What is a Chalazion?

Chalazion

 

Introduction

A chalazion is a small lump or swelling that results from blockage of the meibomian or oil glands that line the eyelid margin. They are usually painless. This nodule or bump may develop on the upper eyelid (more frequently) or lower eyelid (less frequently) and resolve spontaneously. Initially, a small, mild tender, and the swollen area is noticed but may become painless in a few days. It is often confused with a stye (hordeolum).

A stye is different from chalazion, as it happens due to bacterial infection of the meibomian glands while a chalazion results from blockage of the gland’s duct. An untreated stye can result in the formation of a chalazion. A stye is painful while chalazion is usually painless.

What Are The Causes And Risk Factors Of A Chalazion?

Meibomian glands are tiny structures present on the upper and lower eyelids which produce oil to keep the eyes moist/lubricated. Inflammation or viruses can affect the glands and may result in chalazia.
