Which cells are concentrated in the macula of the eye?

The macula of the eye, specifically the fovea centralis located within it, contains a high concentration of cone photoreceptor cells. These cones are responsible for daylight vision and are crucial for color perception and visual acuity. The macula is designed for high-resolution vision, enabling detailed tasks such as reading and recognizing faces, which is facilitated by the abundance of cone cells in this area.

Rods, while important for low-light vision, are primarily located in the peripheral regions of the retina and are not concentrated in the macula. Ciliary muscles are involved in controlling the shape of the lens for focusing but do not reside in the macula itself. Choroid cells, associated with the layer of blood vessels supplying the retina, do not play a direct role in visual phototransduction within the macula.

The high density of cones in the macula is what allows it to achieve its function as the region of the eye with the highest visual acuity.
