Blepharitis is inflammation of the eyelid margins causing them to become red and swollen.

It is a common condition which can develop at any age but is more common in young children and people over 40. Individuals can experience repeated episodes followed by periods with no symptoms.

Treatment

Blepharitis is usually a long-term (chronic) condition, which means once it develops it can cause repeated episodes. 

There is no cure for blepharitis, but establishing a daily eyelid-cleaning routine can help control the symptoms and any dryness can be treated with artificial tear drops. Lid cleaning often needs to be continued indefinitely to prevent recurrence.

More severe cases of blepharitis may require treatment with antibiotic ointment applied to the eyelids or, antibiotic drops for the eyes and, in a few cases, steroid eye drops.Some patients benefit from antibiotics by mouth, particularly when the blepharitis is associated with a skin condition such as rosacea, antibiotics are usually required for at least four to six weeks and may need to be continued for many months.
