Louse Infestation of the Eyelids

Louse Infestation of the Eyelids

This refers to infestation of the margin of the eyelid with crab lice as a result of poor hygienic conditions. The small oval nits frequently hang from the eye-lashes (Fig. 2.16), causing inflammation of the margin of the eyelid with severe itching. Mechanical removal with forceps is a time consuming but effec-tive treatment. Application of a 2% mercury precipitate ointment over an extended period of time is also effective.
