Which part of the retina has an area of high cone density?
A) choroid
B) optic disc
C) macula lutea
D) none of the above
Macula Lutea
A small, yellowish central area of the retina that is rich in cones and mediates clear, detailed vision.
Cone Density
The distribution of cone cells in the retina, which are sensitive to color and are used for high visual acuity.
Retina
A light-sensitive layer at the back of the eye, containing cells that convert light into neural signals sent to the brain.

Final Answer :
C
Explanation :
The macula lutea is a small area in the central part of the retina that contains a high concentration of cone photoreceptor cells, which are responsible for color vision and visual acuity. This is why the macula lutea is also known as the "fovea centralis", which is the area of the retina that produces the sharpest and most detailed vision. The choroid is a layer of tissue that provides blood supply to the retina, and the optic disc is the point where the optic nerve enters and leaves the eye. Neither of these areas have a high cone density.
