Chronic blepharitis secondary to Staphylococcus aureus infection is a very common ocular disorder. Part of the treatment for this condition is to have the patient cleanse the lid margin with a soap/detergent product on a Q-tip, gauze pad or cloth. The purpose of the cleansing is to mechanically remove bacteria along with toxic or irritating substances produced during the infection. The traditional lid cleansing product is baby shampoo. Recently new lid scrub products such as 1-Scrub, OcuSoft, and Medmoor Eyelid Cleanser have been introduced. Although most detergents are bactericidal, baby shampoo and these new cleansers have not been assessed for this property. Therefore, we determined the bactericidal action of these products by mixing samples of these cleansers with S. aureus and determined how many bacteria were killed. All the products showed bactericidal activity against S. aureus.
