Bilteral Phthiriasis Palpebrarum

Abstract

A 24-year-old Chinese woman presented with persistent itching of both eyelids that had commenced 4 weeks prior. She had no history of systemic and ocular disease. Slit-lamp examination revealed numerous lice and nits firmly attached to the base and shaft of the eyelashes (Fig. 1A). Light microscopy revealed the internal structure of the adult Phthirus pubis and nits (Fig. 1B). Eyebrows, axillae, scalp, and pubic hairs were unremarkable. A diagnosis of bilateral phthiriasis palpebrarum was made definitely. The patient was treated with eyelashes trimming, in addition to mechanical removal of the lice and nits. She had resolution of symptoms. No lice or nits were observed on the eyelashes during the 2-month follow-up period.P. pubis infestation is a highly infectious parasitic disease that spreads rapidly and has been reported to be closely related to sexually transmitted infections. 1 The globally prevalent disease is also an indicator of poor hygiene. 2 Phthiriasis palpebrarum may be easily misdiagnosed as conjunctivitis or blepharitis. 3 PHOTO SUBMISSION
