What is Blepharitis?
Blepharitis is a common condition where eyelids become irritated, red and swollen. Crusting and dandruff-like scales along the lash line and eyelid edge are also regular features.
Blepharitis results from a build-up of oil, particles and/or microbes at the base of the eyelashes. Why these factors trigger this distinctive condition is not well understood.
If you’re diagnosed with blepharitis, you will also learn that it can be caused by demodex mites. While they are transparent and only a fraction the width of a hair, it is still usually an unpleasant surprise to find out that these tiny animals live in your oil glands and eyelash follicles.
However, more or less everyone has a demodex population; they are only an issue among the few people who have an adverse reaction to their presence.
Whatever the cause, blepharitis is usually an ongoing condition. This means that while treatment is necessary and effective, a permanent cure is unlikely. Blepharitis is usually mild, but should not be ‘put up with’ as it is a precursor to more serious conditions.
