Which fluid fills the large cavity between the lens and the retina?

• A. Aqueous humor
• B. Vitreous humor
• C. Tears
• D. Lymph

Answer: (B)

The large cavity between the lens and the retina is filled with vitreous humor. This gel-like fluid forms the vitreous body that fills the posterior segment of the eye, helping to maintain the eye’s shape and keep the retina pressed against the choroid for clear vision. It’s different from aqueous humor, which fills the front chambers (between cornea and lens) and circulates to nourish those structures. Tears coat the surface of the eye, and lymph is not a normal intraocular fluid. So the fluid in that space is vitreous humor.
