Vitreous membrane
Encyclopedia
The vitreous membrane 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
The anterior hyaloid membrane separates the front of the vitreous from the lens
.
Bernal et al. describe it "as a delicate structure in the form of a thin layer that runs from the pars plana
to the posterior lens, where it shares its attachment with the posterior zonule via Wieger’s ligament, also known as Egger’s line".
Collagen
Collagen is a group of naturally occurring proteins found in animals, especially in the flesh and connective tissues of mammals. It is the main component of connective tissue, and is the most abundant protein in mammals, making up about 25% to 35% of the whole-body protein content...

Vitreous humour
The vitreous humour or vitreous humor is the clear gel that fills the space between the lens and the retina of the eyeball of humans and other vertebrates...

Human eye
The human eye is an organ which reacts to light for several purposes. As a conscious sense organ, the eye allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth...

Retina
The vertebrate retina is a light-sensitive tissue lining the inner surface of the eye. The optics of the eye create an image of the visual world on the retina, which serves much the same function as the film in a camera. Light striking the retina initiates a cascade of chemical and electrical...
The anterior hyaloid membrane separates the front of the vitreous from the lens
Lens (anatomy)
The crystalline lens is a transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina. The lens, by changing shape, functions to change the focal distance of the eye so that it can focus on objects at various distances, thus allowing a...

Pars plana
The pars plana is part of the uvea, choroidea, one of the three layers that comprise the eye. As a part of the ciliary body, it is about 4 mm long and located near the point where the iris and sclera touch....
