A chalazion develops when a meibomian gland, responsible for producing oils that lubricate the eye, becomes blocked and inflamed. This blockage leads to the formation of a painless lump under the eyelid, which can grow in size and cause redness, warmth, and tenderness.
In some cases, especially if the chalazion persists or grows larger, surgical removal may be necessary to alleviate symptoms and prevent complications. However, initial management typically involves applying warm compresses to the affected eyelid to help soften and release the blockage, promoting natural drainage and resolution of the chalazion over time.
