Management of Allergic Conjunctivitis

First-Line Therapy

The American Academy of Ophthalmology recommends using dual-action topical agents (antihistamine + mast cell stabilizer) such as olopatadine, ketotifen, epinastine, or azelastine as the most effective first-line therapy, providing rapid onset and treating acute symptoms while preventing recurrent episodes 1, 2
The American College of Allergy, Asthma, and Immunology suggests using cold compresses to reduce inflammation and provide symptomatic relief 3, 1
The use of refrigerated artificial tears (preservative-free) four times a day to dilute allergens and inflammatory mediators on the ocular surface is recommended by the American Academy of Ophthalmology 3, 1, 2
Avoiding eye rubbing is crucial, as it can worsen symptoms and potentially lead to keratoconus, especially in atopic patients 1, 2
The American Academy of Ophthalmology recommends a strategy of allergen avoidance, including hypoallergenic bedding, eyelid cleaners, frequent washing of clothes, and showering before bed 3, 1

The American Academy of Allergy, Asthma, and Immunology suggests using mast cell stabilizers (cromolyn sodium, lodoxamide, nedocromil, or pemirolast) for long-term prophylaxis, as they have a slow onset of action (requiring several days to 6 weeks for optimal response) 5, 2
The use of topical NSAIDs, such as ketorolac, can help reduce prostaglandin production and provide temporary relief from ocular itching 5, 2

The American Academy of Ophthalmology recommends using topical corticosteroids with a low side-effect profile, such as loteprednol etabonate, only for short courses (1-2 weeks) if symptoms do not improve within 48 hours with dual-action agents 1, 2, 4
The American College of Allergy, Asthma, and Immunology suggests monitoring intraocular pressure (IOP) baseline and periodically, as well as dilating pupils to evaluate cataract formation 1, 2
Monitoring for glaucoma, especially with prolonged use, is recommended by the American Academy of Ophthalmology 1, 2

The American Academy of Allergy, Asthma, and Immunology recommends using topical immunomodulators, such as cyclosporine 0.05% or tacrolimus, for severe cases that do not respond to above therapies 1, 2
Cyclosporine 0.1% is FDA-approved for the treatment of vernal keratoconjunctivitis in children and adults 2

The American Academy of Ophthalmology advises against using punctal plugs, as they can prevent the flushing of allergens and inflammatory mediators from the ocular surface 2, 4
The American College of Allergy, Asthma, and Immunology recommends avoiding oral antihistamines as primary therapy, as they can worsen dry eye syndrome and disrupt the protective barrier of the tear film 3, 1, 2, 4
The use of chronic vasconstrictors (>10 days) can lead to rebound hyperemia (medicamentosa conjunctivitis) 5, 2, 4
The American Academy of Ophthalmology suggests avoiding unnecessary topical antibiotics, as they can cause toxicity and are not indicated for allergic conjunctivitis 2

The American Academy of Allergy, Asthma, and Immunology recommends using topical corticosteroids to control severe symptoms and signs 2
Cyclosporine topical 0.05% at least four times a day can help prevent seasonal recurrences 2

The American Academy of Ophthalmology suggests consulting an allergist or dermatologist for patients with inadequately controlled disease using topical medications and oral antihistamines 2
The American College of Allergy, Asthma, and Immunology recommends considering immunotherapy (subcutaneous or sublingual) for achieving desensitization, although its use may be limited by cost, patient commitment, and risk of anaphylaxis 2
Direct ophthalmologic evaluation is necessary if there is no improvement to rule out vernal or atopic keratoconjunctivitis 4

The frequency of follow-up visits depends on the severity of the disease, etiology, and treatment response 2
Reassessment within 48-72 hours is necessary to confirm symptom improvement 4
Monitoring for keratoconus in patients with allergic conjunctivitis and atopic disease is crucial, as adequate control of allergies and avoiding eye rubbing are important to reduce the progression of ectasia 2
