Overview
A stye (hordeolum) is an inflamed, swollen growth of the eyelid. Styes can occur at the edge of the eyelid or farther up the lid on either the inner (tarsal side) or the outer (skin side) of the lid. A chalazion is the chronic form of a stye, and its cellular makeup is different than that of a stye.

Both the meibomian and sebaceous oil glands of the lid can be involved in this process, which begins with a blockage of the normal openings of these glands, leading to the swelling. Typically, there is bacterial contamination.
