Chalazion cyst nhsmail
A chalazion is a type of cyst that forms on the eyelid, typically on the upper eyelid. It is a benign (non-cancerous) lump that is caused by a blockage in the meibomian gland, which is a small gland located in the eyelid that produces oil to help lubricate the eye.
A chalazion is usually caused by a combination of factors, including:
- Blockage of the meibomian gland: This can occur due to a variety of reasons, such as a buildup of oil, bacteria, or other debris in the gland.
- Inflammation: The blockage can cause inflammation in the gland, leading to the formation of a cyst.
- Hormonal changes: Hormonal fluctuations during pregnancy, menstruation, or menopause can cause changes in the meibomian gland, leading to the formation of a chalazion.
- Poor eyelid hygiene: Failure to properly clean the eyelids can lead to a buildup of bacteria and other debris, which can cause a chalazion to form.
Symptoms of a chalazion may include:
- A small, painless lump on the eyelid
- Redness and swelling of the eyelid
- Discharge or pus from the cyst
- Eye irritation or discomfort
- Blurred vision
Treatment for a chalazion typically involves draining the cyst and removing any blockages in the meibomian gland. This can be done through a minor surgical procedure, such as:
- Incision and drainage: A small incision is made in the eyelid, and the cyst is drained. The blockage in the meibomian gland is then removed.
- Laser therapy: A laser is used to break up the blockage in the meibomian gland, allowing the oil to flow freely again.
- Warm compresses: Applying a warm compress to the eyelid can help to soften the blockage and encourage it to drain.
In some cases, a chalazion may resolve on its own without treatment. However, if the cyst becomes infected or causes significant discomfort, medical attention may be necessary.
It's worth noting that a chalazion is different from a stye, which is a small, painful bump on the eyelid caused by a bacterial infection. While both conditions can cause discomfort and eye irritation, a chalazion is typically a benign condition that can be treated with minor surgery or other non-invasive procedures.
