Meibomian Cysts Chalazion

This is the commonest eyelid lump in all ages. It is caused by blockage of the meibomian gland orifice such that the secretions accumulate. A granulomatous inflammation is set up, which results in a painless, round, firm, slowly growing lump in the tarsal plate (Figure 15.3). The cyst can become infected, when it becomes red hot and painful. Treatment is by incision and curettage.
