What condition is characterized by inflammation of the eyelid's membrane?

The condition characterized by inflammation of the eyelid's membrane is commonly known as Pink Eye, or conjunctivitis. This inflammation can affect the conjunctiva, the thin, transparent tissue that lines the inner surface of the eyelids and covers the white part of the eyeball. Symptoms of conjunctivitis can include redness, irritation, discharge, and watering of the eyes, which can also impact the eyelids.

In contrast, hives are a skin reaction that presents as raised welts on the skin, typically causing itching, but they do not specifically involve the inflammation of the eyelids or conjunctiva. Impetigo is a contagious bacterial skin infection that mainly affects the face and other bodily areas but is not directly associated with the eyelid membrane. Seborrhea refers to excess oil production in the skin, often leading to dandruff or seborrheic dermatitis, but does not specifically involve inflammation of the eyelid's membrane either. Understanding these distinctions helps clarify why Pink Eye is the accurate choice in this context.
