"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
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.
It is used as an aid in ophthalmic surgery acting as aqueous and vitreous humor, e.g. in cataract extraction (intra- and extracapsular), intraocular lens implantation, corneal transplant, glaucoma filtration, and retina attachment surgery and in the treatment of dry eyes. [11]
Vitreous floaters – deposits of various size, shape, consistency, refractive index, and motility within the eye's normally transparent vitreous humor which can obstruct vision. Here pars plana vitrectomy has been shown to relieve symptoms. [9] Because of possible side effects it is used only in severe cases.
[8] [23] [24] In this technique, the vitreous gel is removed from the eye to relieve the pulling force on the retina. [8] [10] Any fluid behind the retina is drained, and tears are sealed with freezing or lasers. [8] [10] The removed vitreous is then replaced with either a gas bubble or silicone oil, which stabilizes the retina.
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 ...
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.
Vitreomacular traction syndrome (VTS) is a medical condition in the eye that is the result of tractional forces (pulling) being placed on the retina. [ 1 ] [ 2 ] VTS is common in people who have an incomplete posterior vitreous detachment, a type of retinal detachment at the periphery of the retina. [ 1 ]
