Explanation:

Question 82

To determine the meaning of "Blephar/itis", we analyze the word parts. "Blephar-" refers to the eyelid, and "-itis" means inflammation. So we check each option:

• "inflammation of the tear duct" is incorrect (tear duct - related terms would have different roots).
• "softening of the sclera" is incorrect (softening is -malacia, sclera - scler-).
• "inflammation of the eyelid" matches the word parts (blephar- = eyelid, -itis = inflammation).
• "condition of white pupil" is incorrect (white pupil - related terms have different roots).

We analyze each option:

• "Pterygium" is a growth on the conjunctiva, not from staphylococcus infection of eyelid glands.
• "Conjunctivitis" is inflammation of the conjunctiva, not specifically from eyelid/sebaceous gland staph infection.
• "Blepharitis" is inflammation of the eyelid, but a staph infection of the eyelid's sebaceous gland specifically causes a stye, not just blepharitis in general.
• "Stye" (hordeolum) is caused by staphylococcus infection of the eyelid's sebaceous gland (like meibomian glands) or hair follicles.

Answer:

C. inflammation of the eyelid
