Which eye compartment is a semisolid gel surrounded by retina that keeps the lens and retina in place?

• A. Vitreous body
• B. Anterior chamber
• C. Posterior chamber
• D. Retina

Answer: (A)

Think about the eye’s compartments and what fills them. The vitreous body is a semisolid gel that occupies the space between the lens and the retina, forming the vitreous chamber. This gel-like substance helps hold the lens in place and keeps the retina properly positioned against the back of the eye, contributing to the eye’s shape and optical stability. The anterior and posterior chambers, by contrast, are fluid-filled spaces containing aqueous humor and lie in front of the iris (between cornea and iris) and between the iris and lens, respectively. The retina itself is the light-sensitive tissue lining the back of the eye, not a gel-filled space. So the semisolid gel described is the vitreous body.
