Inward turning of the rim of the eyelid is called which term?

• A. Ectopion
• B. Periorbital Edema
• C. Entropion
• D. Diplopia

Answer: (C)

Turning inward of the eyelid margin is entropion. In this condition, the edge of the eyelid loops toward the eye, causing the lashes to rub against the cornea and conjunctiva. This irritation can lead to tearing, redness, and even corneal damage if not treated. It’s different from ectropion, which is the outward turning of the eyelid edge away from the eye, leaving the inner surface exposed. Periorbital edema is swelling around the eye, not a change in the eyelid’s position, and diplopia refers to double vision, which isn’t about eyelid orientation. Entropion best fits the description of inward eyelid turning.
