Red, swollen bumps on the eyelids are usually wheals or chalazia: 1. Wheals are acute purulent infections of the eyelid glands, mostly caused by staphylococcal infections, with typical acute inflammatory manifestations such as redness, swelling, heat, and pain. In the early stages of the disease, local hot compresses and antibiotic drops should be applied to the eye, and in severe cases, oral antibiotics should be administered at the same time. 2. Chalazion, or chalazion cyst, is a sterile chronic granulomatous inflammation of the lid gland, probably due to blockage of the lid gland and chronic irritation of the surrounding tissues by glandular secretions trapped in the lid. It presents as a round subcutaneous mass on the eyelid and usually does not have the acute inflammatory manifestations of a mydriasis. It can be promoted by hot compresses or intracapsular glucocorticoid injections, and those who fail to absorb it for a long time should be surgically removed, with complete removal of the cyst to prevent recurrence. For recurrent or elderly chalazia, pathological examination of the excised material should be performed to exclude chalazion adenocarcinoma.
