A chalazion, also known as an eyelid or meibomian cyst, is a red bump that develops on the eyelid. This condition occurs when a small oil gland located just behind the base of the eyelashes becomes blocked, leading to the gradual formation of chalazia. While these growths are typically not harmful, they can cause discomfort and disrupt daily activities. Fortunately, there are several straightforward methods to manage chalazia. In certain instances, seeking medical intervention may be required.
What Causes Chalazia?
Chalazia can occur when the meibomian glands become blocked, preventing the secretion of the oily substance that keeps the eyes moist. Several factors can lead to the formation of chalazia, including conditions like rosacea, tuberculosis, various forms of dermatitis, and viral infections.
Understanding the Difference between Stye and Chalazion
There is often confusion between styes and chalazia, as they share some similarities. However, it is important to note the distinctions between these two eye conditions. Styes are characterized by painful, red bumps that develop along the edge of the eyelid, usually as a result of an infection. These bumps often have small pus spots in the center and can cause swelling of the entire eyelid. On the other hand, chalazia do not typically cause eyelid swelling and are not usually accompanied by pain. They tend to be located further back in the eyelid compared to styes.
It is worth mentioning that while styes can contribute to the growth of chalazia, these two conditions are separate and should not be confused with one another.
