Stye

A stye, medically known as a hordeolum, is an inflammation of the oil glands of the eyelid that leads to a red, painful lump resembling a pimple. It is typically caused by a bacterial infection, most commonly Staphylococcus aureus. Styes can be external or internal, depending on the affected gland's location. External styes involve the eyelid margin, often affecting the hair follicles of the eyelashes, while internal styes occur within the meibomian glands located on the inner surface of the eyelid.

Symptoms of a stye include localized swelling, tenderness, pain, redness of the eyelid, and sometimes, the presence of pus. A stye may also result in the sensation of a foreign body in the eye, tearing, and sensitivity to light. Most styes resolve on their own without medical intervention within a week or two, aided by warm compresses, which help the stye drain and heal more quickly. However, persistent or recurrent styes might require medical treatment, such as antibiotics or, in some cases, surgical drainage. It's important for individuals with styes to maintain eyelid hygiene and avoid squeezing or puncturing the stye to prevent the spread of infection.
