Inside Chalazion
Chalazion Overview and Comparison with Stye
A chalazion is a small, usually painless, lump or swelling on the eyelid. It occurs when a meibomian gland, which is a tiny oil-producing gland in the eyelid, becomes clogged. In contrast to a stye, chalazions typically grow more slowly and initially may not cause discomfort.
There are several key differences between a chalazion and a stye:
-
Location and Pain: A stye generally forms at the base of an eyelash and is associated with pain. A chalazion, however, develops further up on the eyelid due to a blocked oil gland and usually does not cause pain.
-
Appearance Over Time: Styes often turn into yellowish spots that may burst, releasing pus, after several days. Chalazions, on the other hand, grow more slowly and remain solid, not discharging pus unless there is a secondary infection.
Both conditions typically show improvement over time. Warm compresses have been mentioned in relation to expediting the healing process.

Symptoms, Causes, and Risk Factors for Chalazion
A chalazion is a small lump on the eyelid caused by a blocked oil gland. It can develop on the upper or lower eyelid and is not contagious.
The most common symptom of a chalazion is a painless bump or lump on the eyelid. Initially, it might resemble a stye but typically without significant pain. Other symptoms include:
- Swelling of the eyelid
- Increased tear production
- Sensitivity to light
- Blurred vision if the chalazion is large enough to press against the eyeball
Chalazions occur when one of the Meibomian glands (oil glands) in the eyelids gets blocked due to thickened gland secretions or other blockages. This blockage prevents oil from reaching the eye's surface, leading to inflammation and lump formation.
Several factors increase the likelihood of developing a chalazion:
- Previous Chalazia: Individuals who have had a chalazion before are more likely to develop another.
- Blepharitis: Chronic inflammation along the edges of the eyelids can lead to blockages.
- Skin Conditions: Conditions like acne rosacea or seborrheic dermatitis increase susceptibility.
- Poor Eyelid Hygiene: Not removing eye makeup properly can contribute to blocked glands.
- Use of Contact Lenses: Improper handling and lack of cleanliness can pose risks.
This information contributes to a broader understanding of chalazions, facilitating early detection and awareness of the condition.
