Vitreous membrane
Membrana vitrea
Definition
The vitreous membrane (a.k.a. the hyaloid membrane or vitreous cortex), is a thin transparent layer that forms the outer boundary of the vitreous body. It encloses the vitreous humor and separates it from adjacent ocular structures.
Anteriorly, the vitreous membrane is related to the posterior capsule of the lens and is attached to it peripherally by Wiegers ligament (hyaloideocapsular ligament). Posteriorly, it lies in close contact with the internal surface of the retina, particularly at sites of firm vitreoretinal attachment such as the optic disc and ora serrata.
