Combined treatment modality including topical 20% fluorescein dye in the management of phthiriasis palpebrarum - A case series.

Abstract

Purpose:To study the clinical presentations and outcomes of phthiriasis palpebrarum (PP) managed with combined treatment modality comprising of 20% fluorescein dye, mechanical removal of the ectoparasites, and topical application of antibiotic eye ointment with paraffin base.Methods:This is a prospective interventional noncomparative hospital-based series of 13 patients of PP. All the patients underwent local application of 20% fluorescein dye over the eyelashes and eyebrows of both the eyes followed by the mechanical removal of all the ectoparasites and trimming of the eyelashes from the base followed by application of ophthalmic ointment.Results:Mean age of the patients was 28 ± 22 years (range 3–60 Years). Out of the total of 13 patients, 11 patients (85%) were having bilateral involvement. The mean duration of symptoms in 11 patients (rest 2 were accidental findings) was 4 ± 3 weeks (range 1–10 weeks). Three patients (23%) had a history of sexual contact with possible parasite-infested partners. Four patients (31%) had additional parasites in the pubic area or torso. All the patients were completely parasite free at the end of 1 month. There was no infestation of the treating medical personnel from the patient. The average follow-up was 8 ± 5 months (range 3–21 months)Conclusion:Itching and irritation of the eyes were the most common presentations of PP. Combined treatment modality comprising of 20% fluorescein dye, mechanical removal of ectoparasites, and topical application of antibiotic eye ointment with paraffin base is effective in the management of PP.
