C O M Ocular Allergy vs. Dry Eye Disease • One signature of ocular allergy vs. dry eye dis- ease is the mild time delay from interaction with allergen to symptoms, including puffy eyelids, red eyes and tearing. • Allergic issues are typically confined to the bul- bar and tarsal conjunctiva. • Allergies may have concomitant systemic mani- festations, including rhinitis, dermatitis and respi- ratory maladies.

Antihistamines can provide acute relief of redness and itching, while mast cell stabilizers can decrease or eliminate symptoms of an allergic attack when taken in advance (several weeks or more prior to allergy season). If the patient needs further improvement, I pre- scribe a topical steroid to be used two to four times daily. Antihistamines and mast cell stabilizers only address one aspect of the allergy cascade, but not the inflammatory cytokines, so steroids are sometimes needed. (See "Ocular Allergy Drugs," for a list of pharmacological options, p.17.) My last resort is to institute immunotherapy. Immunotherapy is treatment that uses your own body's defense system to help itself. Because I have identified, through allergy testing, what the patient is allergic to, I can prescribe the patient sublingual immunotherapy (SLIT) to be used at home daily to build up the patient's immune system. Basically, all things the patient is allergic to are reconstituted into drops that patients introduce into their bod- ies. rough the course of three to six months, the patient can administer drops under his or her tongue, which slowly through time, treats the underlying allergy and modifies the patient's im- PRIMARY EYE CARE PROVID- ERS ARE ON THE FOREFRONT OF TREATING ALLERGY.
