Chalazia / chalazion mostly occur on the upper eyelid but they are also sometimes seen to occur on the lower eyelid. They may manifest in the eyelid of one eye, but sometimes they are also seen to occur on the eyelids of both eyes simultaneously. Chalazion may either be soft or firmer. When it is soft, it is often filled up with fluid.

Causes and pathogenesis –
The term chalazion is derived from Greek word Khalazion, which means ‘small hailstone’.
As said, chalazion is caused when a block occurs in one of the meibomian glands of the eyelids. These glands are present in both upper and lower eyelids. They produce a kind of oil which, along with tears, lubricates and moistens the eyes and also protect them. If the oil becomes too thick, it can block the glands leading to causation of chalazion. The glands also may get blocked due to inflammation.

Usually the meibomian glands are involved. The gland of Zeis may also be involved in rare cases. Sometimes chalazion is caused due to infection but infection is a rare cause.
Frequent or past infections and viruses affecting these glands are the causes of chalazia. Chalazia are said to be related to common inflammatory conditions like acne, chronic blepharitis, seborrhea etc and are seen in those who suffer from these conditions. Infection of the eyes and eyelids and viral conjunctivitis also cause chalazia many times.

Chalazion in Ayurveda
Utsangini is one of the diseases explained in the netra vartma gata rogas (diseases afflicting the eyelids). This disease closely resembles chalazion. According to modern texts, chalazion may appear on the upper or lower lid as against Ayurvedic explanation of Utsangini wherein it is said to manifest only on the lower lid. But due to similarity, utsangini can be compared to chalazion.
