Styes & Chalazion

What is the difference between a Stye & Chalazion?

Sty

A sty, also called hordeolum, is a small abscess of the oil gland associated with an eyelash hair follicle. It typically contains Staphylococcus aureus bacteria, the cause of staph infections. When a sty develops, a small area of the upper or lower eyelid or the corner of the eye becomes red, tender and swollen.

Chalazion

A chalazion, like a sty, is a swelling within the eyelid caused by inflammation of an oil gland. A chalazion differs from a sty in that it does not contain an active bacterial infection. A chalazion is sometimes the aftereffect of a sty. It is less tender but lasts longer.

Both may last a few day or weeks. Their cause is usually a bacterial infection and can affect people of all ages. We will discuss treatment options with you at the time of your evaluation.
