Lower-eyelid tarsal ectropion is an unusual form of eyelid malposition in which the entire lid is everted. The cause is most likely the disinsertion of the lower-eyelid retractors. In 12 eyelids of six patients, a transconjunctival approach was used to reunite the retractors with the inferior tarsal border. In eight eyelids, a horizontal tightening procedure was also needed. The looping passage of fornix sutures through the full thickness of the eyelid created a vector force that helped rotate the lid margin inward. The subsequent formation of an inflammatory cicatrix induced by the absorbable sutures also contributed to maintain the lid in an upright posture. During follow-up periods ranging from 8 to 36 months, there were no instances of overinversion, recurrent ectropion, or suture abscess.
下睑睑板外翻是一种不常见的眼睑位置异常形式，即整个眼睑向外翻转。其原因很可能是下睑缩肌的附着中断。在6例患者的12只眼睑中，采用经结膜入路使缩肌与下睑板边缘重新连接。在8只眼睑中，还需要进行水平收紧手术。穹窿缝线在眼睑全层的环形穿过产生了一个向量力，有助于使睑缘向内旋转。可吸收缝线诱导形成的炎性瘢痕也有助于使眼睑保持直立姿势。在8至36个月的随访期内，未出现睑内翻过度、复发性外翻或缝线脓肿的情况。
