Congenital fibrosis of the extraocular muscles is a rare hereditary strabismus disorder. A case of congenital fibrosis of the inferior rectus muscles with severe chin-up posture and bilateral limitation of up gaze is reported. Bilateral large recessions of the tight inferior rectus muscles provided only partial improvement. Residual head posture and hypotropia were successfully corrected with bilateral horizontal rectus muscle transpositions toward the superior rectus muscles, despite persistently tight inferior rectus muscles at the time of surgery.
先天性眼外肌纤维化是一种罕见的遗传性斜视疾病。本文报告一例先天性下直肌纤维化病例，该患者存在严重的仰头姿势及双侧上视受限。对紧张的双侧下直肌进行大量后徙术仅带来部分改善。尽管手术时双侧下直肌仍持续紧张，但通过将双侧水平直肌向上直肌方向移位，成功矫正了残留的头位姿势和下斜视。
