What Is Blepharitis?

Blepharitis is the persistent inflammation of the eyelids. The membrane covering the eyelid and eyeball (conjunctiva) can also become inflamed. Blepharitis is a common condition and often occurs in otherwise healthy people. The condition rarely threatens the eye itself or causes permanent loss of vision.

Cause of Blepharitis

The exact cause of blepharitis is not known. However, it appears to be caused by an abnormality in the oil producing glands on the eyelids. These oil-producing glands are known as meibomian glands - hence another name for this condition is meibomitis.

Abnormal bacteria in and around these glands may contribute to the condition.

Blepharitis seems to be more common in people who have oily skin, dandruff, and dry eyes and is extremely common in people with rosacea.
