Survey of Ophthalmology
|January 1, 1982
Summary
Phthiriasis palpebrarum, an uncommon cause of eye inflammation, requires careful examination for diagnosis. Treatment involves mechanical removal of lice and nits, with medicated ointments and hygiene measures for effective eradication.
Area of Science:
- Ophthalmology
- Parasitology
- Dermatology
Background:
- Phthiriasis palpebrarum is an infrequent cause of blepharitis and conjunctivitis.
- It is often overlooked due to its uncommon nature.
Observation:
- Diagnosis relies on a high index of suspicion and meticulous examination of lid margins and eyelashes.
- Visible signs include the presence of pubic lice (Phthirus pubis) and their eggs (nits).
Findings:
- Mechanical removal of lice and nits is the primary treatment.
- Topical pediculicides, such as 1% yellow mercuric oxide or 0.25% physostigmine ointment, are effective when mechanical removal is incomplete.
- Systemic treatment with gamma benzene hexachloride shampoo for body lice, with precautions for vulnerable populations, is recommended.
Implications:
- Comprehensive treatment includes examining and treating family members, sexual contacts, and close companions.
- Disinfection of personal items and linens with heat (50°C for 30 minutes) is crucial for preventing reinfestation.
- Prompt diagnosis and thorough treatment are essential to resolve ocular inflammation and prevent transmission.
