Children’s chalazion with pus can be treated with general measures, medication and surgery. 1. General measures: for small chalazion without obvious symptoms, hot compresses can promote its self-rupture and absorption. Larger chalazion can also be relieved by hot compresses to speed up the recession of the disease. 2. Medication: Children with small chalazion can use topical Decleor ophthalmic ointment under doctor’s guidance. Children with large chalazion need to cooperate with the doctor in local injection of glucocorticosteroids such as Semisol and Prednisone. If secondary infection occurs, antibiotic ophthalmic ointment such as levofloxacin and erythromycin should be applied according to the doctor’s instruction. 3. Surgery: If a large abscess is formed, it is necessary to perform an abscessectomy. If the cyst is large and drug treatment is ineffective, cystectomy should be performed. When children are found to have chalazion, they need to go to the hospital in time and cooperate with the doctor for active treatment, so as not to delay the condition. At the same time, it is necessary to strengthen the daily life management, pay attention to the cleanliness and dryness of the eyes.
