Abducens Nerve Disorder : How To Remember Easily ?

  • A – Abducens Nerve: The sixth cranial nerve innervates the lateral rectus muscle.
  • B – Brainstem Abducens Palsy: Infarct, tumor, hemorrhage, vascular malformation, and multiple sclerosis are the most common etiologies of brainstem abducens palsy.
  • D – Dorsal Pontine Injury: Foville’s syndrome after dorsal pontine injury includes lateral gaze palsy, ipsilateral facial palsy, and contralateral hemiparesis incurred by damage to descending corticospinal fibers.
  • U – Underlying Causes: Treatment of abducens palsy is aimed at prompt correction of the underlying cause.
  • C – Cavernous Sinus: In the cavernous sinus, the nerve can be affected by carotid aneurysm, carotid cavernous fistula, tumor (pituitary adenoma, meningioma, nasopharyngeal carcinoma), herpes infection, and Tolosa-Hunt syndrome.
  • E – Elevated Intracranial Pressure: Unilateral or bilateral abducens palsy is a classic sign of raised intracranial pressure.
  • N – Nucleus Lesion: A nuclear lesion has different consequences because the abducens nucleus contains interneurons that project via the medial longitudinal fasciculus to the medial rectus subnucleus of the contralateral oculomotor complex.
  • S – Subarachnoid Course: Along its subarachnoid course, the abducens nerve is susceptible to meningitis, tumor, subarachnoid hemorrhage, trauma, and compression by aneurysm or dolichoectatic vessels
