A. Allergic conjunctivitis: It is spring, children’s hospital ophthalmology clinic “red eye” patients are incessant, there are many patients before coming to the hospital had antibacterial drops, antiviral eye medication without significant effect. It turns out that this is not a bacterial, viral infection caused by red eye, but an allergic inflammation of the conjunctiva, mainly manifested as red eyes, itchy, severe photophobia, tearing, foreign body sensation in the eyes, some patients are accompanied by allergic rhinitis or asthma. Its cause is related to light, heat, dust, pollen, insect mites and other stimuli, so most of the onset in the spring and summer, and once the eye disease that there is the possibility of recurrent attacks, point anti-allergy eye medicine can relieve the symptoms, but can not be cured. Therefore, preventive measures are especially important: 1. Children with allergies should minimize their visits to the countryside and sunny and dusty public places in spring and summer, and it is best to wear tinted protective glasses to avoid the stimulation of bright light, pollen and dust. 2, such as eye redness, itching, photophobia and tearing, point antibacterial, antiviral eye drugs have no effect on the consideration of the disease, promptly go to the hospital to confirm the diagnosis, the choice of effective drugs. 3, the attack of this disease itchy eyes, patients rub their eyes with their hands, easy to combine bacterial infection, to the hospital to wash the eyes can effectively relieve the condition. Refractive error: Children’s refractive error (including myopia, hyperopia, astigmatism) must rely on wearing glasses to correct has been gradually recognized, but when to wear glasses, how to assist treatment is ignored by many parents. According to clinical observation, parents of children’s refractive error treatment often have the following misconceptions; 1, poor vision is myopia or pseudomyopia. In fact, children’s low vision is not always caused by myopia, farsightedness, astigmatism or other eye diseases are also manifested as low vision, and their treatment methods are completely different, so children with poor vision should first go to the regular hospital examination to determine the cause, the right treatment. 2, blindly listen to advertising and propaganda, for non-standard treatment. Some advertisements in the society are quite attractive, such as a certain therapy, a certain instrument can cure myopia, farsightedness, strabismus, etc. The reason why these false advertisements have a market is to cater to the psychology of some parents who are reluctant to give their children glasses. We would like to remind you that so far, there is no method that can replace glasses in treating refractive errors in children worldwide. The majority of farsightedness and amblyopia can be cured by early lens wear and amblyopia treatment, and glasses can be removed. However, there is no cure for adolescent myopia, and wearing glasses can improve visual acuity and slow down the development of myopia to a certain extent. 3, not regular review, timely replacement of lens prescription. Both myopia and farsightedness change with age. Generally speaking, the former gradually deepens, while the latter gradually reduces. Therefore, children with glasses should be re-examined every six months, according to the refractive error and changes in visual acuity and timely adjustment of lens prescription, otherwise, it will cause eye adjustment fatigue or adjustment paralysis. Congenital dacryocystitis: soon after birth, the child is often tearing in one or both eyes, and there is more secretions, but the eyes are not red, antibiotic eye medication is not effective. Some parents believe that this is “heat” caused by, do not need to treat. In fact, these phenomena are likely to be “congenital dacryocystitis or lacrimal duct obstruction” caused, should promptly go to the hospital to flush the tear duct, clear diagnosis.
