Which statement best describes the vitreous body?

• A. A semisolid gel inside the eye that is clear and helps keep the lens and retina in place
• B. A watery fluid in the anterior chamber
• C. The outer fibrous protective layer of the eyeball
• D. A muscle that controls pupil size

Answer: (A)

The vitreous body is a clear, semisolid gel that fills the large space behind the lens in the eye. It acts as a structural support, helping to keep the lens and the retina in their proper positions and maintaining the eye’s shape so light can pass through smoothly to the retina. Because it’s transparent, it doesn’t interfere with vision, yet it provides a stable medium that helps hold the retina against the back of the eye. By contrast, the watery fluid in the front part of the eye is the aqueous humor, not the vitreous. The outer protective layer is the sclera, and the muscle that adjusts pupil size is the iris.
