Brief summary: Manuka honey eye drops are used for dry eyes and blepharitis. Manuka honey has been proven to be useful for eczema, atopic dermatitis, wound healing, anti-bacterial, anti-parasitic and anti-inflammatory actions.

Detailed description: Ocular allergy is a condition that can affect a patient's quality of life. Symptoms of ocular allergy include but are not limited to red, itchy, swollen, foreign body sensation, watery, puffy or blurry eyes. irritation, redness, burning, foreign body sensation, dryness, pain and blurry vision. In many cases, ocular allergic conjunctivitis are due to seasonal allergens like pollen, mold or indoor allergens such as pet dander or dust mites.

Ocular allergy can be treated by avoidance of known allergens, reduction of allergens by use of HEPA filters, cleaning linens, etc, topical decongestants, over the counter and prescription topical non-steroidals, topical or oral antihistamines, mast cell stabilizers or topical or oral steroids.

Manuka honey is produced by bees that are associated with the flowers of the Manuka plant (Leptospermum scoparium) that grows in New Zealand. Manuka honey is different from other honeys because it has been shown to the more potent due to its higher methylglyoxal concentration.

Manuka honey has been used for its anti-oxidant, anti-bacteral and anti-inflammatory properties. It has been shown to be useful in healing eczematous skin lesions. This study will attempt to demonstrate topical anti-allergy use for ocular allergy.
