What is Allergic Conjunctivitis? Allergic conjunctivitis is eye inflammation caused by an allergic reaction. Conjunctiva, the tissue that lines the inside of the eyelid and outside of the eyeball, keeps your eyelid and eyeball wet. Eye allergies or allergic conjunctivitis occurs when this tissue becomes inflamed. There are two types: acute and chronic. Acute allergic conjunctivitis is a short term condition most common during allergy season while chronic allergic conjunctivitis occurs more frequently. These eye allergies are commonly triggered by pollen and pet dander, which is why springtime aggravates symptoms. Eye allergies are not contagious and should not be confused with pink eye, an infection of the outer membrane of the eyeball and the inner eyelid. Irritants like dirt and smoke can also irritate the eye. This reaction is not considered an allergic reaction. Your physician or one of our NYC Board Certified Allergists can determine if you have allergic conjunctivitis. Allergic Conjunctivitis Symptoms Symptoms of allergic conjunctivitis include: RednessItchinessWatery eyesBurningSwollen eyelidsA feeling of dirt in your eyes If you experience these symptoms, contact one of our allergists for a quick allergist test and treatment. Allergic Conjunctivitis Diagnosis If you experience the above symptoms, then you should contact one of our allergy specialists. An allergist can diagnose allergic conjunctivitis with a review of your symptoms and an allergy test. Allergy testing allows your allergist to determine the triggers of your eye allergies. Our skin prick tests detect multiple allergies in less than 20 minutes. We ask that you refrain from taking antihistamines for 48 hours prior to your allergy test. When the diagnosis is uncertain, a scraping of your conjunctival tissue may need to be taken to examine your white blood cells. The tissue sample is then stained for eosinophils, a class of white blood cells that are present in tissue affected by an allergic reaction. After the diagnosis, we offer personalized treatment plans to help you feel better fast. Treating Allergic Conjunctivitis Topical antihistamines are the most effective treatments available to treat eye allergies. Over-the-counter options for topical antihistamine eye drops include Zaditor (ketotifen), Naphazoline (Vasocon) and Patanol (olopatadine). These eye drops can provide faster and longer-lasting relief than oral antihistamines. You can also apply a cool compress to your eyes to soothe itching and burning. It’s always best to reduce exposure to allergens. If you suffer from chronic allergic conjunctivitis, we recommend beginning immunotherapy (allergy shots). Allergy shots are very effective in controlling your eye allergy symptoms. You will also experience less sneezing, coughing, and asthma symptoms as well as nasal congestion.
