What is the medical term for inflammation of the eyelids?

Blepharitis
Conjunctivitis
Hordeolum
Chalazion

The correct answer is: Blepharitis

The correct term for inflammation of the eyelids is blepharitis. This condition is characterized by redness, swelling, and irritation of the eyelid margins, often due to issues such as seborrheic dermatitis, bacterial infection, or clogged oil glands. Patients with blepharitis may experience symptoms like itching, crusted eyelids, and the sensation of having something in their eyes. Conjunctivitis refers to the inflammation of the conjunctiva, which is the thin membrane that lines the eyelids and covers the white part of the eyeball, often caused by infections or allergens. Hordeolum, commonly known as a stye, involves an infection causing a painful lump on the eyelid, while a chalazion is a blockage of an oil gland that can result in a painless lump but is not an inflammatory condition like blepharitis. Each of these terms refers to different conditions affecting the eyes, further reinforcing why blepharitis is the correct answer.
