Understanding Chalazion: Causes, Symptoms, and Treatment Options

Chalazion (plural: chalazia) is a type of inflamed swelling in the eyelid that can be caused by a blockage of the meibomian gland, which is responsible for producing oil to keep the eyelids moist. The blockage can lead to a buildup of bacteria and other debris, causing redness, swelling, and discomfort in the affected eye.

Chalazia are usually not serious and can be treated with warm compresses, antibiotic ointment, or surgical drainage if necessary. However, they can be persistent and may recur if the underlying cause is not addressed. In rare cases, chalazia can become abscessed and require more aggressive treatment.

It's important to note that chalazia are different from styes, which are infections of the eyelid margin that can be caused by bacteria or viruses. Styes typically appear as a red, painful bump on the eyelid, while chalazia are usually more diffuse and may not be as tender. If you suspect you have a chalazion or stye, it's important to see an eye doctor for proper diagnosis and treatment.
