Incomitant vertical strabismus. Treatment with posterior fixation of the inferior rectus muscle
R. A. Saunders
Three patients with evidence of inferior rectus muscle paresis were
surgically treated for diplopia in downgaze following blowout fracture of
the orbit or operative trauma. In each case, surgery involved the placement
of two posterior fixation sutures 13 or 14 mm behind the physiologic
insertion of the inferior rectus muscle in the contralateral eye. In one
case, posterior fixation was combined with a small inferior rectus muscle
recession. All three patients experienced relief of their diplopia and
improvement in their binocular field of vision. There were no untoward
sequelae and no surgically induced changes in primary position alignment.
