A Case of Ophthalmoplegia Caused by Herpes Zoster Ophthalmicus

Ophthalmoplegia may accompany herpes zoster ophthalmicus(HZO). A 60-year-old woman with rheumatoid arthritis suffered from HZO in the right side consecutively developed a mydriasis and abduction deficit in the right eye. CSF examination revealed pleocytosis and increased protein, while magnetic resonance imaging of the brain was normal. She was treated with intravenous acyclovir for 7 days. Ophthalmoplegia was completely resolved over the following 8 weeks, but mydriasis persisted.
