The pigmented layer of the eye?

• A. Choroid
• B. Uvea
• C. Cornea
• D. Pupil

Answer: (B)

The pigmented layer of the eye is the uvea, the pigmented vascular middle layer that lies between the sclera and retina. It includes the iris, ciliary body, and choroid, and it contains melanin to absorb excess light and reduce scattered glare. This layer also provides blood supply to the eye. While the choroid is a part of the uvea and is indeed pigmented, naming the entire pigmented middle layer as the uvea reflects all the pigmented components involved. The cornea is the transparent front surface, and the pupil is the opening within the iris; neither of these is the pigmented layer.
