Cranial mononeuropathy III - diabetic type -- is a mononeuropathy. This means that only one nerve is damaged. The condition affects the third cranial (oculomotor) nerve. This is one of the cranial nerves that control eye movement.
This type of damage may occur along with diabetic peripheral neuropathy. Cranial mononeuropathy III is the most common cranial nerve disorder in people with diabetes. It is due to damage to the small blood vessels that feed the nerve.
Other causes may include:
Infarction of the nerve (tissue damage from loss of blood flow)
