Anterior blepharitis involves which part of the eyelid?

• A. Retina.
• B. Conjunctiva.
• C. Skin and base of the eyelashes.
• D. Meibomian glands.

Answer: (C)

Anterior blepharitis affects the front part of the eyelid margin—the skin and the base of the eyelashes. This region lies at the lash line and includes the lash follicles themselves, so inflammation here produces crusting, scale, and irritation along the lid margin. In contrast, the Meibomian glands lie behind this margin and are involved in posterior blepharitis when inflamed. Therefore, the skin and base of the eyelashes is the correct structure affected.
