The vitreous body at birth is homogenous with a finely striated pattern. With early aging the vitreous develops narrow transvitreal "channels". The cortex is denser than the centre with development. From adolescence, vitreous tracts form from anterior to posterior. These vitreous tracts are fine sheet-like condensations of vitreous. Named tracts

Moore's lightning streaks are lightning type streaks (seen to the temporal side) due to sudden head or eye movement in the dark. They are generally caused by shock waves in the vitreous humor hitting the retina or traction on the retina from fibers in the vitreous humor.
The membrane does not normally detach from the vitreous base, although it can be detached with extreme trauma. However, the vitreous base may have an irregular posterior edge. When the edge is irregular, the forces of the vitreous membrane peeling off the retina can become concentrated at small posterior extensions of the vitreous base.
The vitreous membrane (or hyaloid membrane or vitreous cortex) is a layer of collagen separating the vitreous humour from the rest of the eye. At least two parts have been identified anatomically. The posterior hyaloid membrane separates the rear of the vitreous from the retina. It is a false anatomical membrane. [1]

Doctor Sundeep Khosla is a professor of medicine and physiology at the Mayo Clinic. "Everybody shrinks as we age: women and men," Khosla said. One of the reasons for shrinking with age is ...
Long term vitreous traction (stretching) of the retina is thought to be what is associated with the increased risk of tears to the retina or retinal detachment. [1] Under a microscope looking at the histology of a cystic retinal tuft, an increase in glial cells , breaking down of the outer retina, and a loss in photoreceptor cells is often ...
