What is a stye?
A stye is a small, red, painful lump on the eyelid that may contain pus. It is usually caused by obstruction and inflammation of the Meibomian glands located within the eyelid, but can also be caused by an inflammation of the Zeiss glands (sebaceous glands of the palpebral edge). It can be found both on the inside and outside of the eyelid.
It should not be confused with a chalation, which is a cyst on the eyelid caused by an obstruction of the Meibomian gland. Unlike a stye, a chalation is not painful.
The symptoms produced by a stye are
- A red, painful lump on the eyelid that may contain a small spot of pus in the center.
- Sense of a foreign object in the eye
- Swollen and inflamed eyelids
- Sometimes, difficulty in the palpebral opening due to mechanical effect.
- Sensitivity to light
Sties are usually caused by an infection of the Meibomian glands or the sebaceous glands of the eyelid (Zeiss glands). There are predisposing factors, the main one being a history of blepharitis. Other factors that favor its appearance can be hormonal changes or stress, which can decompensate blepharitis. Local factors related to the hygiene of the periocular region can also contribute, such as touching the eyes with dirty hands, the use of expired cosmetics or not removing eye makeup properly before sleep.
Usually sties disappear on their own without the need for specific treatment, although reappearances are frequent. For the treatment, it is recommended to apply warm water compresses on the eyelid for 5-10 minutes, massaging to help drain the obstructed gland, about 3 or 4 times a day. It is very important not to exert excessive pressure or try to remove the pus from a stye, as this could favour the extension of the infection in the eyelid. It is also recommended not to use contact lenses or makeup while having a stye.
Most sties are harmless, but if they don’t get better after 48 hours or the redness and swelling worsen, it is recommended to consult an ophthalmologist, who can suggest specific treatments for each case.
