STY,also called Hordeolum, in medicine,is an infection of an eyelid gland. Two types are distinguished, the external and the internal sty.
The external sty is an infection, usually with staphylococcus organisms, of a sebaceous gland in the margin of the eyelid.
An internal sty is a staphylococcic infection of a meibomian gland, one of the modified sebaceous glands that lie close under the lining of the eyelids. These infections are more painful than is the external sty because they are pressed between the eyeball and the fibrous plate--called the tarsal plate--in the lid.
