Vitrectomy is a surgery to remove some or all of the vitreous humor from the eye.. Anterior vitrectomy entails removing small portions of the vitreous humor from the front structures of the eye—often because these are tangled in an intraocular lens or other structures.
"Surgical removal of the vitreous gel by a vitreoretinal surgeon can sometimes be performed to achieve symptomatic relief," says Dr. Sastry. 4. Consider other options for the most severe cases
The vitreous fluid is not present at birth (the eye being filled with only the gel-like vitreous body), but found after age 4-5, and increases in size thereafter. [1] Produced by cells in the non-pigmented portion of the ciliary body, the vitreous humour is derived from embryonic mesenchyme cells, which degenerate after birth. [1]
Vitreomacular adhesion (VMA) is a human medical condition where the vitreous gel (or simply vitreous, AKA vitreous humour) of the human eye adheres to the retina in an abnormally strong manner. As the eye ages, it is common for the vitreous to separate from the retina.
The vitreous humour, or vitreous body, is a jelly-like, transparent substance that fills the majority of the eye. It lies within the vitreous chamber behind the lens, and is one of the four optical components of the eye. [8] Thus, floaters follow the rapid motions of the eye, while drifting slowly within the pocket of liquid. [9]
Rhegmatogenous retinal detachment is most commonly caused by posterior vitreous detachment, a condition where the gel inside the eye breaks down and pulls on the retina. [4] [7] Risk factors include older age, nearsightedness , eye injury, cataract surgery, and inflammation. [7] [8]
The vitreous (Latin for "glassy") humor is a gel which fills the eye behind the lens. Between it and the retina is the vitreous membrane. With age the vitreous humor changes, shrinking and developing pockets of liquefaction, similar to the way a gelatin dessert shrinks and detaches from the edge of a pan. At some stage the vitreous membrane may ...
They are shadow images of objects floating in liquid between the retina and the gel inside the eye (vitreous humor). They are visible because they move; if they were pinned to retina by the vitreous or fixed within the vitreous they would be as invisible as ordinary viewing of any stationary object, such as the retinal blood vessels (see ...
