Brief Summary

This study employed an experimental, prospective, longitudinal, before-and-after design to evaluate the efficacy of topical chlorhexidine wipes in treating blepharitis. The investigation focused on assessing signs and symptoms associated with Demodex Folliculorum blepharitis, including telangiectasia, ocular irritation, collarettes, foreign body sensation, tearing, eyelid erythema, and dry eye. Each subject underwent an assessment of the Demodex Folliculorum infection index through the epilation of four eyelashes, followed by direct visualization using optical microscopy. Additionally, the number of eyelashes with collarettes was categorized and graded as follows: Grade 0: 0-2 eyelashes per eyelid with collarettes; Grade 1: 3-10 eyelashes per eyelid with collarettes; Grade 2: ≥10 to ≤1/3; Grade 3: ≥1/3 - ≤2/3; Grade 4: ≥2/3 of eyelashes per eyelid with collarettes. Participants applied topical chlorhexidine wipes twice daily, in the morning and evening, to cleanse the eyelash area of both eyelids over a period of four weeks. A follow-up assessment was conducted at four weeks, during which another Demodex test was performed to ascertain the presence of the microorganism. At week ten, the same signs and symptoms evaluated in the initial assessment were re-evaluated for follow-up.

Outcome Measures

Primary Outcomes (1)

  • Reduction in Demodex folliculorum count per eyelash

    Mean number of Demodex folliculorum mites per eyelash (mites/lash) assessed by epilation of 4 eyelashes from the upper eyelid and 4 eyelashes from the lower eyelid and examination under light microscopy at 40× magnification. The outcome will be reported as the change in mean mites/lash from baseline to 8 weeks after treatment with chlorhexidine eyelid wipes.

    Baseline and 8 weeks

Secondary Outcomes (2)

  • Change in eyelash collarette grade

    Baseline and 8 weeks

  • Proportion of participants by Ocular Surface Disease Index (OSDI) severity category

    Baseline and 8 weeks

Study Arms (1)

Treatment of Blepharitis by Demodex Folliculorum Group

EXPERIMENTAL

The investigation focused on assessing signs and symptoms associated with Demodex Folliculorum blepharitis, including telangiectasia, ocular irritation, collarettes, foreign body sensation, tearing, eyelid erythema, and dry eye.

Drug: Eyelid Cleansing with Wipes Containing Topical Chlorhexidine

Interventions

Participants applied topical chlorhexidine wipes twice daily, in the morning and evening, to cleanse the eyelash area of both eyelids over a period of four weeks. A follow-up assessment was conducted at four weeks, during which another Demodex test was performed to ascertain the presence of the microorganism. At week ten, the same signs and symptoms evaluated in the initial assessment were re-evaluated for follow-up.
