A case of lid retraction following blow-out fracture of the orbit with enophthalmos is reported. This paradoxical complication has been described previously in only two cases, both by the same authors. It has been hypothesized that the lid retraction is secondary to Mueller's muscle overaction; however, excision of Mueller's muscle had no effect in this case. A new hypothesis is presented that this condition may be due to traction on the connective tissue sheath of the levator palpebrae muscle through its interconnections with the connective tissue systems of the other extraocular muscles.
报告了一例眼眶爆裂性骨折伴眼球内陷后出现睑裂退缩的病例。这种矛盾的并发症此前仅在两例病例中被描述过，且均由同一组作者报道。据推测，睑裂退缩继发于米勒肌过度活动；然而，在该病例中切除米勒肌并无效果。本文提出了一种新的假说，即这种情况可能是由于提上睑肌的结缔组织鞘通过与其他眼外肌的结缔组织系统相互连接而受到牵拉所致。
