Internal Stye: Symptoms, Categories, Causes, Risk Factors, Treatment and Complications

It is an inflammation of the eyelid associated with a small collection of pus. In most cases, the infection is caused by Staph bacteria.

Although uncomfortable and incredibly common, styes are generally not a cause for concern.

Often the bump is red and painful and looks like a boil or pimple. Although most styles form on the outside of the eyelid, some develop on the inside.

In most cases, styes get better in 1 week without medical intervention. External styles, or those outside the eyelid, may turn yellow and release pus.

Internal styles that appear inside the eyelid tend to be more painful.

Gently applying a warm compress to the stye helps release pus more efficiently and resolve pain and swelling. Sometimes a stye can come back.

Styes can be external or internal. Home remedies for styes include a warm compress and over-the-counter pain relievers.


Symptoms of the internal stye

The patient will have a painful red swelling on the eyelid that can cause the eye to tear and turn red. Sometimes styles can look like pimples.

Styes rarely affects both eyes simultaneously. An individual will generally have a single style on one eye. However, it is possible to have more than one style in the same look or one in each eye.

Symptoms of a stye can include:

  • A lump on the eyelid.
  • Swelling of the eyelid
  • Pain.
  • Redness.
  • Sensitivity.
  • Scab on the margins of the eyelids.
  • Burning sensation.
  • Drooping of the eyelid.
  • Itching of the eye
  • Blurry vision.
  • Mucus discharge from the eye.
  • Sensitivity to light.
  • Tear
  • Discomfort when blinking.
  • The feeling that there is an object in the eye.

The individual should speak to a doctor if the stye persists for more than one week, vision problems arise, if the swelling becomes particularly painful, bleeds or spreads to other parts of the face, or if the eyelid or eyes become red.

Categories and general causes

External stye

External styles emerge along the outer edge of the eyelid. They may turn yellow, pus-filled, and painful to touch. An infection of the following can cause them:

Eyelash follicle: the small holes in the skin of the eyelashes grow.

A sebaceous gland (Zeis): This gland is attached to the eyelash follicle and produces sebum. The sebum helps lubricate the eyelashes and prevents them from drying out.

Apocrine Gland (Moll): This gland also helps prevent eyelashes drying out. It is a sweat gland that empties into the eyelash follicle.

Internal Orzuelo

The swelling develops inside the eyelid. In general, an internal stye is more painful than an external one. They are also known as internal stye and are usually due to an infection in the meibomian gland.

These glands are responsible for producing a discharge that is part of the film that covers the eye.

Patients may also experience a burning sensation in the eye, crusting on the eyelid margins, drooping of the eyelids, itchy eyeballs, sensitivity to light, tearing, a sense of something sticking to the eye, and discomfort when blinking.

Risk factors for internal stye

The following can increase your risk of developing a style:

  • Use cosmetics after their expiration dates.
  • She does not remove her eye makeup before going to bed.
  • Do not disinfect contact lenses before putting them on.
  • Change contact lenses without washing your hands thoroughly.
  • Teens tend to get styes more commonly, but people of any age can develop them.
  • Bad nutrition.
  • Sleep deprivation

If a family member has a style, the other residents should not share washcloths or face towels to minimize cross-infection.

Sometimes a stye occurs as a complication of blepharitis, an inflammation of the eyelids. Blepharitis is often caused by a bacterial infection but can sometimes be a complication of rosacea, an inflammatory skin condition that primarily affects the skin on the face.


A warm compress can be helpful in some cases of stye.

Most styes go away on their own without the need for any treatment. As soon as they break, the symptoms tend to improve quickly.

Don’t try to pop a stye yourself.

A warm compress held gently against the eye can help relieve symptoms. The water shouldn’t be too hot. Special care should be applied to another person, such as a child.

The compress should be held against the eye for 5 to 10 minutes, three or four times a day.

The compress not only relieves discomfort it can also encourage drainage of pus. Once the pus has been used up, symptoms usually improve quickly.

Pain relievers such as ibuprofen or acetaminophen may be helpful if the style is particularly sore.

When an external stye is extremely painful, the doctor can remove the closest eyelash and drain the pus away with a fine needle. This procedure should only be carried out by a professional. If things do not improve, the patient may be referred to a specialist, for example, an ophthalmologist.

If the stye persists, your doctor may prescribe a topical antibiotic cream or eye drops. If the infection extends beyond the eyelid, oral antibiotics may be prescribed.

It is best not to apply eye makeup, lotions, or wear contact lenses until the stye is wholly gone.

Complications of the internal stye

Complications, although extremely rare, can sometimes occur.

These may include:

Meibomian cyst: it is a cyst of the small glands located in the eyelid. The glands discharge a lubricant, called sebum, on the edge of the eyelid. A persistent style on the inside of the eyelid can eventually turn into a meibomian cyst or chalazion, especially if the gland is blocked.

This type of cyst is efficiently and effectively treatable.

Preeptal or periorbital cellulitis: This can develop if the infection spreads to the tissue around the eye. The layers of skin around the eye become inflamed and red, causing the eyelids to become red and swollen. This is treated with antibiotics.

Although complications can occur, as mentioned above, most stye cases will clear up with minimal intervention.
