Question

which of the following pathological conditions is a purulent infection of a sebaceous gland on the eyelid?
a oculomycosis
b hordeolum
c esotropia
d pterygium

Explanation:

• Oculomycosis: Refers to a fungal infection of the eye, not specifically a purulent infection of a sebaceous gland on the eyelid.
• Hordeolum: Commonly known as a stye, it is a purulent (pus - filled) infection of a sebaceous gland (Zeis gland) or a modified sweat gland (Moll gland) on the eyelid.
• Esotropia: Is a type of strabismus (misalignment of the eyes), where one eye turns inward. It has nothing to do with an infection of a sebaceous gland.
• Pterygium: Is a growth of conjunctival tissue over the cornea, usually due to chronic irritation (e.g., from UV light, dust), not an infection of a sebaceous gland.

Answer:

B. hordeolum
