Chalazion / Chalazia Directory
A chalazion is a firm lump or cyst that grows under the skin of the upper or lower eyelid. Chalazia (plural) are usually painless and develop when an oil gland in the eyelid becomes blocked or infected. Chalazia will usually go away on their own after a few months without treatment.
