If a blepharocyst is purulent or has a broken surface or is even painful, it is likely to be a secondary infection, with a secondary bacterial infection forming a mydriasis. These cases should be treated with anti-inflammatory treatment, such as topical levofloxacin or tobramycin drops for local anti-inflammation and tobramycin eye ointment or gatifloxacin eye ointment for nighttime antibiotic coverage, which can ensure round-the-clock antibiotic coverage. If the rupture is severe or the degree of suppuration is heavy, antibiotics such as cephalosporin or amoxicillin can also be taken, provided they are taken without allergy, to significantly shorten the duration of the wheals. After the granuloma has gradually subsided, hot compresses can be applied again to promote the absorption of the pus and the gradual improvement of the chalazion.
