What is a vitreous detachment? A vitreous detachment is a condition in which a part of the eye called the vitreous shrinks and separates from the retina. The vitreous is a gel-like substance that fills the inside of the eye ball. The retina is a light-sensitive area at the back of the eye. A vitreous detachment is also known as a posterior vitreous detachment.
