What is the choroid?

What is the choroid?

• A. A protective outer coat that maintains eye shape.
• B. The light-sensitive inner layer of the eye.
• C. A vascular layer rich in blood vessels that supplies nutrients and gives the eye its reddish hue.
• D. The transparent layer that covers the iris.

Answer: (C)

Choroid is a vascular layer situated between the sclera and the retina. It contains a dense network of blood vessels that deliver nutrients and oxygen to the outer retina, supporting the photoreceptors. Its pigmentation helps absorb stray light, reducing glare, and the extensive blood supply gives the eye its reddish hue. This layer is part of the uveal tract, distinct from the sclera (the protective outer coat that maintains eye shape), the retina (the light-sensitive inner layer), and the cornea (the transparent front layer).
