Chalazion Meibomian gland lipogranuloma

A chalazion is a small bump in the eyelid caused by a blockage of a tiny oil gland.

A chalazion develops in the glands that produce the fluid that lubricates the eye. These are called Meibomian glands. The eyelid has approximately 100 of these glands, which are located near the eyelashes.

A chalazion is caused by a blockage of the duct that drains one of these glands

• Eyelid tenderness
• Increased tearing
• Painful swelling on the eyelid
• Sensitivity to light
  
  Chalazions are non-infections inflammations of the meibomian glands. This is different from a stye, which is an infection of a sweat-gland or hair follicle, similar to a pimple.

  A chalazion will often disappear without treatment in a month or so.

  The primary treatment is to apply warm compresses for 10-15 minutes at least four times a day. This may soften the hardened oils blocking the duct, and promote drainage and healing.

  If the chalazion continues to get bigger, it may need to be removed with surgery. This is usually done from underneath the eyelid to avoid a scar on the skin.

  Antibiotic eye drops are usually used several days before and after the cyst is removed. However, they are not much use otherwise in treating a chalazion.

  Steroid injection is another treatment option.

  

  
  
  Chalazia usually heal on their own. The outcome with treatment is usually excellent.
  A large chalazion can cause astigmatism due to pressure on the cornea. This will get better when the chalazion is treated.
