"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
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.
Intravitreal injection was first mentioned in a study in 1911, in which the injection of air was used to repair a detached retina. [6] [7] [8] There were also investigations evaluating intravitreal antibiotics injection using sulfanilamide and penicillin to treat endophthalmitis in the 1940s, yet due to the inconsistency of results and safety concerns, this form of drug delivery was only for ...
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 (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 gel undergoes liquefaction (posterior vitreous detachment or PVD) and its opacities — visible as floaters — gradually increase in number. Eye care professionals , including ophthalmologists and optometrists , are involved in the treatment and management of ocular and vision disorders.
