allergic conjunctivitisAllergic conjunctivitis is a type of eye condition that is brought on by allergies. In allergic conjunctivitis, allergens such as pollen or mold spores make the eyes red, watery, and itchy.

The inside of the eyelid and the covering of your eyeball have a membrane known as the conjunctiva, which is susceptible to irritants and allergens. The risk of allergic conjunctivitis is higher during the allergy season, and it is a common condition among those who suffer from allergies. Essentially, this is your body’s way of responding to allergens, just like having a runny nose and itchy ears.

Causes and complications of allergic conjunctivitis

There are two main types of allergic conjunctivitis: acute and chronic. Acute allergic conjunctivitis is a short-term condition that takes place mainly during allergy season. It is characterized by swollen and watery eyes, along with a runny nose.

Chronic allergic conjunctivitis is less common, but it essentially means a person experiences allergic reactions all year round. It can be triggered by food, dust, and animal dander. The symptoms usually come and go.

The main cause of allergic conjunctivitis is allergens, with common ones being dust, mold, pollen, animal dander, and chemical scents from detergents or perfume.

Complications rarely arise, as allergic conjunctivitis is more of an annoyance and frustration to live with. Allergic conjunctivitis can impede on daily activities and affect concentration as you are distracted by the irritating sensation in your eyes.

Complications that may arise – although rare – include:

Diagnosis of allergic conjunctivitis

Your doctor will examine your eyes and review your previous allergy tests. They may request a new allergy test, as allergies can change within a few years’ time. Especially, if you never experienced allergic conjunctivitis previously, it could be a sign that a new allergy has developed.

Either a skin allergy test or a blood test to look for proteins and antibodies can help your doctor determine what you are allergic to.

Once the doctor uncovers your allergens, they can then recommend a treatment plan for you.
