What is a chalazion?
A chalazion is a small bump that appears on the eyelid due to an obstruction of the sebaceous glands, known as the Meibomian glands. Unlike a stye, a chalazion is generally less painful and develops more slowly. It can affect the upper or lower eyelid and, in some cases, affect vision if it becomes large.
How does a chalazion develop?
Chalazion development begins when the opening of the Meibomius glands becomes blocked, preventing the secretion of the oil needed for the tear film that protects the eye. This obstruction may be the result of infection, inflammation or, sometimes, no apparent cause. People with a tendency towards seborrheic dermatitis or rosacea are more likely to develop chalazions.
What are the symptoms of a chalazion?
Symptoms of a chalazion include a lump on the eyelid, a sensation of a foreign body in the eye, increased sensitivity to light, and in some cases, a slight drop in vision. It's crucial to differentiate a chalazion from a stye, the latter being generally more painful and associated with infection.
How is a chalazion treated?
Treatment of a chalazion is primarily aimed at reducing inflammation and unblocking the Meibomius glands. Treatment methods include:
Can chalazions be prevented?
Chalazion prevention is based on rigorous eye hygiene, including regular cleaning of the eyelids with appropriate products. Avoiding make-up and contact lenses when a chalazion is present can also reduce the risk of complications.
What's the difference between a chalazion and a stye?
A chalazion and a stye are two types of lesion that can affect the eyelids, but they differ in cause and location. A stye is an acute, often painful infection of the glands at the base of the eyelashes, caused by bacteria, principally Staphylococcus aureus. In contrast, a chalazion results from an obstruction of the Meibomius glands, leading to chronic inflammation without primary infection. Styes tend to resolve more quickly, while chalazions may persist or recur.
Are chalazions contagious?
No, chalazions are not contagious. They are caused by an obstruction of the sebaceous glands of the eyelid, and not by a viral or bacterial infection that could be transmitted to other people. However, it is always advisable to maintain good hand and eye hygiene to prevent any complications.
Which specialist should be consulted for a chalazion?
It is advisable to consult an ophthalmologist or dermatologist for the treatment of a chalazion. These specialists can thoroughly assess the condition, suggest a suitable treatment, and perform surgery if necessary. They will also be able to determine whether the lesion is indeed a chalazion or another eye condition.
Can make-up cause chalazion?
The use of make-up, particularly if the products are old or poorly preserved, can contribute to the appearance of chalazions by obstructing the Meibomius glands. Regular cleaning of make-up applicators and replacement of out-of-date products is essential to minimize the risk of chalazion development and other eye infections.
How can you tell a chalazion from a simple eye irritation?
A chalazion manifests itself as a round, firm bump on the eyelid, whereas eye irritation can be caused by a variety of factors, such as allergens, foreign bodies or infections, and is often accompanied by redness, tearing or itching without the presence of a distinct bump. If a lump is visible and persists for several weeks, it is likely to be a chalazion. A medical consultation can help clarify the diagnosis and choose the appropriate treatment.
