Inflammation in the corner of the eye can be caused by many diseases. For example, a localized red, painful lump in the corner of the eye may be blepharitis, which needs to be treated with anti-inflammatory medications, commonly known as ofloxacin eye drops, erythromycin eye ointment, and oral cephalexin medications, etc. Once the lump is found to be soft and a yellowish-white pustule appears, it needs to be treated with a prompt pus release. If the abscess is at the base of the eyelashes, the incision should be parallel to the lid margin; if the abscess is on the inside of the eyelid, the incision should be perpendicular to the lid margin. Localized skin congestion and erosion at the corner of the eye may be blepharitis, which may be caused by Staphylococcus aureus infection, or Mo-Abis infection, etc. Therefore, local treatment with antibiotics plus hormonal eye ointment, such as tobramycin dexamethasone eye ointment, is recommended. In addition, attention should be paid to the cleanliness of the skin around the eye and avoid the use of cosmetics.
