The vitreous makes up approximately what percent of the globe?

• A. 60%
• B. 70%
• C. 80%
• D. 90%

Answer: (C)

The vitreous body fills most of the eye by volume. In a normal eye, it occupies about four-fifths of the globe, roughly 80% of the total volume, spanning the posterior segment from behind the lens to the retina. The remaining space (about 20%) is taken by the anterior segment structures, including the cornea, aqueous humor, lens, and other tissues. So, 80% is the best fit. Numbers like 60% or 70% would understate how much the vitreous fills, while 90% would overstate it since there are still sizable anterior structures occupying space.
