Definition, causes, symptoms and treatment of A sty



A sty is a red, painful lump near the edge of your eyelid that may look like a boil or a pimple. Sties are often filled with pus. A sty usually forms on the outside of your eyelid. But sometimes it can form on the inner part of your eyelid.

In most cases, a sty will begin to disappear on its own in a couple days. In the meantime, you may be able to relieve the pain or discomfort of a sty by applying a warm washcloth to your eyelid.


Signs and symptoms of a sty include:

• A red lump on your eyelid that is similar to a boil or a pimple

• Eyelid pain

• Eyelid swelling

• Tearing

Another condition that causes inflammation of the eyelid is a Chalazion. A Chalazion occurs when there’s a blockage in one of the small oil glands at the margin of the eyelid, just behind the eyelashes. Unlike a sty, a Chalazion usually isn’t painful and tends to be most prominent on the inner side of the eyelid. Treatment for both conditions is similar.


A sty is caused by an infection of oil glands in the eyelid. The bacterium staphylococcus is responsible for most of these infections.


You are at increased risk of a sty if you:

• Touch your eyes with unwashed hands

• Insert your contact lenses without thoroughly disinfecting them or washing your hands first

• Leave on eye makeup overnight

• Use old or expired cosmetics

• Have Blepharitis, a chronic inflammation along the edge of the eyelid

• Have Rosacea, a skin condition characterized by facial redness


In most cases, a sty doesn’t require specific treatment. A sty typically goes away on its own. Recurrences are common.

For a sty that persists, your doctor may recommend treatments, such as:


Your doctor may prescribe antibiotic eyedrops or a topical antibiotic cream to apply to your eyelid. If your eyelid infection persists or spreads beyond your eyelid, your doctor may recommend antibiotics in tablet or pill form.

Surgery to relieve pressure.

 If your sty doesn’t clear up, your doctor may make a small cut in it to drain the pus. This helps speed healing and relieve the pain and swelling.


To prevent eye infections:

Wash your hands.

 Wash your hands with soap and warm water or use an alcohol-based hand sanitizer several times each day. Keep your hands away from your eyes.

Take care with cosmetics.

 Reduce your risk of recurrent eye infections by throwing away old cosmetics. Don’t share your cosmetics with others. Don’t wear eye makeup overnight.

Make sure your contact lenses are clean.

 If you wear contact lenses, wash your hands thoroughly before handling your contacts and follow your doctor’s advice on disinfecting them.

Apply warm compresses.

 If you’ve had a sty before, using a compress regularly may help prevent it from coming back.

Manage Blepharitis.

 If you have Blepharitis, follow your doctor’s instructions for caring for your eyes.
