Vitreous membrane
Membrane within the eyeball surrounding the vitreous humor
From Wikipedia, the free encyclopedia
In human anatomy, the vitreous membrane (also called the vitreous cortex or hyaloid 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. It is a false anatomical membrane.[1]
- The anterior hyaloid membrane separates the front of the vitreous from the lens.[2]

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 Weigert's ligament, also known as Egger's line.
