Hordeolum, commonly known as a stye, is small lump in the eyelid caused by obstruction of an oil-producing gland. Hordeolum may occur in the upper or lower lids, causing redness, swelling and some soreness.

Most styes respond to a simple at-home treatment of warm compresses placed on the eye for 15-20 minutes followed by some light lid massage. However, if the hordeolum does not diminish or recurs, medical attention is advisable. The stye may require draining along with the use of antibiotics or anti-inflammatory medications.

If the obstruction persists, scar tissue and pus may accumulate within the eyelid. This is known as a chalazion. Although a small chalazion may respond to warm compresses, larger lesions require surgical removal or corticosteroid injections.
