Blepharitis is a chronic eyelid inflammatory condition which often affects middle-aged and older patients. The condition occurs in between 20 and 50% of all patients older than 60 years. The cause is poorly understood despite extensive research. We know that it develops due to a combination of inflammation and infection of the glands and eyelid lashes of your eyelids. It is often associated with wit dry eyes. Dry eyes aggravate the inflammation of the eyelids and the two often co-exists in a vicious cycle. Eyelid glands often become blocked because of the above factors leading to the redness of the eyelids.
Recent research has highlighted the importance of parasitic infection in the development of blepharitis. Certain parasites such as Demodex can reside in the eyelash roots and lead to eyelid inflammation. These organisms are highly resistant to conventional treatments.
