Do your eyes itch after you’ve been near a cat? Do they puff up or run with tears when pollen is in the air? Allergies of the eye affect about 20% of Americans each year, and are on the rise. The same inhaled airborne allergens — pollens, animal dander, dust mite feces, and mold — that trigger allergic rhinitis (the familiar sneezing, runny nose, and congestion) can lead to allergic conjunctivitis (inflammation of the conjunctiva, the lining of the eye). It’s not surprising that people with allergic rhinitis often suffer from allergic conjunctivitis as well.
About 50% of allergic conjunctivitis sufferers, who tend to be young adults, have other allergic diseases or a family history of allergies. About 80% of eye allergies are seasonal; the rest are perennial (year-round). The symptoms are itchy and red eyes, tearing, edema (swelling) of the conjunctiva or eyelid, and a mucous discharge. Although it can be uncomfortable, you can rest assured that it is not a threat to your vision.
Diagnosing allergic conjunctivitis
Allergic conjunctivitis usually can be confirmed by your doctor based on your symptoms. Testing is not usually needed to diagnose the condition, but skin testing (the same kind that’s done for other allergic reactions) may help identify the allergens causing your symptoms.
If your symptoms don’t quickly respond to treatment, see your doctor in case you have a different condition. Dry eye, in particular, can mimic the symptoms of allergic conjunctivitis.
