A stye is a small bump or swelling close to the edge of your eyelid, along the lash line. An internal stye, or hordeolum, is a stye on the inside of your eyelid.
While an internal or inner stye is less common than an external stye, one that occurs on the outer rim of the eyelid, internal styes can sometimes be worse or cause complications because they’re closer to your eye. This common eye infection usually goes away by itself.
An internal stye can happen on your upper or lower eyelid. It usually happens on one eye at a time, but you get them on both eyes. Most internal styes last for 7 days or less.
Signs and symptoms of an internal stye may be slightly different from an external stye, and you may not be able to see the stye directly if it’s on the inner eyelid.
You may have one or more of the following symptoms:
symptoms of an internal stye
- red or white bump along the base of the eyelashes
- lump or swelling on the eyelid
- swelling of the entire eyelid
- crusting on the eyelashes, eye, or eyelid
- oozing or fluid
- pain or soreness
- tearing or watery eyes
- feeling like there is something in your eye
- blurred vision
You can get a stye from an infection. An internal or inner stye is usually caused by a bacterial infection in an oil gland in your eyelid. On the other hand, an external or outer stye is usually caused by an infection in a hair or eyelash follicle.
You can get an infection from normal bacteria on your skin or in your body. A bacterial infection in your nose or sinuses can also spread to your eye and cause an internal stye. Wearing contact lenses or false eyelashes or using makeup brushes can also spread bacteria to your eyelids and eyes.
Internal styes aren’t contagious. You can’t catch a stye from someone else. However, you can spread bacteria from an internal stye to your eye. This can happen if you rub, pop, or squeeze a stye.
Internal styes are usually more painful than external styes. They may also last longer. A serious internal stye can sometimes become chronic and return after it heals. It can also cause a hardened cyst, or chalazion, on the inside of your eyelid.
According to a medical
If you have an internal stye, you can see your optometrist or other healthcare provider. In more serious cases, you may be referred to an eye specialist known as an ophthalmologist.
Your doctor can examine your eye to see if you have an internal stye. You may need a swab test to find out if you have an infection. A swab test is painless and takes only a few seconds.
Your doctor will dab a cotton swab along your eyelid. The sample will be sent to a lab to find out what kind of infection may be causing the internal stye.
