About this study

After being informed about the study and potential risks, all patients giving written consent will have a complete ophthalmological examination to determine eligibilty for study entry. At week 0, patients who meet the eligibility requirements will be randomized in a double blind manner (participant and investigator) in a 1:1 ratio using block randomization to lid wipes containing tea tree oil (TTO) and chamomile oil or baby shampoo (twice daily).

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Diagnosis of seborrheic blepharitis

Exclusion criteria

  • Patients with ophthalmological pathologies that may affect the tear film functions including ocular rosacea, contact lens use, history of any ocular surgery, or patients with systemic pathologies or those using systemic medications that may affect the tear film functions
  • Patients younger than 18-year-old
  • Patients who used any treatment for blepharitis within the 6 months prior to the examination

Treatment and study plan

Swabs containing tea tree oil and chamomile oil

Drug

Swabs will be used in 26 patients for 8 weeks and will be discontinued in the following 4 weeks.

Baby shampoo

Drug

Baby shampoo will be used in 23 patients for 8 weeks and will be discontinued in the following 4 weeks.

Primary outcomes

  1. Efficacy of the treatment assessed by the change in Blepharitis Symptom measure (BLISS) score

    Time frame: Change from Baseline at 4 weeks

    BLISS score is calculated according to the answers given to the questionnaire. Higher BLISS scores is related to a worse outcome. (Range is between 0 and 39)

  2. Efficacy of the treatment assessed by the change in Blepharitis Symptom measure (BLISS) score

    Time frame: Change from Baseline at 8 weeks

    BLISS score is calculated according to the answers given to the questionnaire. Higher BLISS scores is related to a worse outcome. (Range is between 0 and 39)

  3. Efficacy of the treatment assessed by the change in Blepharitis Symptom measure (BLISS) score

    Time frame: Change from Baseline at 12 weeks

    BLISS score is calculated according to the answers given to the questionnaire. Higher BLISS scores is related to a worse outcome. (Range is between 0 and 39)

Secondary outcomes

  1. Efficacy of the treatment assessed by the change in Demodex mite count by light microscopy

    Time frame: 0-4-8-12 weeks

    The number of mites in the epilated 4 eyelashes will be counted under microscope.

  2. Efficacy of the treatment assessed by the change in the Schirmer's test results

    Time frame: 0-4-8-12 weeks

    Dry eye evaluation will be made with Schirmer's test.

  3. Efficacy of the treatment assessed by the change in the tear breakup time

    Time frame: 0-4-8-12 weeks

    Dry eye evaluation will be made with tear breakup time.

  4. Efficacy of the treatment assessed by the change in the ocular surface disease index score

    Time frame: 0-4-8-12 weeks

    OSDI scores are calculated according to the responses to the questionnaire. Higher values are related to a worse outcome (range is between 0-100).

  5. Efficacy of the treatment assessed by the change in the non-invasive tear breakup time

    Time frame: 0-4-8-12 weeks

    Dry eye evaluation will be made with non-invasive tear breakup time.

  6. Efficacy of the treatment assessed by the change in the meibomian gland loss

    Time frame: 0-4-8-12 weeks

    Meibomian gland loss will be evaluated using anterior segment analysis system.
