What is micropapilla?

What is micropapilla?

• A. Optic disc smaller in diameter than normal WITHOUT vision loss
• B. Very small retina
• C. Increased intraocular pressure
• D. Optic nerve head swelling

Answer: (A)

Micropapilla means a smaller-than-normal optic disc diameter. It’s typically a congenital variation where the optic nerve head is small, and vision remains normal because there isn’t swelling or damage to the nerve. This distinguishes it from conditions that either involve swelling of the optic nerve head or cause vision loss. So the defining feature is a small optic disc without any loss of vision. The other descriptions don’t fit: a very small retina isn’t the term used to describe the optic nerve head; increased intraocular pressure relates to glaucoma risk but isn’t what micropapilla is; optic nerve head swelling describes papilledema or other inflammatory processes, not a small, non-swollen disc.
