Understanding Styes: Causes, Symptoms, and Treatment Options

A stye is a common eyelid infection that appears as a red, painful bump on the upper or lower eyelid. Styes occur when bacteria that normally live on the surface of your eyelid block an oil duct or when germs and dead skin cells get trapped on the edge of your eyelid. Most styes start as a pimple next to an eyelash and can last several days before bursting and healing.

Types of Styes

There are two main types of styes:

• External styes: These are usually visible on the surface of your eyelid and are easy to see. They form a red, painful bump that often develops a whitehead.

• Internal styes: These form deep inside your eyelid, on the underside. While they also cause a red, painful bump, their location prevents a whitehead from appearing on the surface of the eyelid.

Causes of Styes

Styes are typically caused by a combination of a clogged oil gland and a specific type of bacteria. Your body is covered with billions of friendly bacteria that normally coexist without causing problems. However, when conditions are right, the bacteria can overproduce and create a pimple-like infection.

What Is a Chalazion?

If the clogged gland that produces the stye never improves, scar tissue can form around it. The pain subsides, but a bump remains. This condition is called a chronic chalazion. In some cases, a small fluid-filled cyst may develop, requiring a doctor to cut open and drain the cyst.

Are Styes Dangerous?

In most cases, styes and chalazia are harmless and rarely affect your eyeball or eyesight. However, in rare instances, they can lead to severe infections of the face called cellulitis. If you experience significant pain or drastic swelling and redness of the entire eyelid, it's essential to see your eye doctor for proper treatment.

Who Is at Risk for Developing Styes?

Styes can occur at any age and tend to recur, especially in people who have ongoing eyelid irritation (blepharitis) or a skin condition called rosacea. Maintaining good eyelid hygiene and managing underlying skin conditions can help reduce the risk of developing styes.

Treatment Options for Styes

Some styes are short-lived and heal on their own, while others may require medical attention. If you have a stye that persists or causes significant discomfort, consult your eye doctor for the appropriate treatment. They may recommend:

• Warm compresses to help soothe the area and promote drainage

• Antibiotics to clear the bacterial infection

• Surgical drainage of the stye or chalazion if it doesn't respond to other treatments

The Bottom Line

Most styes heal naturally with consistent warm compresses and good hygiene, but avoid the urge to pop them as this can worsen infection. See a healthcare provider if you develop vision changes, spreading redness, or recurrent styes that don't improve within two weeks.
