Question 90

Question:

An 8-year-old male presents at a clinic in a rural Nepal with conjunctival scarring and ocular pruritus. His physicians are concerned with preventing progression to blindness.
Which of the following is the most likely underlying etiology?

Correct Answer: B.  Chlamydia trachomatis infection

Infection with Chlamydia trachomatis is the leading cause of preventable blindness in the world.
It is unlikely that a congenital malformation would result in conjunctival scarring and ocular pruritus.
Cataracts, macular degeneration or trauma are not suggested by the patient’s medical history, and should not be suspected without more information.
