Cranial mononeuropathy most often involves cranial nerves (CN) III, IV, VI, VII, or II. Disease of CN III, IV, and VI manifests as acute or subacute periorbital pain or headache followed by diplopia. Muscle weakness is typically in the distribution of a single nerve, and pupillary light reflexes are usually spared. Complete spontaneous recovery usually occurs within 3 months.
