Which segment of the eye is responsible for preventing the eyeball from collapsing?

• A. Anterior segment
• B. Posterior segment
• C. Corneal segment
• D. Retinal segment

Answer: (B)

The segment of the eye responsible for preventing the eyeball from collapsing is the posterior segment. This area is filled with vitreous humor, a gel-like substance that maintains the shape of the eyeball and provides structural support. The vitreous humor is critical for the eye's integrity, helping to counteract external forces and keeping the retina in place against the choroid, which is essential for visual function. While the anterior segment contains aqueous humor, which also contributes to intraocular pressure, it is the posterior segment's contribution of vitreous humor that plays the primary role in maintaining the overall shape and stability of the eyeball. The other segments, such as the corneal and retinal segments, do not specifically serve the purpose of maintaining the shape of the globe in the same way that the vitreous humor does.
