What condition is characterized by inflammation of the eyelids?

Blepharitis is characterized by inflammation of the eyelids, which can occur at the base of the eyelashes. This condition often manifests as red, flaky, and itchy eyelids, and can be associated with various factors such as seborrheic dermatitis, bacterial infections, or allergies. Patients may experience symptoms like crusting along the eyelid margins, irritation, and sometimes loss of eyelashes.

Chalazion and stye, while both related to eyelid issues, involve localized swelling or bumps due to blocked glands. A chalazion arises from a blockage of the meibomian gland, leading to a firm, painless lump, while a stye (or hordeolum) is an acute infection of the eyelid's oil glands, causing pain and redness. Conjunctivitis, commonly known as pink eye, affects the conjunctiva rather than the eyelids themselves, resulting in redness, discharge, and irritation of the eye surface.

Thus, bleeding in the context of inflammation of the eyelids specifically aligns with blepharitis, making it the correct answer.
