Chalazion is a common eye disease that occurs in children and is usually caused by chronic granulomatous inflammation of the eyelid due to obstruction of the outlet of the lid gland, resulting in storage of glandular secretions and chronic irritation of the surrounding tissue. In the early stages of the disease, there are no painful nodules on the eyelids, no redness or swelling of the skin, and no impact on the child’s vision or life. Because of this, parents often ignore the disease and delay it. When the nodules break down to the skin surface, forming skin surface granules, some secondary infection, long time not absorbed, delayed, parents regret. In the early stages of conjunctival chalazion, the lesion does not affect the skin surface, which is the best time to treat the disease. The surgery is performed under local anesthesia, and a small incision is made in the conjunctival surface to scrape out the necrotic degenerative tissue from the chalazion cavity. There is no scarring of the eyelid after surgery. The procedure is simple and less painful, and the child usually returns to normal after 24 hours. Therefore, parents of children with chalazia should pay early attention to early detection and treatment, and not delay the opportunity for treatment. When the chalazion progresses to the skin surface and becomes a skin surface granuloma, destroying the local tissue and forming a scar, surgery on the skin surface is required and the preoperative examination is more complicated and the surgery is performed under general anesthesia.
