The chalazion is a chronic inflammatory lesion caused by the stagnation of the sebaceous secretion produced by Meibonian glands or other sebaceous glands.
The chalazion is usually painless. Apart from aesthetics problems, the chalazia of the upper eyelids, when they become too large, can press on the cornea and become the cause of astigmatism.
Treatment
It is rare that the chalazion heals on its own, in most cases the only suitable treatment is the surgical excision.
