The aim of the study was to compare the efficacy of lid swabs containing tea tree oil (TTO) and chamomile oil and baby shampoo (BS) in the treatment of seborrheic blepharitis.
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).
