Hordeolum Externum: Causes, Symptoms, and Treatment

Hordeolum externum, commonly known as a stye, is a red, painful bump that appears on the eyelid. It is caused by a bacterial infection, usually staphylococcus aureus, and can occur on either the upper or lower eyelid. In this article, we will discuss the causes, symptoms, and treatment options for hordeolum externum.


As mentioned above, hordeolum externum is caused by a bacterial infection. The bacteria enter the hair follicle or oil gland on the eyelid, causing an infection. Certain factors can increase the risk of developing a stye, such as:

  1. Poor hygiene
  2. Using old or expired makeup
  3. Not removing makeup before going to bed
  4. Sharing eye makeup with others
  5. Having blepharitis, which is an inflammation of the eyelid

The most common symptoms of hordeolum externum include:

  • A red, painful bump on the eyelid
  • Tenderness and swelling
  • Burning or itching sensation
  • Crusting of the eyelid
  • Watery eyes
  • Sensitivity to light

If you experience any of these symptoms, it is important to seek medical attention to prevent the infection from spreading to other parts of the eye.


The treatment options for hordeolum externum may vary depending on the severity of the infection. Mild cases can often be treated at home with warm compresses applied to the affected area for 10-15 minutes several times a day. This can help to reduce swelling and promote drainage of the infected area.

In more severe cases, your doctor may prescribe an antibiotic ointment or oral antibiotics to help clear the infection. It is important to follow your doctor's instructions for treatment and to avoid wearing contact lenses until the infection has cleared up.

In conclusion, hordeolum externum is a common bacterial infection that can be easily treated with proper hygiene and medical attention. If you experience any symptoms of a stye, be sure to seek medical attention to prevent the infection from spreading and causing further complications.
