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 ".
The vitreous humor is a transparent, colorless, gelatinous mass that fills the space in the eye between the lens and the retina.It is surrounded by a layer of collagen called the vitreous membrane (or hyaloid membrane or vitreous cortex) separating it from the rest of the eye.

A posterior vitreous detachment (PVD) is a condition of the eye in which the vitreous membrane separates from the retina. [1] It refers to the separation of the posterior hyaloid membrane from the retina anywhere posterior to the vitreous base (a 3–4 mm wide attachment to the ora serrata ).
Bruch's membrane or lamina vitrea [1] is the innermost layer of the choroid of the eye. It is also called the vitreous lamina or Membrane vitriae , because of its glassy microscopic appearance. It is 2–4 μm thick.
The vitreous base is an area in the fundus of the eye in which the vitreous membrane, neural retina, and pigment epithelium all are firmly adherent, one to the other. The vitreous membrane is more firmly attached to the retina anteriorly at the vitreous base. The vitreous membrane does not normally detach from the vitreous base, although it can ...
The hyaloid artery is a branch of the ophthalmic artery, which is itself a branch of the internal carotid artery.It is contained within the optic stalk of the eye and extends from the optic disc through the vitreous humor to the lens.
Weiss ring: a large, ring shaped floater that is sometimes seen if the vitreous body releases from the back of the eye. As part of the normal human aging process the liquefied vitreous body loses support and contracts. This leads to posterior vitreous detachment in which the vitreous membrane is released from the sensory retina. [9]
