is the transparent, colorless mass of gel that lies behind lens and in front of retina. The spherical shape of the eyeball is maintained by this jelly-like substance.
Vitreous humour (British spelling) or Vitreous humor (U.S. spelling) is the clear aqueous solution that fills the space between the lens and the retina of the vertebrate eyeball. The solution is 99% water, but has a gelatinous viscosity two to four times that of water. The remaining solutes include salts, sugars, phagocytes, and a network of collagen fibers.
