These two muscles are synergists or "yoke muscles" as both attempt to move the eye over to the left or right. Collier, however, was "unable to accept this explanation", his view being that since the sixth nerve emerges straight forward from the brain stem, whereas other cranial nerves emerge obliquely or transversely, it is more liable to the mechanical effects of backward brain stem displacement by intracranial space occupying lesions. Sanders SK, Kawasaki A, Purvin VA. Patients sometimes adopt a face turned towards the side of the affected eye, moving the eye away from the field of action of the affected lateral rectus muscle, with the aim of controlling diplopia and maintaining binocular vision. radial nerve palsy, we treat the nerve injury expectantly if the fracture can be reduced closed. Most patients can be expected to recover in 1 to 4 months. In 3 to 4 weeks, if recovery has not begun, assess the extent of the nerve damage by electromyography.

Copyright 2002 BC Decker). Patients older than 50 years with known vasculopathic risk factors, especially diabetes mellitus, usually can be followed clinically in the absence of other neurological symptoms. It is relatively rare. to wait several months before starting additional treatment. If the palsy worsens, the affected eye may drift toward the midline, even when looking straight ahead. Diplopia is also increased on looking to the affected side and is partly caused by overaction of the medial rectus on the unaffected side as it tries to provide the extra innervation to the affected lateral rectus.
