Paresis and restriction of the inferior rectus muscle after orbital floor fracture.
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.
