A 60-year-old woman presented with the complaint of left upper eyelid ptosis. Eight weeks earlier she was treated with antiviral agents for herpes zoster ophthalmicus. Neuro-ophthalmic examination revealed pitozis and miyozis in her left eye. Based on apraclonidine and hydroxyamphetamine test results the patient was diagnosed as postganglionic Horner's syndrome. The rarity of Horner's syndrome following herpes zoster ophthalmicus and the importance of topical agents in its diagnosis are emphasized.
