noun. a common condition that causes inflammation of the eyelids
Blepharitis is characterized by redness, swelling, styes, cysts, and flaky crusts at the eyelid margin and along the lash line. Symptoms also include scratchy, swollen, tender, and irritated eyes.
Various types of bacteria can cause blepharitis. It may be chronic or acute in presentation. People with skin conditions such as rosacea, acne, and eczema are more prone to have flare-ups. Poor facial hygiene can also be a contributing factor.
There are various types of this condition. Anterior blepharitis occurs on the outside of the eye. You may see redness, swelling, and possibly crust near the line of the eyelashes. Posterior blepharitis happens near the inside of the eyelid where it contacts the eye and can be due to problems with the lubricating meibomian glands inside the eyelids. Both forms of blepharitis require treatment to maintain appearance and eye comfort.
