Which term refers to the outward turning of the eyelid edge?

• A. Ectropion
• B. Entropion
• C. Conjunctivitis
• D. Uveitis

Answer: (A)

Outward turning of the eyelid edge is called ectropion. It means the lid margin turns away from the eyeball, exposing the inner surface of the eyelid and often the white of the eye. This can cause tearing, dryness, irritation, and sometimes corneal irritation because the eye is not being properly shielded by the lid. The other terms describe different conditions: entropion is the inward turning of the lid margin, causing the lashes to rub against the eye; conjunctivitis is inflammation of the conjunctiva with redness and discharge; uveitis is inflammation of the uveal tract inside the eye.
