What is Allergic Conjunctivitis?
Allergic conjunctivitis is inflammation of the conjunctiva caused by an allergic reaction. When allergens come into contact with the eyes, the immune system releases histamine and other inflammatory substances, leading to itching, redness, and watering. The condition commonly affects both eyes and may occur seasonally or throughout the year depending on the trigger.
The condition is especially common in people with allergies, asthma, eczema, or sensitivity to environmental irritants.
Allergic Conjunctivitis – Symptoms, Causes & Treatment at ASG Eye Hospital
Allergic conjunctivitis is a common eye allergy that occurs when the conjunctiva reacts to allergens such as dust, pollen, smoke, pet dander, pollution, or seasonal changes. The condition causes redness, itching, watering, swelling, and irritation in the eyes. Unlike viral or bacterial conjunctivitis, allergic conjunctivitis is not contagious, but it can significantly affect eye comfort and daily activities. At ASG Eye Hospital, experienced eye specialists provide advanced diagnosis and personalized treatment for allergic conjunctivitis to help patients achieve long-term relief and healthy vision.
Types of Allergic Conjunctivitis
Seasonal Allergic Conjunctivitis
This is the most common form and usually occurs during certain seasons due to pollen exposure from trees, grass, or plants. Symptoms may worsen during spring and summer.
Perennial Allergic Conjunctivitis
Perennial allergic conjunctivitis occurs throughout the year and is commonly triggered by indoor allergens such as dust mites, mold, pet hair, and smoke.
Giant Papillary Conjunctivitis
This form is often associated with long-term contact lens use or irritation caused by foreign materials in the eye. It may cause mucus discharge and discomfort while wearing lenses.
Vernal Keratoconjunctivitis
A more severe allergic eye condition commonly affecting children and young adults, especially in warm climates. It may require specialized treatment to prevent corneal complications.
