Chalazion is a very common childhood eye disease that initially presents as a small swelling that can be seen on the eyelid and grows in size over time. There are two types of chalazia, one is the conjunctival surface type, which presents with a dark red conjunctival surface. The swelling does not progress toward the skin surface of the eyelid. This type of child can be operated on through the conjunctival surface of the eyelid, in which a small incision is made on the conjunctival surface and the necrotic degenerative tissue in the chalazion cavity is simply scraped out. No scarring is left on the eyelid after surgery. Another type of chalazion is the skin-faced type. In this child, the chalazion granuloma progresses to the skin surface of the eyelid and the swelling gradually increases in size. A large amount of hemorrhagic necrotic tissue can be present in the cystic cavity of the swelling. This type of chalazion is more complex and if not treated aggressively, the cyst eventually ruptures, leaving a large irregular scar tissue on the skin surface, and a severe defect in the skin surface of the eyelid can cause ectropion of the eyelid. Therefore, it is more important to treat the skin surface type of chalazion early, otherwise it will form a skin scar after breaking through the skin surface, which will affect the appearance.
