muscle, known as the muscle of Riolan. We comment on changes in gray line morphology with lid movement, and we advance a hypothesis to explain its "gray" color.
