Currently, the first step in the treatment of allergic conjunctivitis is to identify the allergen and remove it immediately, which usually gives good results. For example, if you are allergic to pollen, go outdoors less during the pollen season, use goggles or high efficiency air filters, etc. However, most allergic conjunctivitis does not always have the exact allergen identified, or the allergen type is complex and not easy to identify, which is the root cause of recurrent allergic conjunctivitis and not easy to cure completely. If the allergen cannot be identified for a while, then, first of all, the living environment should be improved, especially the air quality or indoor temperature, so that the impact of the allergen is reduced. Secondly, pay attention to nutrition and exercise, regularity of life and rest, and strengthening physical fitness. Because the improvement of physical health can make the body’s potential to fight against allergy attacks increase, and reduce and slow down allergy attacks. Again, local cold compresses or ice packs can be applied to the eyes to reduce discomfort, artificial tears can be used to spot the eyes locally, and rinsing can also be used to significantly reduce the concentration of allergens and inflammation-causing factors and improve symptoms. Drug treatment mainly includes 1, eye antihistamines: commonly used emetine, emetine, etc. 2, ocular vasoconstrictors: commonly used compound Cai Miaolin (Nasuada), via Miaolin, etc. 3, mast cell stabilizers: commonly used Lodosamide (Alamax), sodium cromoglycate, Vishalostat (research Lixin), Nedolomil, etc. 4, ophthalmic dual-action drugs to stabilize mast cells and antihistamine: commonly used Olopatadine Patanlo, ketotifen, etc. 5, ocular non-pyloric anti-inflammatory drugs: commonly used ketorolac, diclofenac sodium, flupinophon, etc. 6, lubricants: a variety of artificial tears such as tear Ran, Beyran, etc. If the symptoms are not relieved by treatment, short-term drops of glucocorticoid eye drops (commonly used in clinical practice are imported drugs Flomax eye solution, Bactrim eye solution, domestic drugs 0.5% cortisone eye solution, etc.). In case of combined ocular bacterial infection, topical antibiotics can be used. If there is a rash, redness, swelling and oozing on the eyelids and surrounding skin, use 3% boric acid solution as a wet compress 2-3 times a day. It is important to note that anti-allergy treatment can only control the symptoms of allergy, but it is difficult to completely cure allergic conjunctivitis, which is one of the reasons why allergic conjunctivitis remains untreated. The good news is that allergic conjunctivitis is mostly self-limiting, and as the patient’s body adapts to the environment and strengthens its resistance, allergy symptoms are expected to decrease. Patients with particularly severe symptoms that do not heal after years of treatment may also consider relocation therapy, which means moving from the area where you live to another, more distant area to live and live, and may receive better results. This is due to moving to a different location, away from the allergens of the original place of residence. The effects of allergic conjunctivitis on vision are generally not serious, but symptoms such as oddly itchy eyes can cause considerable distress to the patient’s life, and therefore, need to be taken seriously. In terms of treatment, as long as the allergen is identified and removed in a timely manner, there is hope for a complete cure. If the allergen cannot be found for a while, the symptoms can be effectively controlled and reduced by improving the living environment, strengthening the body, and actively treating and preventing the disease with medication under the guidance of a doctor.
