Horner's Syndrome Following Varicella Vaccination.

A 52-year-old female with no significant past medical history presented with disseminated herpes zoster as well as a Horner's syndrome and retinal haemorrhages 3 weeks after receiving the varicella vaccine. The patient began treatment with valacyclovir, 1g three times per day, and gabapentin, 300mg three times a day, for pain. Over the following month, the rash and the retinal haemorrhages resolved. The ptosis and anisocoria also resolved over the following two months.
