This month's feature
is a normally clear, gel-like substance that fills the center of the eye.
It makes up approximately 2/3 of the eye's volume, giving it form and shape
before birth. Certain problems affecting the back of the eye may require
a vitrectomy, or surgical removal of the vitreous. After a
vitrectomy, the vitreous is replaced as the eye secretes
and nutritive fluids.
