Woman With Periorbital Rash

A 68-year-old woman presented to the emergency department with pain, redness, and swelling of the right periorbital region for 5 days (Figure 1). Visual acuity was 20/25 bilaterally, and she had no deficits or pain with extraocular movements and no uptake of fluorescein to the corneas. There was some eyelid sparing. On further discussion, the patient noted that before symptoms onset she was at an outdoor flea market and experienced a "twitching" sensation of her eye. On the advice of a vendor, she rubbed a plant he provided around her eye to alleviate the symptoms (Figure 2).
