Paralysis of the abducent nerve causes inward turning of the eye (internal strabismus) leading to double vision.
The abducent nerve is the sixth cranial nerve. All 12 cranial nerves, the abducent nerve included, emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column.
