Other

Follicular conjunctivitis.

Treatment

  1. Mechanical removal of lice and eggs with jeweler’s forceps.
  2. Any bland ophthalmic ointment (e.g., erythromycin) to the eyelids t.i.d. for 10 days to smother the lice and nits.
  3. Anti-lice lotion and shampoo as directed to nonocular areas for patient and close contacts.
  4. Thoroughly wash and dry all clothes, towels, and linens.
NOTE:

In children, pediculosis is suspicious for possible sexual abuse, and the involvement of social services and/or child protection agencies is recommended.

For chlamydial, toxic, and molluscum contagiosum-related conjunctivitis, see 5.2, CHRONIC CONJUNCTIVITIS.
