Itchy eyes is one of the complaints of ophthalmology patients, for the judgment of itchy eyes, mainly to see whether there is no accompanying other symptoms, such as no accompanying symptoms (no secretion, no fear of light, no conjunctival irritation symptoms, etc.), just simple itch, and itchy seasonal is very obvious, but also accompanied by itchy nose, running nose, sneezing and other allergic symptoms of the nose, then it may be due to allergies. As allergic conjunctivitis patients will feel itchy and uncomfortable eyes, many patients buy their own eye drops to treat, which is very dangerous. Dr. Fei emphasized that there are many reasons for itchy eyes, and if you can't treat the symptoms, it will cause damage to your eyes. For chronic allergic conjunctivitis, hormonal eye drops and anti-allergy drugs can quickly relieve the symptoms of itchy eyes, but only short-term use. If you use hormonal eye drops for a long time, it is very easy to lead to the lowering of eye resistance, increase the chance of infection, and also cause irreversible damage such as increased intraocular pressure, hormonal glaucoma, hormonal cataracts, optic nerve atrophy, and so on. For acute allergic conjunctivitis, it is recommended to use some hormone eye drops plus anti-allergic drugs for a short period of time according to the doctor's instructions; for chronic allergic conjunctivitis, it is recommended to do conjunctival cell scraping to find out the allergens, and then desensitization treatment, which can really achieve the "root cause" of the purpose. Another disease that accompanies itchy eyes is dry eye disease. Dry eye is the most common and prominent type of ocular surface disease, but also a hot spot in ophthalmology research. In the past, it was often diagnosed as chronic conjunctivitis. Dry eye has uncomfortable symptoms such as itchy eyes, dry eyes, and foreign body sensation in the eyes, but the ocular surface is good. Dry eye disease has symptoms such as dry eyes and other complaints, and the tear film is not intact, tear secretion is reduced; while dry eye syndrome is a kind of connective tissue disease, is a systemic systemic disease in the eye performance, and dry eyes may be accompanied by dry mouth and other symptoms. With the popularity of computers and TVs, the number of patients with dry eye syndrome is gradually increasing, because normal people blink 20 times per minute on average, but when both eyes are staring at the computer screen, the number of blinks per minute may be reduced to 6-7 times, and the main role of blinking is to moisturize the eyeballs, blinking times are reduced, and the degree of eyeballs moisturized is of course also reduced. For dry eye, it is recommended that under the premise of exclusion of ocular surface and systemic diseases, symptomatic medication can be prescribed, and some artificial tears can be put into the eye, such as Tear Ran, BeiFuShu, Aili and other eye drops. For long-term use, it is recommended to use preservative-free artificial tears to moisturize the eyeballs, thus relieving the symptoms of dry eyes.
