Blepharitis is a term that describes inflammation of the oil glands in your eyelids. These oil glands produce an important component of the tear film that lubricates the surface of your eye keeping your vision clear and your eyes comfortable. In blepharitis, the oil glands become blocked by inflammatory material or become infected. The frequency of blepharitis increases with aging and is more common in patients with rosacea. Common symptoms include eyelid redness or soreness, dry eye, burning, a foreign body or “gritty” sensation, and discharge that causes the eyelids to stick together on waking in the morning. Occasionally, a blocked gland may swell in size resulting in a chalazion or become infected by bacteria resulting in a hordeolum or stye.
