Stye (hordeolum) : Symptoms and Causes
◉ What is a stye?
A stye is a common, mild infection that forms within a few days on the edge of the upper or lower eyelid centered on the root of an eyelash.
It usually forms when an eyelash sebaceous gland (secrets sebum) or a sweat gland (secrets sweat) becomes blocked and infected (usually with staphylococci).
A stye is similar to a red bump, a boil, an acne pimple or a small red pimple filled with pus. This abscess should not affect vision, but can cause several discomforts: pain, itching, foreign body sensation. etc
It usually lasts one to two weeks, even if no treatment is received.
Stye also called "Hordeolum"
◉ What causes styes ?
Usually it is a combination of a sebaceous gland (Zeiss gland appended to the eyelashes or Meibomian gland) or a sweat gland (Moll's glands) clogged and a certain type of bacteria.
The germs in question are typically from the staphylococcal family, 90% to 95% of cases of styes are due to Staphylococcus aureus, Staphylococcus epidermidis being the second most common cause.
◉ There are two types of styes :
1- External styes: the most common type, they form on the outer part of the upper or lower eyelid. It can be caused by an infection of:
- An eyelash follicle: these are small holes in your skin from which eyelashes grow.
- The Zeiss gland: is a unilobaric sebaceous gland located at the edge of the eyelid. This gland produces an oily substance called sebum, which keeps eyelashes soft.
- The Moll Gland: Is an apocrine sweat gland located next to the base of the eyelashes on the edge of the eyelid.
2- Internal styes: They form on one of your inner eyelids (facing your eyeball). An internal stye is usually caused by an infection of the meibomian gland which produces oils that help keep the eyelid moist.
