Herpes zoster ophthalmicus may rarely be complicated with ocular motor nerve palsies. The exact mechanism of the palsies is unclear. The present report describes a case of herpes zoster ophthalmicus complicated with an oculomotor nerve palsy. A 85-year-old woman who had suffered from right herpes zoster ophthalmicus developed ipsilateral oculomotor nerve involvement 12 days later. The patient was treated with acyclovir and prednisolone. We report the case with a brief review of the ophthalmoplegia associated with herpes zoster ophthalmicus.
