Question: 1 / 400

Which part of the retina is most responsible for high-acuity vision?

The optic disc

The fovea

The fovea is the central region of the retina and is specially adapted for high-acuity vision. It contains a high density of cone photoreceptors, which are responsible for detecting color and fine details and function best in bright light conditions. This concentration of cones in the fovea enables sharp, detailed vision essential for tasks such as reading and recognizing faces.

In contrast, the optic disc is the point where the optic nerve exits the eye and lacks photoreceptors, which means it does not contribute to visual acuity. The periphery of the retina has a lower concentration of cones and is more sensitive to motion and dim light but does not provide the detail necessary for high-acuity tasks. The ora serrata marks the transition from the retina to the ciliary body and is not involved in visual processing. Hence, the fovea is the critical area for achieving high-definition vision due to its unique structure and composition.
