Traumatic disinsertion of an inferior rectus muscle in a 25-year-old man was diagnosed preoperatively by an associated lower lid retraction. This finding is significant in differentiating a traumatic disinsertion of the inferior rectus from an inferior rectus palsy secondary to an orbital floor fracture. Associated findings include ipsilateral hypertropia, impaired depression of the affected eye in abduction, the formation of a sulcus in the lower lid on attempted downgaze, negative forced duction testing, and positive forced muscle generation.
一名25岁男性下直肌创伤性断离在术前通过相关的下睑退缩得以诊断。这一发现对于区分下直肌创伤性断离与眶底骨折继发的下直肌麻痹具有重要意义。相关表现包括同侧上斜视、外展时患眼下转受限、试图向下注视时下睑沟形成、被动牵拉试验阴性以及主动收缩试验阳性。
