Which of the following ocular tissues and infections is mismatched? Select one: a. Trachoma; infection of epithelial cells b. Keratitis; infection of deep eye tissue c. Conjunctivitis; milky discharge and infection of eyelid lining d. River blindness; microfilariae visible in the vitreous chamber

d. River blindness; microfilariae visible in the vitreous chamber

Explanation:

Trachoma is caused by Chlamydia trachomatis causing follicular conjuctivitis and also the infection of the epithelial cells hence this match is right.

Keratitis is associated with infection of deep eye tissue hence this match is right too.

In conjuctivitis there is a milky discharge from the eyes hence this match is right too.

While in the case of river blindness (onchocercosis) ,chronic microfilaria is in the cutis not vitreous chamber which is then observed in microscope.

Hence d. River blindness; microfilariae visible in the vitreous chamber is the right answer.
