Which set of numbers correctly lists the monocular visual field extents in the order superior, inferior, temporal, nasal?

• A. 60, 80, 105, 60
• B. 60, 60, 105, 75
• C. 60, 75, 105, 60
• D. 60, 75, 100, 60

Answer: (C)

Monocular visual field extents are the angular limits of vision from fixation in the four directions: superior, inferior, temporal, and nasal. The nasal limit is about 60 degrees because the nose blocks part of the field. The temporal limit extends the farthest, around 105 degrees, since there’s less obstruction toward the temple. The vertical limits are roughly 60 degrees upward (superior) and about 75 degrees downward (inferior), with the lower field often a bit larger due to orbital anatomy.

So the sequence is 60 (superior), 75 (inferior), 105 (temporal), 60 (nasal). That matches the given correct option.

These values are typical ranges used in clinical teaching; individual variation and testing methods can shift them slightly, but the general pattern and relative extents hold.
