What condition is indicated by inflammation of the eyelid margins due to blockage of eyelash follicles?

• A. Blepharitis
• B. Chalazion
• C. Stye
• D. Conjunctivitis

Answer: (A)

Blepharitis is characterized by inflammation of the eyelid margins, typically caused by blockage of the eyelash follicles, often due to seborrheic dermatitis or bacterial infection. This condition leads to symptoms such as redness, swelling, and crusting at the base of the eyelashes, which can be both uncomfortable and cosmetically concerning for patients.

In contrast, a chalazion is a cyst in the eyelid that arises from a blocked meibomian gland and is not primarily related to the inflammation of the eyelash follicles. A stye (or hordeolum) results from an acute bacterial infection of the eyelash follicle or sebaceous gland, presenting as a painful lump on the eyelid but is not a chronic condition of the eyelid margin. Conjunctivitis, on the other hand, is inflammation of the conjunctiva, characterized by redness and discharge, and it does not involve the eyelid margins specifically. Therefore, blepharitis is the appropriate term for the inflammation of the eyelid margins related to the blockage of eyelash follicles.
