What is the Difference Between Chalazion and Stye?

🆚 Go to Comparative Table 🆚

A chalazion and a stye are both infections of the edge of the eyelid, but they have some key differences:

  • Chalazion: A chalazion is a less painful, chronic infection that affects the Zeis or meibomian (oil-secreting) glands on the conjunctival side of the eyelid. It is caused by a clogged oil gland and is usually not painful. A chalazion can sometimes grow large enough to cause blurry vision if it presses on the eye. Risk factors for chalazia include acne rosacea, chronic inflammation of the eyelids, poor eyelid hygiene, and meibomian gland dysfunction.
  • Stye (Hordeolum): A stye is a painful infected lesion that appears on the edge of the eyelid (eyelash follicles) and comes on quickly. It is usually caused by an infected eyelash root and can result in swelling, pain, and tenderness of the eyelid. Styes are contagious and more tender to the touch than a chalazion. If a stye is present for several weeks, it may develop into a chalazion.

Treatment for both conditions may include warm compresses, antibiotics, corticosteroid injections, or incision and drainage procedures, depending on the size, location, and persistent nature of the infection. It is important not to attempt to remove a stye or chalazion yourself, as it could cause the infection to spread. If you suspect you have either a chalazion or a stye, it is recommended to consult with an eye care professional for proper diagnosis and treatment.

    • Comparative Table: Chalazion vs Stye

    Here is a table comparing the differences between a chalazion and a stye:

    Feature Chalazion Stye (Hordeolum)
    Definition A blocked oil gland on the inside of the eyelid, usually surfacing as a bump A small, pimple-like bump on the upper or lower eyelid, typically near the eyelash and on the outside of the eyelid
    Cause Caused by a clogged oil gland Caused by a bacterial infection, often Staphylococcal, affecting the eyelid glands
    Pain Not usually painful Painful, sometimes extremely so, and often tender to the touch
    Location Develops farther back on the eyelid Often appears at the eyelid's edge, usually caused by an infected eyelash root
    Swelling Rarely causes the entire eyelid to swell Often swells, sometimes affecting the entire eyelid
    Symptoms Mild irritation causing eyes to water, blurred vision Redness, tenderness, pain, red or gray area on the underside of the eyelid, eyelid swelling
    Treatment Warm compresses, antibiotics (if infected), corticosteroid injections, or surgical incision Warm compresses, antibiotics (if infected)

    It is important not to attempt to remove a stye or chalazion yourself, as it could cause the infection to spread. Instead, schedule an appointment with a healthcare professional to discuss the appropriate treatment options.
