Which statement best describes cone distribution in the retina?

Which statement best describes cone distribution in the retina?

• A. Densely packed in the fovea with fewer toward the periphery
• B. Equally distributed across retina
• C. Absent in the fovea
• D. Most located at the optic disc

Answer: (A)

Cones are densest in the fovea, the central part of the retina, which enables sharp, color vision. As you move away from the fovea toward the peripheral retina, cone density decreases, so there are fewer cones toward the periphery. This arrangement supports high-resolution central vision while peripheral vision relies more on rods for sensitivity in dim light and motion detection. The optic disc lacks photoreceptors, creating a blind spot, so cones are not most concentrated there. That’s why the statement describing cone distribution as densely packed in the fovea with fewer toward the periphery is the best fit.
