Eyes | Ophthalmology | Eye allergy (Disease)
Eye allergies, or allergic conjunctivitis, a condition that affects millions of people. It is a condition that can occur alone, but often accompanies nasal allergy symptoms, such as sneezing, sniffling and a stuffy nose. And, while most people treat nasal allergy symptoms, they often ignore their itchy, red, watery eyes.
People with SAC (seasonal allergic conjunctivitis) usually note the onset of symptoms during the spring and fall, and frequently note symptoms of allergic rhinitis. Symptoms include itchy eyes, burning of the eyes and eye watering. In some cases, people notice sensitivity to the light and blurred vision. The eyes are usually red, and the eyelids may become swollen. When the inside of the eyelid (the conjunctiva) is also swollen, the eyes may have a watery, gelatinous-like appearance - this finding is called chemosis.
Causes and Risk factors
Allergens that may be present indoors or outdoors can cause eye allergies. The most common outdoor airborne allergens are grass, tree and weed pollens. People who are sensitive to these allergens suffer from seasonal allergic conjunctivitis, the most common type of eye allergy.
Pet hair or dander, dust mites and molds are the most common indoor allergens. These indoor allergens can trigger symptoms for some people throughout the year, resulting in perennial allergic conjunctivitis.
Diagnosis and Treatment
If avoidance of allergic triggers fails to prevent symptoms of allergic conjunctivitis, some people notice mild benefit from cold compresses on the eyes, and eyewashes with tear substitutes. However, medications may be necessary to treat the symptoms. Medications for allergic conjunctivitis include oral anti-histamines and eye drops. ...
