What is the typical appearance of a stye?

• A. A small yellow pustule at the base of an eyelash, surrounded by redness and swelling.
• B. Painless white dot on the cornea.
• C. Diffuse scleral injection.
• D. Blurry vision with peripheral field loss.

Answer: (D)

A stye is a localized eyelid margin infection that presents as a tender, red lump at the lash line, often with a small yellow pustule at the base of an eyelash and surrounding lid swelling. This yellow pustule at the lash base is the classic clue that the problem is an infection of the eyelid structures (like a hair follicle or meibomian gland). It does not involve the cornea, and vision is usually not affected.

A painless white dot on the cornea would suggest a corneal lesion or scar rather than a lid-margin infection. Diffuse scleral injection points to inflammation of the sclera or conjunctiva, not a localized eyelid infection. Blurry vision with peripheral field loss indicates a posterior segment issue such as retinal or optic nerve pathology, not a stye.
