Cranial mononeuropathy VI   

Overview | Symptoms | Treatment | Prevention

Alternative names:

Abducens palsy; Lateral rectus palsy

Definition:

Cranial mononeuropathy VI is a disorder resulting in double vision associated with dysfunction of cranial nerve VI which is responsible for moving the eye laterally.

Causes and Risks

Cranial mononeuropathy VI is a mononeuropathy (damage to a single nerve) involving the sixth cranial (abducens) nerve, one of the cranial nerves that controls eye movement.

Damage to the abducens that occurs by itself is usually associated with diabetic neuropathy, tumors affecting the nerve, or increased intracranial pressure (pressure within the skull).

Abducens dysfunction may be associated with mononeuritis multiplex, or may occur (along with third and fourth cranial nerve dysfunction) because of lesions along their common pathways through the skull.

Trauma, infarction (tissue damage from loss of blood flow) or certain cranial aneurysms may damage the abducens nerve. In some cases, no cause can be found.
