A stye (also spelled sty) or hordeolum is an inflammation of the sebaceous glands at the base of the eyelashes. They are harmless but can be very painful. They are generally caused by a Staphylococcus bacteria infection. They are particularly common in infants.
The stye may form on either the inside or the outside of the eyelid.
- An external stye (external hordeolum) is a purulent inflammation of infected eyelash follicles and surrounding sebaceous (Zeis) and apocrine (Moll) glands of the lid margin.[1] It shows as a tender, red swelling on the edge of the eyelid and will tend to drain itself quickly.
- An internal stye (internal hordeolum) will also be tender and may show external red swelling. Internal styes often take longer to heal because the abscess cannot drain as easily. These types of styes can also cause blurred vision and irritation.
Since a stye is technically a pimple, it can be popped. However, doing so is not recommended without technical experience.
A stye can be secondary, caused by blepharitis. A blocked oil gland near the eye, a chalazion, is often mistaken for a stye.[1]

[edit] Treatment and management
Most styes will drain on their own though this may be accelerated with a hot or warm compress. Styes typically resolve within 1 week with treatment. [2]
Medical professionals will sometimes puncture a particularly persistent or irritating stye with a needle, to accelerate its draining. Their spread or expansion can also be fought with the use of antibiotic ointment akin to Neosporin (e.g. Erythromycin Ophthalmic Ointment), a special version being available for styes, which can be applied in a ribbon along the lid, on either inside or out.
Various folk remedies call for holding a metal or wooden spoon against the stye [3][4] or the rubbing of a gold ring on the stye[5].
