Entropion is a sign commonly associated with Trachoma.

• A. Gonococcal conjunctivitis
• B. Phlyctenular keratoconjunctivitis
• C. Bacterial conjunctivitis
• D. Trachoma

Answer: (D)

Entropion in this context comes from scarring of the inner eyelid surface caused by chronic trachoma. The persistent inflammation leads to cicatrization of the tarsal conjunctiva, which pulls the eyelid margin inward. When the lid turns in, the lashes rub against the cornea (trichiasis), causing irritation, corneal a pannus formation, and potential vision loss. This inward lid turning due to scarring is a classic sign of trachoma's cicatricial phase.

The other conditions listed don’t typically produce this kind of tarsal scarring and inward eyelid position. They can cause discharge or superficial inflammation, but they don’t usually lead to the chronic eyelid distortion seen with trachoma.
