What is the term for vision loss in peripheral fields?

• A. Central vision loss
• B. Night blindness
• C. Tunnel vision
• D. Color blindness

Answer: (C)

Tunnel vision refers to the loss of peripheral vision while retaining central vision. This condition is often associated with various eye diseases and conditions, including glaucoma and retinitis pigmentosa. In tunnel vision, the individual's field of view narrows significantly, creating a "tunnel-like" effect, where they can only see straight ahead without awareness of surrounding objects. Central vision loss, on the other hand, involves a loss of vision in the central visual field and does not affect peripheral vision. Night blindness pertains specifically to difficulty seeing in low light or darkness and does not describe any peripheral loss. Color blindness describes an inability to perceive differences in color and is not related to field loss. Thus, tunnel vision is the appropriate term to describe the condition of vision loss in peripheral fields.
