Seasonal allergic conjunctivitis: overview and treatment update.
Seasonal allergic conjunctivitis is rarely associated with permanent vision impairment; however, it is a relatively common condition that may compromise the quality of life. It may, in extreme cases, impair daily activities, including work. Numerous treatment options have become available for the relief of acute symptoms. Avoidance should always be the first line in therapy but, in most cases, is not practical, especially with pollen allergies. The use of saline eyedrops is simple and nontoxic, and it is effective in up to 30% to 35% of cases. It can and should be added to all other remedies to reduce adverse effects and cost by decreasing the need for other therapeutic options. Antihistamines and decongestants are useful treatment choices for the majority of cases. Ketorolac tromethamine may be helpful in relieving pruritus, but it offers little advantage over topical antihistamines. Corticosteroids may be used for severe cases for a limited time. If topical corticosteroids are being considered, an ophthalmologist should be consulted. Cromolyn sodium and lodoxamide ophthalmic solution may be helpful in the prophylaxis of symptoms during the allergy season, but these agents require frequent dosing. Olopatadine hydrochloride is a mast cell stabilizer and antihistamine that can be dosed twice a day. Immunotherapy is effective and should be offered to those who are intolerant or have allergic conjunctivitis refractory to medications.
