How to treat a lash mite infestation? - in detail
Treating an eyelash‑mite infestation requires a systematic approach that eliminates the parasites, prevents reinfestation, and restores ocular health.
The first step is accurate identification. Microscopic examination of lashes reveals tiny, translucent mites attached to the hair shaft. Confirmation guides subsequent actions.
Topical acaricidal agents constitute the primary therapeutic class. Products containing tea‑tree oil (5 % concentration) or permethrin (1 %) are applied directly to the lash line using a sterile cotton swab. Application should be performed once daily for three consecutive days, then a single follow‑up dose after one week.
Adjunctive hygiene measures reduce the risk of recurrence. All makeup instruments, pillowcases, and towels must be washed in hot water (≥ 60 °C) and dried on high heat. Contact lenses and storage cases should be disinfected with a hydrogen‑peroxide solution.
Mechanical removal can complement chemical treatment. Fine‑toothed tweezers, under magnification, extract visible mites and debris. This procedure reduces parasite load and alleviates irritation.
Systemic therapy is rarely necessary but may be considered in severe cases. Oral ivermectin (200 µg/kg) administered as a single dose has demonstrated efficacy against related ectoparasites. Consultation with a specialist is required before prescribing.
Follow‑up evaluation occurs two weeks after the initial regimen. Re‑examination of lashes confirms eradication; absence of mites indicates successful treatment. Persistent symptoms warrant repeat microscopy and possible adjustment of the topical agent.
Preventive education reinforces long‑term control. Advising patients to avoid sharing eye cosmetics, to replace mascara every three months, and to maintain regular eyelid hygiene minimizes future infestations.
