Cranial mononeuropathy VI is a nerve disorder. It affects the function of the sixth cranial (skull) nerve. As a result, the person may have double vision.

Cranial mononeuropathy VI is damage to the sixth cranial nerve. This nerve is also called the abducens nerve. It helps you move your eye sideways toward your temple.
Disorders of this nerve can occur with:
- Brain aneurysms
- Nerve damage from diabetes(diabetic neuropathy)
- Gradenigo syndrome (which also causes discharge from the ear and eye pain)
- Tolosa-Hunt syndrome, inflammation of the area behind the eye
- Increased or decreased pressure in the skull
- Infections (such as meningitis or sinusitis)
- Multiple sclerosis (MS), a disease that affects the brain and spinal cord
- Trauma (caused by head injury or accidentally during surgery)
- Tumors around or behind the eye
In some people, there is no clear cause.
Because there are common nerve pathways through the skull, the same disorder that damages the sixth cranial nerve may affect other cranial nerves (such as the third or fourth cranial nerve).
