The climatic characteristics of this time change from hot and humid to hot and dry and windy, which often makes some eye diseases more likely to occur. The main causes of “red eyes” and “itchy eyes” in autumn are allergies and “pinkeye”, which we should actively protect against. Allergic conjunctivitis is conjunctivitis caused by exposure to allergic medications or other antigenic substances. Patients often have a history of allergies and may have systemic allergic symptoms, such as sneezing – allergic rhinitis. Patients are self-conscious of itchy eyes, photophobia, tearing, foreign body sensation, and in severe cases, conjunctival edema and eyelid redness. For the treatment of allergic patients, the first step is to eliminate allergic factors, followed by local cold compresses to relieve symptoms, and in severe cases, topical application of anti-allergy eye drops and oral anti-allergy medication. ”Red eye, also known as acute cataract conjunctivitis, is an acute disease that occurs in the spring and fall, with rapid onset in both eyes at the same time or at intervals, with a sensation of foreign bodies, tearing, burning and swelling of the eyelids, conjunctival congestion and a large amount of discharge. Treatment of “pink eye” should be done with sensitive antimicrobial drops and saline rinses of the conjunctival sac, with attention to preventing cross-contamination. Although “red eyes” and “itchy eyes” are very common symptoms, the identification of these two diseases from other diseases also requires detailed examination by a specialist and the scientific use of drugs, especially hormones and antibiotics, under the guidance of a doctor. By using a combination of Chinese and Western medicine – external and internal treatment, the symptoms of allergic conjunctivitis and “pink eye” can be relieved and the course of the disease shortened, so that you can spend autumn comfortably and return a clear world to you.
