Understanding Styes and Chalazia

Styes develop when bacteria get into the oil glands or hair follicles around your eyelashes. The most common bacteria that causes styes is Staphylococcus aureus, which normally lives on your skin. When this bacteria gets into small cuts or blocked pores around your eyelids, it can cause an infection that forms a stye.

Chalazia form when oil glands in your eyelid become blocked but not infected. These glands normally make oils that keep your tears from drying up too quickly. When a gland gets blocked, the oil builds up inside and creates inflammation that forms a firm bump under the skin.

Certain medical conditions make you more likely to develop styes or chalazia. People with these conditions often have changes in their oil glands or immune system that increase their risk:

• Diabetes or other conditions that affect healing
• Blepharitis or chronic dry eyes
• Skin conditions like rosacea or seborrheic dermatitis
• Previous history of styes or chalazia
• Hormonal changes that affect oil production

Your daily habits and environment can increase your risk of developing these eyelid bumps. Poor hygiene around your eyes is one of the biggest risk factors, along with contaminated makeup or contact lenses.

• Poor eyelid hygiene or touching your eyes with dirty hands
• Using old or contaminated eye makeup
• Not removing makeup before bed
• Sharing towels or makeup with others
• Wearing contact lenses with poor hygiene
• Dusty or dirty work environments

Staphylococcus bacteria and tiny mites called Demodex can contribute to eyelid inflammation and recurrent blockages. These organisms live naturally on your skin but can cause problems when they overgrow or get into the wrong places around your eyelids, especially in people with chronic or recurring eyelid problems.

Styes themselves are not contagious, but the bacteria that cause them can spread from person to person. Avoid sharing towels, pillowcases, or makeup with others while you have a stye. Wash your hands frequently and don't touch the infected area to prevent spreading bacteria.

Most styes heal within 7 to 10 days with proper treatment and warm compresses. Chalazia may take several weeks to months to resolve completely, especially larger ones. Some chalazia need medical treatment to go away completely, while others may shrink on their own over time.

It's best to avoid eye makeup while you have a stye or chalazion because makeup can irritate the area and make the problem worse. Replace any makeup that may have been contaminated before the infection started. Wait until the bump is completely healed before using eye makeup again.

Small styes and chalazia usually don't affect your vision at all. However, large chalazia can press against your eye and cause temporary blurred vision or astigmatism. Contact our office right away if you notice any changes in your sight or have trouble seeing clearly.

Good eyelid hygiene is the key to prevention. Clean your eyelids daily with preservative-free cleansers, replace makeup regularly, and treat any underlying conditions like blepharitis. Our ophthalmologists can recommend specific prevention strategies based on your individual risk factors and medical history.

Contact our office if your stye or chalazion doesn't improve within a few days of home treatment, gets worse, or affects your vision. We also want to see you if you develop fever, severe pain, or redness that spreads beyond your eyelid to your face.

Antibiotics can help with bacterial infections in styes, but they often have limited impact on chalazia since chalazia are not active infections. Our eye doctors will determine if antibiotics are right for your specific situation. Some cases need steroid injections or minor surgery instead of or in addition to antibiotics.

The minor surgery we perform for persistent styes and chalazia is done with local numbing medicine, so you won't feel pain during the procedure. We make the incision on the inner side of your eyelid to avoid any visible scars. Some swelling and mild discomfort may persist for a few days after the procedure.

Most chalazia are completely benign and not cancer. However, if you have chalazia that keep coming back in the same spot or look unusual, our ophthalmologists may recommend removing tissue to check under a microscope. This is especially important for older adults or if the bump doesn't look like a typical chalazion.

Warm compresses help by melting the thick oils that are stuck in your eyelid glands. The heat makes the oil flow more easily, which helps drain blocked glands and reduces inflammation. Consistency with warm compresses is more important than the exact temperature or timing.

Yes, children can develop both styes and chalazia, and they often respond well to gentle warm compresses and good hygiene. If your child has persistent or recurring eyelid bumps, or if the bumps affect their vision, our ophthalmologists can provide specialized pediatric eye care to help them heal safely.

Recurrent styes and chalazia often indicate an underlying problem like blepharitis, seborrheic dermatitis, or poor eyelid hygiene. Our doctors can evaluate your eyelids and recommend treatments to address the root cause. This might include prescription medications, specialized cleaning routines, or treatments for skin conditions.

While stress doesn't directly cause styes and chalazia, it can weaken your immune system and make you more likely to get infections. Stress may also lead to poor hygiene habits or touching your face more often. Managing stress through good sleep, exercise, and relaxation can support your overall eye health.

Never squeeze or pop a stye, as this can spread the infection and make it worse. It can also push bacteria deeper into your eyelid or cause the infection to spread to surrounding areas. Let styes drain naturally or seek professional treatment if they don't improve with warm compresses.

Chalazia can form in different types of oil glands in your eyelid. Meibomian gland chalazia are the most common and form in the larger oil glands. Smaller chalazia can form in the glands of Zeis or Moll. The treatment approach is similar regardless of which type of gland is affected.
