Itchy eyes caused by rhinitis are mostly allergic rhinitis causing allergic keratitis, and the treatment includes symptomatic supportive therapy as well as medication. Symptomatic supportive treatment includes cold compresses, use of artificial tears; medication includes the use of topical antihistamines such as olopatadine, emetine eye drops, or systemic use of antihistamines such as loratadine, cetirizine, etc., or the use of mast cell stabilizers such as sodium cromoglycate eye drops. Some patients with allergic rhinitis may have allergic conjunctivitis, which is an allergic reaction in the conjunctival area of the eye. Such patients may experience itchy eyes during allergic rhinitis attacks. Common allergens that cause allergic conjunctivitis are similar to rhinitis, such as dust, animal hair, pollen, etc., which may cause an allergic reaction in the conjunctiva, resulting in itchy eyes. Treatment is mainly symptomatic such as cold compresses, use of artificial tears, or medication such as antihistamines and mast cell stabilizers. Cold compresses and artificial tears can temporarily reduce the symptoms of allergic conjunctivitis; antihistamines include topical olopatadine eye drops, or systemic use, such as oral loratadine, cetirizine, etc.; you can also use topical mast cell stabilizers, such as sodium cromoglycate eye drops. Please follow your doctor’s instructions for specific medication regimens.
