Chalazion

Important
It is feasible that the major title of the record Chalazion is not the name you got.
Chalazion is a round, gradually arising, local swelling, in the type of a cyst positioned on the reduced or top eyelid. If one or even more of the air ducts that drain these glandulars is obstructed, the sebum builds up under the skin to create a cyst.

In unusual situations, if the cyst is huge, obscured vision could result due to press on the cornea, the front, clear part of the eye with which light passes. People that incorporates persistent swelling of the eyelids (blepharitis) might be vulnerable to reoccurrences.
