Pus in the corner of the eye may be caused by a bacterial infection, usually Staphylococcus aureus, which often causes inflammation of the lid gland, resulting in abscesses and pus at a later stage. Once there is a large amount of pus producing thinning of the skin, an incision and drainage can be considered, and the pus can be gently squeezed out with a cotton swab. If the abscess cavity is large, drainage strips need to be placed to promote the discharge of pus, so that the newly generated pus can be discharged along the drainage strips without having to squeeze the pus every day. However, the drainage strips need to be replaced every two days or so, and anti-inflammatory drops and eye ointment should be used during the process of pus drainage, and appropriate oral antibiotics, such as cephalosporin or amoxicillin, can be used if there are no allergies. Usually, after anti-inflammatory treatment, the inflammation will gradually subside, the pus will also gradually decrease, and the abscess will gradually subside.
