Patients with allergic conjunctivitis can use sodium cromoglycate ophthalmic solution, dexamethasone ophthalmic solution, tobramycin dexamethasone drops, emethystine ophthalmic solution, and olopatadine ophthalmic solution, etc. Eye ointment is also somewhat effective. Eye medications made of corticosteroids should not be applied for a long time. Long-term use may cause high intraocular pressure, so regular follow-ups should be conducted at the hospital. Patients should not use hormonal drugs indiscriminately and should also disengage and avoid contact with allergens. Patients with chronic conjunctivitis should identify and treat the cause of the disease.
