A chalazion is a cyst in the eyelid that is caused by inflammation of the meibomian gland , usually on the upper eyelid. Chalazions differ from hordeolums in that they are usually painless apart from the tenderness caused when they swell up.

A chalazion may build up over many weeks and will eventually lead to it bursting. A chalazion may eventually disappear on its own after a few months, though more often than not, some treatment is necessary. In some cases chalazions repeatedly reappear, causing patients cosmetic disfigurement.

Alternative name

Meibomian gland lipogranuloma

Signs and symptoms

• Painful swelling on the eyelid
• Eyelid tenderness
• Sensitivity to light
• Increased tearing
• Red eye

Treatment

In treating chalazions, warm compresses with cloth soaked in clean, warm water may be useful. More sucessful forms of treatment include homeopathy and surgical removal. Antibiotic eyedrops or ointments may be prescribed if the inflammation is likely to be bacterial in origin or if the risk of secondary infection is thought to be significant.

Complications

A large chalazion can cause astigmatism due to pressure on the cornea. This will resolve with resolution of the chalazion.
