Which term means inward turning of the eyelid margin?

• A. Diplopia
• B. Presbyopia
• C. Photophobia
• D. Entropion

Answer: (D)

Inward turning of the eyelid margin is entropion. When the lid turns inward, the eyelashes and lid margin rub against the eyeball, which can irritate the surface (conjunctiva and cornea) and cause tearing, redness, and a sensation of a foreign body. This condition is commonly due to aging-related changes, scarring, or trauma, and it’s important to address to protect the eye’s surface. Diplopia refers to seeing two images (double vision), presbyopia is age-related difficulty reading up close, and photophobia is sensitivity to light.
