Six patients had both restriction and paresis of the inferior rectus muscle after blowout fracture of the inferior orbital floor. All six were orthophoric in the primary position but had a severely constricted field of single binocular vision with troublesome diplopia on upgaze and downgaze. Recessing both the inferior rectus muscle and the superior rectus muscle in the injured eye greatly increased the field of single binocular vision. The symptoms improved in all six cases.
6例患者在眶下壁爆裂性骨折后出现下直肌受限和麻痹。所有6例患者在第一眼位均为正视，但单眼双眼视觉范围严重受限，上视和下视时出现明显复视。对患眼下直肌和上直肌进行后徙术，可显著扩大单眼双眼视觉范围。6例患者的症状均有改善。
