What Are Styes and Chalazia?
A stye (also called a hordeolum) is a small, red, painful lump that grows from the base of your eyelash or under the eyelid. Most styes are caused by a bacterial infection.
There are two kinds of styes:
External hordeolum: A stye that begins at the base of your eyelash. Most are caused by an infection in the hair follicle. It might look like a pimple.
Internal hordeolum: A stye inside your eyelid. Most are caused by an infection in an oil-producing gland in your eyelid.
You can also get a stye if you have blepharitis. This is a condition that makes your eyelids at the base of the eyelashes red and swollen.
When you first get a stye, your eyelid is probably red and tender to the touch. Your eye may also feel sore and scratchy.
A chalazion is a swollen bump on the eyelid. It happens when the eyelid’s oil gland clogs up. It may start as an internal hordeolum (stye). At first, you might not know you have a chalazion as there is little or no pain. But as it grows, your eyelid may get red, swollen, and sometimes tender to touch. If the chalazion gets large, it can press on your eye and cause blurry vision. Rarely, the whole eyelid might swell.
What Is the Difference Between a Stye and a Chalazion?
Sometimes it can be difficult to tell the difference between a stye and a chalazion.
A stye is very painful. It often appears at the eyelid’s edge, usually caused by an infected eyelash root. It often swells, sometimes affecting the entire eyelid.
A chalazion is not usually painful. It is a bump that usually develops farther back on the eyelid than a stye. It is caused by a clogged oil gland. Rarely does it make the entire eyelid swell.
Stye and Chalazion Symptoms
Stye symptoms can include:
a very painful red bump along the edge of the eyelid at the base of the eyelashes. It may make the entire eyelid swell
usually a small pus spot at the center of the bump
having a scratchy feeling in the eye
being sensitive to light
tearing in that eye
A chalazion can develop and you might not see any symptoms. When there are symptoms, they can include:
a bump on the eyelid, sometimes becoming red and swollen. Occasionally it can be tender.
rarely, an entirely swollen eyelid
blurry vision, if the chalazion is large enough to press on the eyeball
Who Is At Risk for Styes and Chalazia?
Anyone can get a stye or chalazion. But you are even more likely to get one if you have:
Blepharitis, a problem that affects the edge of your eyelid
Had a stye or chalazion before
A skin condition, such as acne rosacea or seborrheic dermatitis
Diabetes or other medical problems
Stye and Chalazion Treatment
Here are ways to treat your stye or chalazion:
Warm compresses
Soak a clean washcloth in hot water and hold it to your eyelid for 10–15 minutes at a time, 3–5 times a day. Keep the cloth warm by soaking it in hot water often. For a chalazion, this warm compress helps the clogged oil gland to open and drain. You can help the gland clear itself by gently massaging around the area with your clean finger.
Antibiotics
Your ophthalmologist may prescribe an antibiotic for an infected stye.
Steroid shots
If your chalazion is very swollen, your ophthalmologist may give you a steroid shot (cortisone) to reduce the swelling.
Surgery to drain the area
If your stye or chalazion affects vision or does not go away, you may need to have it drained. This surgery is usually done in the doctor’s office using local anesthesia.
If a stye or chalazion keeps coming back time after time, your ophthalmologist may biopsy it. This is where a tiny piece of tissue is removed and studied. This helps your ophthalmologist check to see if there is a more serious eye problem.
Do not squeeze or try to pop a stye or chalazion
Doing so could spread the infection into your eyelid. Do not wear eye makeup or contact lenses while you have a stye or chalazion.
