How to treat Demodex mite on eyelashes? - briefly
Effective management involves daily lid hygiene using a 0.25 % tea‑tree oil or diluted baby‑shampoo cleanser, supplemented by topical ivermectin or oral anti‑parasitic agents for advanced infestations. Consultation with an ophthalmologist is essential to confirm diagnosis and tailor treatment.
How to treat Demodex mite on eyelashes? - in detail
Effective management of Demodex infestation on the eyelash margin requires a combination of mechanical cleaning, topical pharmacotherapy, and, when necessary, systemic medication.
The first step is thorough lid hygiene. Warm compresses applied for 5–10 minutes soften the secretions, allowing gentle removal of debris. Follow the compress with a cotton swab soaked in a diluted solution of tea‑tree oil (0.5 %–1 %) or a commercial lid scrub containing hypochlorous acid. Perform this routine twice daily for at least four weeks, cleaning the base of each lash and the surrounding skin.
Topical agents directly target the mites. Options include:
- Tea‑tree oil: 0.5 %–1 % solution applied to the lash line once or twice daily.
- Ivermectin cream 1 %: thin layer applied nightly; reduces mite density within 2–3 weeks.
- Metronidazole gel 0.75 %: applied twice daily; useful for associated inflammation.
- Benzyl benzoate 25 %: single application under occlusion; effective but may cause irritation.
When topical treatment fails or the infestation is severe, oral ivermectin (200 µg/kg) administered as a single dose, repeated after one week, can be considered. Monitor for adverse effects and adjust dosage for patients with hepatic impairment.
Adjunctive measures support recovery:
- Avoid eye makeup and contact lenses during treatment.
- Replace pillowcases, towels, and facial cloths weekly to prevent reinfestation.
- Maintain a humid environment to reduce skin dryness, which can favor mite proliferation.
Regular follow‑up examinations, ideally every two weeks, allow assessment of mite count via microscopic eyelash sampling and adjustment of the therapeutic regimen. Successful eradication typically manifests as reduced erythema, disappearance of cylindrical dandruff, and alleviation of ocular irritation.
