Cranial mononeuropathy VI is a damage to the sixth cranial (skull) nerve. This nerve, also called the abducens nerve, helps controls eye movement. Abducens nerve disorders are often associated with diabetic neuropathy, trauma, infections (such as meningitis or sinusitis), infarction (tissue damage from loss of blood flow), brain aneurysms, tumors, or increased intracranial pressure (pressure within the skull). In some cases, no cause can be found. Because their are common nerve pathways through the skull, other cranial nerves (such as the third or fourth cranial nerve) may be also affected.
