Recently, Ms. Wang always felt her eyes and nose were itchy after going out, and a sneeze after a while made her eyes uncomfortable. She used eye drops that never got better, and her eyelids also became red and swollen. She was afraid that the red eye would be infectious to others, so she went to the hospital eye clinic and was diagnosed with allergic conjunctivitis. In recent years, the incidence of allergic conjunctivitis has further increased due to air pollution, eye cosmetic use and unscientific use of contact lenses. When itchy eyes and itchy nose sneezing occur, a visit to the ophthalmology department is warranted for early detection and symptomatic management of the problem. Clinically, itchy nose is associated with allergic conjunctivitis because the five senses are connected. Allergic conjunctivitis usually manifests as oddly itchy, unbearable eyes, and can also be accompanied by conjunctival congestion, tearing, burning sensation, and gummy discharge. The closer to the corner of the eye, the more severe the condition becomes, but patients usually do not have eye pain or significant visual impairment. In addition to itchy eyes, patients may also experience symptoms of allergic rhinitis such as runny nose, nasal congestion, nasal itching and sneezing.
