What is a Stye (Hordeolum) and Chalazion (Eyelid Cyst)?
Stye (Hordeolum)
A stye (Medical Name: Hordeolum) is a red, painful swelling that develops at the base of the eyelash or on the eyelid. It usually develops as a result of bacterial infection. It is more common in people with eyelid inflammation (blepharitis). There are two types.
-
Internal Stye:
It is rarer. It is inside the eyelid. And it usually occurs as a result of bacterial infection of the sebaceous glands.
-
External Stye:
This type is most common. It is a bacterial infection that occurs in the root of the hair. It looks like acne. There is pain, tenderness and swelling.
Chalazion(Eyelid Cyst)
Chalazions are small lumps that develop when the oil glands, known as meibomian glands, in the eyelid become blocked or inflamed.
These lumps typically contain trapped oil deposits, which are unable to drain properly due to blockages or inflammation, often triggered by infection.
Chalazion structures can form on the inner or outer side of the eyelid.
They can cause symptoms such as redness, swelling, and a stinging sensation.
Also,
Temporary astigmatism or blurred vision may occur as a result of pressure from the chalazion cyst.
Most chalazion cases do not last more than a few weeks.
They heal spontaneously without any treatment.
However, in cases that last longer than a few weeks and do not heal spontaneously, surgical procedures may be necessary to relieve the blockage in the eyelid glands.
What is the Cause of Stye (Hordeolum) and Chalazion (Eyelid Cyst)?
A sty develops as a result of a bacterial infection, often originating in the root of an eyelash (the follicle). Inflammation of the eyelid glands occurs when the small oil glands within the eyelid become infected.
Chalazion occurs when the summer glands in the eyelid become clogged. If the inflammation of the eyelid gland does not drain or heal, it can turn into a chalazion.
What is the Difference Between a Stye (Hordeolum) and Chalazion (Eyelid Cyst)?
It can sometimes be difficult to distinguish a Stye from a chalazion.
A stye:
Is very painful. It usually occurs at the edge of the eyelid and is caused by an inflamed eyelash root. It usually swells and sometimes affects the entire eyelid.
A chalazion:
Is not usually painful. It is a lump that develops behind the eyelid rather than a stye. It is caused by a clogged sebaceous gland. And it is rare for it to cause swelling of the entire eyelid.
What Are the Symptoms of Stye (Hordeolum) and Chalazion (Eyelid Cyst)?
A stye usually starts with a red bump on the eyelid that looks like a pimple.
- As the stye grows, the eyelid begins to swell and become painful, and there may be watering in the eye.
- Most Styes swell three days before they burst and flow.
- Styes usually heal within a week.
A chalazion occurs as a hard swelling or cyst under the skin of the eyelid.
- Chalazion grows slower than a stye. If it gets big enough, it can block the view.
- Inflammation and swelling may spread and cover the eye area.
- The chalazion usually goes away within a few weeks without treatment.
Whose Stye and Chalazion Are More Seen?
These diseases can happen to anyone.
But;
- Eyelid inflammation
- Skin diseases such as acne rosacea or seborrheic dermatitis
- Oily skin structure
- Previous sty and chalazion
more common in such cases. Apart from these, reasons such as rubbing the eyes too often, wearing and removing contact lenses without washing hands, and sleeping without removing eye make-up increase the risk of developing these diseases.
How Is a Stye (Hordeolum) and Chalazion (Eyelid Cyst) Diagnosed?
The doctor will diagnose a sty or chalazion by carefully examining the eyelid. It can be difficult to distinguish the difference between a sty and a chalazion. If there is a hard swelling inside the eyelid, the doctor will likely diagnose a chalazion.
How to Treat Stye and Chalazion?
Especially since the appearance of the stye resembles a pimple, it is sometimes tried to be popped by the patients. This should never be done, otherwise the infection may spread to the eyelid and cause more serious problems.
-
Stye:
-
Often No Treatment Required;
Because the tip of most styes will burst and discharge spontaneously within 3-4 days.
-
Warm Dressing;
It will reduce pain and help the inflammation collect at the tip of the stye and burst and flow out. Make-up and contact lenses are suspended.
-
Eyelash Epilation;
If the patient has an external sty, the affected eyelash is pulled. Thus, the focus of infection is eliminated and the inflammation is drained.
-
The Front Sight is Emptied;
This procedure must be carried out by an ophthalmologist. A minor incision is made along the edge of the eyelid, followed by gentle pressure to facilitate the drainage of pus. Attempting this on your own is highly discouraged, as it could lead to the infection spreading further within the eyelid.
-
Drops Containing Antibiotic and Cortisone;
They help control infection and reduce inflammation. It is used as recommended by your doctor.
-
Antibiotic Pill;
Most of the time it is not necessary. If the infection has spread to the skin, it may rarely be needed to control it.
-
Chalazion:
-
Often No Treatment Required;
It resolves spontaneously in half of the patients. This can take 2-6 months. If it does not cause any discomfort to the patient, it can be expected without treatment.
-
Warm Dressing;
It reduces complaints such as pain, redness, swelling. It makes the solidified fluid in the cyst fluid and may facilitate its evacuation.
-
Massage;
Massaging the cyst after the warm dressing facilitates the discharge of the cyst.
-
Antibiotic Drops;
Since there is no infection in chalazion, it does not need to be used.
-
Operation;
When a chalazion persists despite all treatments or causes pressure on the eye, leading to visual impairment, surgical removal may become necessary. A minor incision is made on the inner side of the eyelid to drain and clean the cyst.
Stye vs. Chalazion: Frequently Asked Questions
What is the difference between a stye and a chalazion?
While both appear as bumps on the eyelid, a stye (hordeolum) and a chalazion have different origins. A stye is typically an acute, painful bacterial infection of an oil gland or eyelash follicle. It often looks like a red, sore pimple near the edge of the eyelid and can cause the entire lid to swell.
In contrast, a chalazion is a chronic, usually painless bump caused by a blockage in one of the small Meibomian (oil) glands.
Unlike a stye, a chalazion tends to develop further back on the eyelid and grows more slowly. While a stye is an active infection, a chalazion is a localized inflammatory response to trapped oils. Understanding this distinction is crucial for selecting the correct treatment path.
Is it safe to pop or squeeze a stye or an eyelid cyst at home?
No, you should never attempt to pop, squeeze, or drain a stye or chalazion yourself. Attempting to “pop” an eyelid bump can force the infection deeper into the eyelid tissues or spread the bacteria to other parts of the eye.
In severe cases, this can lead to orbital cellulitis, a serious infection that requires emergency medical intervention and can threaten your vision.
The skin on the eyelid is extremely thin and sensitive. Squeezing a chalazion specifically is ineffective because the blockage is deep within the gland, not on the surface like a typical skin pimple.
The safest approach is to allow the bump to drain naturally through the use of consistent warm compresses, which help soften the trapped oils and encourage healing without the risk of scarring or secondary infection.
What are the most effective home remedies for treating a stye?
The primary and most effective home treatment for both styes and chalazia is the application of warm compresses. To do this correctly, soak a clean washcloth in warm (not scalding) water and place it over the affected eye for 10 to 15 minutes, three to five times a day. The heat helps to liquefy the hardened oils in a chalazion and draws the pus to the surface in a stye.
In addition to heat therapy, you should maintain strict eyelid hygiene. Use a mild, tear-free baby shampoo or a dedicated eyelid cleanser to gently wash the base of your eyelashes. Avoid wearing contact lenses or eye makeup until the area has completely healed, as these can harbor bacteria and prolong the recovery period. Most styes will begin to improve within a few days of consistent home care.
How long does it take for a chalazion to go away?
The recovery timeline for a chalazion is generally much longer than that of a stye. While a stye may resolve within 3 to 7 days, a chalazion can persist for several weeks or even months.
Because it is a blockage rather than a simple infection, the body takes more time to reabsorb the trapped glandular material.
If a chalazion does not show signs of improvement after two to four weeks of consistent warm compress treatment, it may be considered “persistent.”
At this stage, an optometrist or ophthalmologist may recommend clinical interventions such as a corticosteroid injection to reduce inflammation or a minor surgical procedure (incision and curettage) to drain the cyst. Early and frequent use of heat is the best way to speed up this process.
When should you see a doctor for a bump on your eyelid?
Most eyelid bumps are harmless and resolve with home care, but you should seek professional medical advice if you experience any of the following “red flag” symptoms:
- The bump interferes with your vision or causes blurred sight.
- The entire eyelid becomes very red, hot, and painful (signs of spreading infection).
- The bump bleeds, has an irregular shape, or causes eyelash loss (which could indicate a more serious condition).
- The stye or chalazion returns repeatedly in the same location.
- The pain is severe and does not respond to over-the-counter relief.
A doctor can prescribe antibiotic drops or ointments for infected styes or perform a sterile drainage procedure for large chalazia that are pressing against the eyeball and causing astigmatism or discomfort.
