A red and swollen bulge in the eye bag is considered to be a chalazion, which can be treated with medication or surgery as prescribed by the doctor. Chalazion may be caused by chronic conjunctivitis, blepharitis and other diseases that lead to the blockage of the outlet of the lid glands, which leads to the retention of glandular secretions in the lid and chronic irritation of the surrounding tissues. If the chalazion is small and the patient is not experiencing discomfort, it usually does not require treatment, and in some cases, it may absorb on its own over time. If the size of the chalazion is large, the patient may want to promote its absorption by applying localized hot compresses, or cooperate with the doctor to inject glucocorticoids into the cyst to promote chalazion absorption. If the chalazion fails to subside for a long time, the patient should seek medical treatment under local or general anesthesia for chalazionectomy. It is recommended that people with red and swollen bags under the eyes should consult a doctor for examination and treatment as prescribed by the doctor after clarification of the disease. Daily attention to eye hygiene, develop good eye habits, habits of life.
