Eversion of the edge of an eyelid is called?

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

Answer: (A)

Ectropion is the turning outward of the eyelid edge. When the lid margin everts away from the eyeball, the inner conjunctival surface is exposed, leading to tearing, irritation, and possible exposure problems. This is different from entropion, where the lid margin turns inward toward the eyeball and lashes rub against the cornea. Conjunctivitis is an inflammation of the conjunctiva, not a mechanical change in lid position, and uveitis is inflammation inside the eye’s uveal tract. So the outward turning of the eyelid edge is ectropion.
