A 62-year-old woman with a history of raising dogs presented with itching of her left eyelids for 2 weeks. Slitlamp examination revealed lice and translucent ovoid nits on the eyelashes (Figure, A). There was no infestation of hair in other body regions. Based on the examination findings (Figure, B), a diagnosis of unilateral phthiriasis palbebrarum was made. Mechanical removal of the lice was attempted but not successful so the affected eyelashes were removed. The eyelids were then treated with 1 yellow mercuric oxide ointment, %, twice per day for 2 weeks, with resolution of the infestation.
