PURPOSE: The comparison of the efficacy of swabs containing tea tree oil and chamomile oil and baby shampoo (BS) in the treatment of seborrheic blepharitis was aimed.
METHODS: This randomized, double-blind, parallel-group, active control, multicenter clinical trial included patients with seborrheic blepharitis using block randomization (BS, n=23; swabs, n=26). Patients were treated with BS or swabs for 8 weeks followed by 4 weeks of treatment withdrawal. Change in Blepharitis Symptom measure (BLISS), Demodex count, Ocular Surface Disease Index (OSDI) score, Schirmer test, tear breakup time (TBUT), noninvasive TBUT (NI-TBUT), corneal staining, and meibography at different visits (baseline, fourth, , and 12th week) were the main outcome measures.
RESULTS: Patients in both groups showed similar baseline parameters (P>0.05). Patients using swabs showed significantly lower BLISS scores compared with patients using BS at the 4th, 8th, and 12th week visits (3.6±6.1 vs. 6.3±4.5 P=0.011; 1.1±2.8 vs. 6.6±6.7, P<0.001; 0.9±2.8 vs. 5.7±6.6, P=0.002, respectively). Patients using swabs showed improvement in OSDI scores after 8 weeks of treatment compared with the baseline visit (P<0.001). Despite a similar Demodex reduction effect in both treatment arms even after 4 weeks of treatment (P<0.001), both treatment modalities did not show any effect on the other parameters.
CONCLUSION: Although both swabs and BS showed efficacy for the treatment of seborrheic blepharitis in terms of the Demodex reduction and symptomatic improvement, swabs may provide better symptomatic improvement. Four weeks of treatment discontinuation may not cause any recurrence in the symptoms or Demodex infestation.
