10 Causes of Chalazion
Cause #7: Untreated Styes
Chalazions and styes are often mistaken for each other. It is an easy mistake to make as, after all, they do look more or less identical. However, despite their similarities, the two are actually caused by different things. Whereas a chalazion is caused by a buildup of fluids due to a blocked gland, a stye is caused by a bacterial infection of the gland.
Styes are quite common and can suddenly appear. They will usually pass before long but they can sometimes linger. It is best to deal with them if they do linger and this might sometimes mean antibiotics. If it does go untreated, it may well end up forming a chalazion.
