Vitreous membrane

from Wikipedia, the free encyclopedia

The vitreous membrane (also hyaloid membrane ) is a boundary layer consisting of collagen fibers , which separates the vitreous body of the eye from the retina , the lens and the ciliary body and connects them firmly.

anatomy

From an anatomical point of view, the membrane can be divided into two parts.

The posterior membrane separates the vitreous tissue from the retina in a dorsal direction. The anterior membrane forms the ventral boundary layer between the vitreous humor and the lens. The contact area between the vitreous humor and the lens is called the patellar fossa and corresponds to the impression of the posterior lens surface.

Bernal et al. describe the membrane as follows: "A delicate structure in the form of a thin layer that runs from the pars plana to the posterior lens, where it is attached to the posterior zonular fibers by the Weigert ligament (also known as Eggersche line) ".

histology

The membrane consists of collagen fibers , among other things .
