Symptoms of Allergic Conjunctivitis
Redness, itching, blurred vision and watering of the eye. In severe cases the white of the eye may swell dramatically and balloon out between the eyelids. There may be a clear, stringy discharge from the eyes, as well as excessive tears, and if the lower eyelid is turned down it appears to be covered with a large number of tiny red bumps. |
Tests for Allergic Conjunctivitis
Blood and skin tests can be undertaken to identify the responsible substance in some patients. |
Treatment for Allergic Conjunctivitis

Simple eye drops available over the counter from chemists and containing artery-constricting medications can be used in milder cases.
