Study Summary

Previous studies have shown the clinical and antimicrobial efficacy of eyelid hygiene with tea tree oil (TTO) in resolving chronic blepharitis. Cliradex® is a novel over-the-counter eyelid wipe which contains the most active ingredient of TTO. The present study is a single-centre, randomized, trial comparing Cliradex® eyelid hygiene and I-Lid 'n Lash® Hygiene, another over-the-counter eyelid wipe, without any medicinal ingredients, in treating chronic blepharitis. The Primary Outcome Measure will be the difference in change in the number of CFU's after 2 weeks treatment, between the groups. The Secondary Outcome Measure will be the difference in change in objective clinical signs and symptoms by performing a vision check, a questionnaire, and visual grading, of each participants' blepharitis after 2 weeks treatment, between the groups. The Tertiary Outcome Measures will be the difference in change in microbial CFUs and clinical signs and symptoms between the groups at the 4 and 6 week point, (2 and 4 weeks after discontinuing treatment), to evaluate if the treatment will produce a lasting effect.

Participants will be randomized into one of the treatment arms. They will use the appropriate treatment for two weeks. They will then be re-assessed. They will discontinue treatment at this time, and four weeks later, will be assessed one last time, to see if the temporary treatment provides a lasting effect. A sub-group of ten patients per group will also be randomized to an extra visit. This group will be assessed after two weeks of having stopped the wipes. The same testing and procedures will be performed at this appointment.

Study Description

Previous studies have shown the clinical and antimicrobial efficacy of eyelid hygiene with tea tree oil (TTO) in resolving chronic blepharitis. This randomized, outcomes-assessor masked, clinical trial aims to determine the efficacy of Cliradex®, which contains the most active ingredient of (TTO), as compared with I-Lid 'n Lash® Hygiene, in treating chronic blepharitis

Blepharitis is a family of inflammatory disease processes of the eyelid. It can be divided anatomically into anterior and posterior blepharitis. Anterior blepharitis refers to inflammation mainly centered around the eyelashes and follicles, while the posterior variant involves the meibomian gland orifices. Anterior blepharitis usually is subdivided further into staphylococcal and seborrheic variants. Frequently, a considerable overlap exists in these processes in individual patients. Blepharitis often is associated with systemic diseases, such as rosacea and seborrheic dermatitis, as well as ocular diseases, such as dry eye syndromes, chalazion, trichiasis, conjunctivitis, and keratitis.1-3

The pathophysiology of blepharitis involves bacterial colonization of the eyelids. This results in direct microbial invasion of tissues, immune system-mediated damage, or damage caused by the production of bacterial toxins, waste products, and enzymes. Colonization of the lid margin is in-creased in the presence of seborrheic dermatitis or meibomian gland dysfunction.1-3

Blepharitis can be difficult to manage because it is often chronic or tends to recur. Despite the cause, eyelid hygiene is the cornerstone of treatment for most cases of blepharitis. This includes the use of commercially available over-the-counter lid cleansing wipes. Previous studies have shown the clinical and microbial efficacy of lid scrubs with tea tree oil (TTO) in resolving chronic blepharitis; however, lid scrubs based on TTO are not convenient for self-administration and cause irritation in some patients.4-11

Cliradex® (Bio-Tissue, Miami, FL) is a commercially available cosmetic pad containing the most active ingredient of TTO, which also exerts potent anti-microbial effects which may eliminate the need for systemic and/or topical antibiotic therapy for blepharitis.

In this trial, the investigators propose to conduct a randomized, outcomes assessor masked, clinical trial to determine the clinical and antimicrobial efficacy of Cliradex® and I-Lid 'n Lash® Hygiene, in improving the signs and symptoms of blepharitis, as well as decreasing the microbial flora in these patients.
