An enlargement of a long, thin oil gland in the eyelid.
Initially a chalazion shares the appearance of a stye: swollen eyelid with pain and irritation. After a few days the symptoms disappear leaving a round, painless swelling in the eyelid that grows slowly for the first week. A red or grey area may develop underneath the eyelid.
Typically caused by an obstruction of the gland opening at the edge of the eyelid.
Most chalazions disappear without treatment after a few months but always be sure to have any growths examined by a professional.
