What condition is caused by microscopic mites that burrow into the eyelash follicles?

Blepharitis is an inflammatory condition of the eyelids that is commonly associated with the presence of microscopic mites, specifically Demodex mites. These tiny organisms inhabit the eyelash follicles and can lead to the inflammation of the eyelids. Symptoms of blepharitis include redness, irritation, flaky skin around the eyelashes, and crusting of the eyelids upon waking due to oil and debris accumulation caused by the mites.

While the other options refer to different conditions, blepharitis is distinct in its direct association with these microscopic mites burrowing into the hair follicles of the eyelashes, leading to the characteristic symptoms of inflammation and discomfort. Understanding the relationship between Demodex mites and blepharitis can help in the diagnosis and effective treatment of this eyelid condition.
