Allergic Conjunctivitis (Eye Allergies) Treatment in the Capital Region

Allergic conjunctivitis occurs when the immune system reacts to allergens that come into contact with the eyes. In response, the body releases chemicals such as histamine, which cause inflammation and typical allergy symptoms in the eyes.

This immune reaction leads to redness, itching, swelling, and tearing of the eyes. Many individuals with allergic conjunctivitis also experience symptoms of allergic rhinitis, such as sneezing or a runny nose.

The conjunctiva normally helps keep the eyes moist and protected. When exposed to allergens, however, this protective tissue can become inflamed and irritated.

There are several types of allergic conjunctivitis, often categorized by the timing and severity of symptoms.

Acute Allergic Conjunctivitis

Acute allergic conjunctivitis may occur suddenly after exposure to an allergen such as animal dander, pollen, or certain chemicals.

Allergic conjunctivitis usually affects both eyes and may cause a variety of symptoms. 

Common symptoms include: 

• Itchy eyes 

• Red or bloodshot eyes 

• Watery eyes 

• Swollen eyelids 

• Burning or irritation of the eyes 

• Stringy or watery eye discharge  

Many patients also experience additional allergy symptoms such as: 

• Sneezing 

• Runny or itchy nose 

• Nasal congestion  

The hallmark symptom of allergic conjunctivitis is intense itching, which helps distinguish it from bacterial or viral conjunctivitis. 

Allergic conjunctivitis occurs when allergens come into contact with the eyes and trigger an immune response.

Common triggers include:

• Tree, grass, or weed pollen
• Dust mites
• Pet dander
• Mold spores
• Smoke or environmental irritants
• Certain chemicals or fragrances

Individuals with other allergic conditions—such as seasonal allergies, eczema, or asthma—are more likely to develop allergic conjunctivitis.

Symptoms often worsen when pollen counts are high or when exposure to indoor allergens increases.

Diagnosis usually begins with a review of symptoms and a physical examination of the eyes.

Your allergist may look for:

• Redness of the conjunctiva
• Swelling of the eyelids
• Small bumps inside the eyelids
• Excess tearing
• If allergy triggers are suspected, additional testing may be recommended to identify the underlying allergens.

These tests may include:

• Allergy skin testing
• Laboratory allergy testing ordered through the patient’s preferred laboratory

Identifying the specific allergens responsible for symptoms helps guide treatment and prevention strategies.

Treatment focuses on reducing exposure to allergens and relieving eye inflammation.

Medications

Depending on symptom severity, treatment may include:

• Antihistamine eye drops
• Mast cell stabilizer eye drops
• Oral antihistamines
• Short courses of corticosteroid eye drops for severe inflammation

For individuals with persistent allergy symptoms, allergy immunotherapy (allergy shots or allergy drops) may help reduce sensitivity to allergens over time.
